318 combo's

-
ive got a 318 that needs to be pepped up does any one have suggestions for a cheap rebuild. ive also have a set of 596 heads off a 360 that have been angle milled .040, would i be able to use this heads
 
Hard to say without knowing your budget. Looks like you have the heads already covered,but I really know nothing about angle milling other than it's intention is to "raise " the port roof. I have no idea how well they work or seal up...maybe Moper or BJR can help???

I consider a tight budget to be under $1000 bucks. Thats a shade tree hone and regasket,or possibly a quicky bore/hone and cheap pistons etc. An Engine Teck kit is about the cheapest I've found,includes all gaskets, seals,double roller timing chain+gears, HV oil pump,mild performance cam/lifters,and 1.74 ch pistons/rings. Probably be about $400,then add in machining.And that will depend on who does it and how well you know them..
 
The 318 in the Demon was done on the cheap.

Rebuilt '68 318 with TRW kit
302 heads
Performer
625 AFB
Crane 276/286 duration .441 lift

The engine develops 9.3:1 compression ratio. Have not put on dyno or track, yet.

904 with TransGo RV shift kit

With this I have about $700 in the motor & transmission.

Currently has BBP 7¼ rear with 2.76 rear. Have 8.75 in process with 3.55 gears. At the rate I'm going, I'll have about $1400 in the drivetrain.
 
A 318 is nothing but a little 340 do the work with the right heads and you can stomp some chevy a** easy!
 
the block is off a 72 duster so the compression is like 8.5: 1, i would like to have it closer to 9.5: 1. should i get it decked or do they make pistons to fix this problem
 
I never really understand when someone here posts for help building a 318 and they are told to build a 360.I think if a guy is asking for advise about his 318 it's because it's he's got,can afford or he just wants to be different.

The 318's only real limitations stem from low compression,small cams and small ports/valve combo.
The bore of the teen is actually not much smaller than the LS1. Thats really no big deal. All the other stuff can be solved.
 
Hi cory,

always knew you wanted a convertible...lol, much more lighter than before...:toothy10::toothy10::toothy10:

That is how I feel. I almost went with a 360 build but everyone does that. That is like buying a chevy and putting a 350 in it. The 318 is legendary lol
 
how much trouble is it to make a 360 crank fit into a 318. would i have to have 4 bolt mains put in and would there be clearance issues
 
It's not hard. If using a 360 crank,simply have the main journals cut down to 318/340 diameter. Pistons are tricky,but off the shelf low compression hieght 318 truck pistons ( 1.658 ) can be made to work with a little clearancing of the skirt and you get a streetable compression ratio.

Scat makes a crank especially for this combo. Retail is about $300 from Summit.

BJR has a thread about this combo in the tech archive. I have to give him credit. His idea originally. It's an older build tecnique,racers did it back in the day when there wasnt any other stroker cranks.

You dont need 4 bolt mains in a sbm unless your going trans am racing...
 
Hi guys
Here is my combo
1978 DodgeRam block and tf727
915 heads, with 1.88,1.6 valves
edelbrock Performer cam 2177 270/270/ .420 - mild
Edelbrock Performer intake plus 600cfm Edelbrock Carb
everything is ported, gasketmatched bleprinted and ballanced
Running 9.35 cr
and 340 HP exhaust manifolds 2 1/2 dual with x
Result 348hp @5500
370 lbft @ 4500 - 300 available from 1800
My cam is limiting me but this engine was a bitzer stuff i had lying around
In my 68 Barracuda it is Greatfun to drive
 
