Ok, let's hear what we've all done. I'll list two, with intended usage, the whats and whys, and the costs.

Budget 408: Goals of low cost, low maintenance, 5500 redline, power in the 430hp @ 5000rpm, 500tq @ 3200 range

Machining is where I dont skimp at all. Straight, flat, square, and balanced goes a long way to keeping average parts alive and making good power. So, the base stroker shortblock: clean, sonic test, align hone, square deck, bore, plate hone to ultra smooth finish, clearance for stroker crank/rods, deburr valley and oil drains, enlarge main feeds to 5/16, radius oil passages at filter plate, recon rods, bush pin ends for floating pins if not original, narrow pin ends if not Magnum rods, clean, install cam bearings/block hardware, mockup, assemble complete, degree cam. $2150

Parts: ARP main bolts, rod bolts, head bolts. Eagle cast crank, KBhyper pistons, SP rings, Cleavite/Durabond bearings, Comp cam/lifters/pushrods. Summit timing set, intake manifold, distributor. Edelbrock carb. Melling oil system. MP HP oil pump kit, oil pump drive, fuel pump eccentric, windage tray, rockers and shafts. Airtex fuel pump, water pump. FelPro gasket set. Mr G Tstat, intake gasket, header gaskets, air cleaner assembly. Dorman block hardware. Taylor wires. Autolite plugs. Gates hose. Reuse stock pan, timing cover, valve covers, slinger, dipstick and tube, oil filter housing/adaptor. $2990

heads: reuse any 340/360/Magnum iron castings. Complete go thru with performance in mind. so, guides, exh seats, 2.02-2.08 intakes, 1.65 exh stainless valves, guides trimmed, spring seats cut, gasket match, bowl blend, setup with matched springs, keepers, locks, milled for correct finish. $1200

Total: $6340 complete, air cleaner to full oil pan

Street/strip 416: goals of pump fuel, average maintenance, 6500 redline, power in the 525-600hp, 500-550tq

Machining: same as above minus $150 for using new rods. Possibly add $550 for lifter bore bushings and roller cam lifter clearancing. It's not a secret that good machining is the same on any displacement engine. With roller cam $2550.

Parts:ARP main studs, head bolts. Eagle H beam rods. Diamond forged pistons. C&A rings. King/Cleavite/Durabond bearings. "?" cam/lifters. Smith Bros. pushrods. Summit timing set. Edelbrock intake. Holley carb. Melling oil pump. MP cast crank, HP oil pump kit, oil pump drive, valve covers, timing chain tensioner. Crane rockers and shafts. Milodon pan, pickup, windage tray. Airtex water pump. FelPro gasket set. Mr G Tstat, intake gasket, header gaskets, air cleaner assembly. Dorman block hardware. MSD distributor. Taylor wires. Autolite plugs. Gates hose. Reuse stock timing cover, slinger, dipstick and tube, oil filter housing/adaptor. $5550

Heads: Edelbrock 63cc RPM, heads corrected, cc'd, fitted with matching springs, retainers, locks, ports cleaned up to remove CNC marks, gasket matched, milled with proper finish for gasket type. $2250

Total $10350.00 That again, complete carb to full oil pan, with a solid roller. A flat tappet would be about $9000. Pricing is off the top of my head, and I'll always lean towards the higher figure. I'd rather be high and have you not surprised, then say "$6000" and have all kinds of flailing when it's only the bare longblock for that $$.

"Your results may vary..." flame away! :D
 
One day Im going to add a 4" crank to my 340. You can never have to much torque on the street !
 
wow building engines is expensive, this put into perspective of how much stuff costs...dang, sure im not going that radical but wow thats alot

This is a good time to add something. I know we have more stroker builds here!
 
Moper,
what block did you use for the 416?
I have been told many times that the old 340 blocks would self destruct above 500Hp. This is why I have always been looking for a R3 block for the build. My goal is 600Hp. Opinions/experience anyone?
Andrew
 
For a taget of 600 hp and longevity, I'd look for a R block myself.
 
I hope this keeps rolling. I'd like to build one myself.

The factory blocks have thier limits. But, with careful parts choosing, machining, and assembly, the blocks will live at 550 all day long, and around 600 for a while with nothing more than steel caps, main studs, and lighter rods and pistons. But, if someone is planning for a true 600hp, AND CAN AFFORD TO BUILD ONE THAT MAKES THAT POWER, then they should get a new stronger block. For most people, 600hp is a magazine level they want to reach. not a realistic goal for what they can spend.

EDIT: I should add that with the price of the caps, studs, and lifter bore bushings, plus the competition level machining required... you are within about $1000 of a much better block. When the buget is $10K, $1000 more for strength and reliability is nothing.

Was the base for your motor an 89-92 truck motor?

Are you using stock rockers, push rods, and roller lifters?

Brian
 
My engine is a very nearly bone-stock, 1998, 360 Magnum that has a mild Hughes cam (214/218 @ .050"), some minimal valve bowl porting and a 3-angle valve job. Stock everything else except for the TTI headers, Air-Gap-style Chinese intake manifold, and a windage tray and M-P distributor.