In 1995 we built a 1st yr apprentice cheap as chips 318 for my VH Hardtop with 904 2.92 open gears ran 14.8 @ 93 with 2.09 60 ft with standard '74 318 heads, std valve and springs with nothing more than k-liners and valve grind. The std bore 318 was decked .040 and refreshed with a Heatseeker 276 deg .420 lift cam. 600 vac on a Holley street dominator intake(a very good 318 manifold), genie extractors with twin 2" system. No big deal but very cheap. This little motor gave me years of fun breaking a rocker arm and cracking a flex plate while handing out beatings on Adelaide Chrysler cruises.
Since then its had 273 heads with 265 valves, LD340 intake with divider removed with 600 AFB, pacemakers with 2 1/2" system when in the CM SE 727 2.92 for a few years.
Now it's back in the Hardtop with Eddy heads, Holley strip dominator intake with 600 AFB with 1/2" fuel lines, big port HP (pacemakers). Accel billet dissy and coil with 3000 stall full manual 904 and 3.23 lsd. Recently fitted 1.6 stainless rollers. Hope to run this on the dyno or ?track? before it gets pulled out for a 'hot' 318 4000 stall and 4.11s

I love the 318 and do a lot research on them and talk to people who run high tens and elevens with them to understand them and I dont care for 4" cranks.
 
My first "Teen" went 13.92 @ 98.** mph in the 1/4, 3.55 gears regular 14 inch rubber. It was: stock short block, Crane Blazer cam, 273 heads cut .030, 1.88IN, 1.6EX valves, E-Brock Performer intake, 3310 Holley, Thorley "D" Dart headers, car was 65 Barracuda, full interior.

My last "Teen", still a stock short block, radically angle milled 360 heads(45.5cc chamber), 2.02, 1.6 valves, Comp Cams XTQ281S-6 cam, E-Brock Torquer2 intake, 750DP Holley, Thorley "D" dart headers, 4.88 gears, M/T 275/60x15 drag radials, gutted interior, it went 12.54 @108 mph in the 1/4.
 
my 1972 Duster Twister went 13.9 @ 102mph with a stock low comp '78 block 273 heads 1.96, 1.6 valves, Perfomer intake 600 afb 2800 stall 3.7 gears

'72 Duster with '78 block CCH302, LD340 600 afb, Eddy heads 4000 stall 3.7 gears but no track since 2005 to run on only the street

68 318 stock internals, 670 Holley Street Avenger, Edelbrock Performer, Pertronix Ignitor, Cyclone full length headers 1/5/8 to 3" collector 3" X-pipe 3"entry 2.5" exhaust 50 series flowmasters, 904 Cope Racing full manual valve body with low band apply, heavy duty band strut, billet servo, 2.7 1st gear 1.54 2nd gear, stock converter (for now). 8.75 489 case 3.23 sure grip. RHS Indy 2.02 heads and enough compression and cam that 91 octane allows when money is available, maybe 4"crank for 390 stroker. For the time being, great throttle response, 1st breaks the tires loose easily and is a fun cruiser, exhaust has a nice growl to it.

Here's my combo:

318 .030 over
KB399 pistons
340 forged crank ground .010/.010
studded mains
Eagle SIR rods
Mopar windage tray
Melling HV oil pump
Milodon Street/Strip 8qt pan & pick-up
Comp solid cam 236*@50/.495 lift
iron 1.5 mopar rockers
587 casting heads rebuilt/ported by Aerohead, 2.02/1.60 valves
viscous fan
Victor 340 intake, port matched
1" open plastic spacer
650 Holley DP
36* total timing, no vacuum advance
approx 10.5:1 compression
Hedman 1 5/8" street headers

727 with a TransGo TF2 shift kit
PTC 9.5" converter, stalls @ 3600

3.91 gears with crappy, old 26" slicks

Car's a bit of a porker, weighing in at 3640 with me behind the wheel and a full tank of gas. The transmission's been on the fritz for a while too and has some serious binding problems in the forward gears (don't worry, it hasn't been raced like that). Managed to click off a best of 13.5 @ 100 MPH, but I think there's more in there yet. :grin:

Any update on this 318?

This drivetrain was pulled and the car was traded off. The engine sitting on a stand right now in the shop waiting for its new home, a late-80s Dakota.

It ran a 13.27@101 before the car was pulled apart. It'll be going in the Dakota with a little bit bigger cam and a much steeper gear.