I added a Vortech supercharger, for 10 pounds of boost. A 750cfm., 4150 Holley dbl. pmpr. supplies 110 octane av gas with an MSD Boost Retard and a Snowperformance BoostCooler alcohol injector spraying pure methanol. starting at 3 pounds of boost.

I haven't run this combination for very long.... I have 3 dyno pulls (445 rw hp/477 rw torque) and 6 runs down a 1,000-ft. drag strip (9.79 @ 106) on it so far with no apparent damage from detonation.


I bought an Eagle, 4", cast crank and a set of I-Beam Eagle rods for it the other day, and, when I can find the money for a set of forged pistons, and some Cometic head gaskets, I'll have a new 402-cubic inch short block to play with. I have plans to add a second Vortech supercharger, blowing into the same carb at that time, for probably, 15 pounds of boost. That should wake it up a little further. The blower setup added 185 rwhp to the 260 rwhp it was making, normally-aspirated. It was pretty weak, because it only had cast iron manifolds and a low-rise intake, to go with that exceedingly mild cam.

My question is this:

What do you think the lifepan of that Chinese Eagle crank and I-beam rods might be, pushing 15 pounds of boost?

Since it made approximately 525 flywheel hp (85-pct. of 525 is 445) with one blower, and a 3.58" stroke, how much of an increase do you think I might see with the 4" crank and a second supercharger blowing 50% more boost (15 pounds vs. 10) into the same carb?

Will it live long enough for me to get it to the dyno???????? LOL!:angry7:

What do you think??????
 
These are the parts I've collected so far for a 408:78 E-58 ( big deal, right? ) 360 block .030 over, Eddie RPM's ( new in box off ebay from a guy for $1100), Eagle cast 4 ", Scat H-beams w/ 190k ARP's, Probe forged ( 10.3 w/Eddie's), Total Seal gapless rings, ARP Main stud kit, Pro-something Aluminum Roller Rockers, Comp Cams XE285XL cam/lifters, Weiand X-celerator intake, MP Electronic Distributor w/Silver Box, Kevco pan, Melling HV pump, Cloyes Tru-Roller chain, Holley 800 DP(barely used). I've got about $4000 so far and I haven't had any machine work/balancing done yet and need to pick up gaskets and bolts and stuff. PS... the Fortune Cookie that came with my Chinese Crank said " Confucious Say He Who Does Crappy Machine and Assembly Job and Does Not Balance Engine Must Not Blame Chinese Parts!"

That's honkin'... normally aspirated!

I'm impressed! :cheers:
 
The 340 block is really not as weak as some people think, it was the engine of choice until they started to become extinct in the mid/late 80's you just need to take the correct steps when choosing parts and not take short cuts on the machine work, which is basically the same rules with any build.

I don't have my specifics in front of me but here is a quick run down of my engine.
340 block
Hugues girdle with .005 thousands pre-load
ARP studs.
Eagle 4" crank
Eagle H beam rods
JE pistons w/8.5-1 (nice pistons but they can't read an order form and their customer service sucks)
Comp 578 lift solid roller cam
65 cc Edlebrock heads mildly ported with bigger springs.
Crane gold race roller rockers
BDS 671 over driven 3%
Final comp 12.4-1
Demon 750 blower carbs
MSD ignition
 
Here's my Junk,

360 block, pump gas, 10.8:1 compression, 410 ci
Eagle 4.00 steel crank, Scat I-beams, Diamond pistons, total seal rings (file fit),
ARP main/head studs, Edelbrock heads stage II ported by Ryan J @ shadydell,
Small solid roller 248/254 duration w/ .576/.582 lift, Airgap (soon to be replaced w/ Victor),
Proform 750 dp (soon to be replaced w/ 950 dp)

Probably around 520 hp, street driven with an 8 inch converter that is a little looser than it should be. All through 3 inch muffs.

Lost track of the cost…but it wasn’t cheap. Still tuning, times are in sig.
 
Here is the combo I had in my 'Cuda:
360/408
Eagle steel crank,I beam rods,Probe pistons, file fit rings, 10.5:1, zero decked, line bored, torque plate hones, Eddy Magnum heads w/clean-up and gasket match and upgraded springs, Eddy Magnum RPM intake, Holley HP Street 750, Hughes hydraulic roller cam 228 @0.050" (HER2228?), pulled 11" Hg at idle, ARP studs, Comp Promagnum 1.6 rockers, TTI headers, est 460bhp based on Hughes Engines testing, quite docile around town but pretty mean at WOT, never dyno'd or tracked:thumbdow: (sold) I could easily bump the hp up with more cam and some minor porting. Hughes said a bigger cam was pointless without porting.

I didn't add up the cost but remember thinking about $7500??? Cdn. The hydraulic roller cam was costly.
 
well i'm in the process of doing my 408. i'll list what i have so far to best of my memory. A lot of the things like cam and machine work was taken care of Greg (family friend) at SS/AFX

95 magnum 360
4" eagle steel crank
magnum rods
arp rod bolts
hyd. flat tappet cam
ross pistons
file fit rings
eddy alum mag heads
sfi damper


Not sure how much i truly have in the engine at the moment or will have when its done but i do know that i've spent so far $17,000 on my duster (not including inital cost) to get to the point i'm at now and still have a lot more to go.
