So I own 5 different sets of adjustable rockers for SBM LA engines. One set are original Mopr W2 iron rockers.One set are aftermarket iron adj. rockers with roller tips. The other three sets are regular LA adjustable rockers, but all three are different from one another. One set is standard 273...

So, I kinda ended up with a ‘67 Valiant two door in a trade, which I probably don’t need, but I might keep it anyways. So if I keep it, it will be a super low buck driver. Something that I can drive anytime and anywhere on pump gas, highway cruising would be a must, and I would have to put it...

Ok, so try and hang with me for a minute. So I have a '64 Dart. Its latest setup was a 360/4spd/8.25" 3.55 SureGrip that ran 8.60s in the 1/8th mile and was very drive-able. This wasn't enough for me, so I've since pulled the entire drivetrain out front to back with plans of a 340/416 stroker...

So I've got a pair of ported W2 heads and an Eddy W2 Victor intake. Intake manifold is ported to match. Heads were professionally ported at some point. The heads have valves, springs, retainers and keepers. I'm looking to sell, as I need to get some ported LA heads for my 360 I'm building. So...

So the engine in question is in my truck. Rebuilt '74 shortblock, "302"heads cut 0.030", stock rockers, hydraulic lifters, stock pushrods, MP springs, CompCams XE262 cam. Once assembled and hot, the pushrods seem to be a fuzz to tight in the rocker. I can BARELY rotate them in place. Could...

So I'm ready to make my dart a little wilder than it is! Currently it's just a 360, with H116CP pistons, (scr is at 9.4:1 with standard felpro head gaskets), CompCams 268AH-10, untouched small valve 587 heads, 340HP manifolds, Eddy LD340 intake and a 750cfm Street Demon. The car is backed by a...

Alright so I'm about to redo the engine/trans/rear-end/brakes on my '77 D100. The truck is a single cab long bed and weighs 3800lbs without me in it. It's a 2wd with a 318/727/8.25 in it. It haos served as an on and off daily driver and my only truck for more than 5yrs now. The old original...

So I responded to an ad on CL recently about a 318 for sale for $1000. The ad said it had about 7000miles on a rebuild, and that he pulled it to put a hot 340 in his restored duster. He didn't build the engine or the car, he had purchased from a dealer out west that specialized in old Mopars...

Anybody know what the specs are on this cam?! It has a "891492" stamped on it.

So long story short, I need opinions on a camshaft. Here's my dilemma. I have a '64 Dart that I play with and a '77 D100 I use as a parts hauler. The Dart has a 360 I rebuilt and put in last year. Specs are as follows: 1970 block 0.06" over (371cuin) Stock crank and rods SpeedPro H116CP...

About to slide the cam in my LA 360 and am curious as to if I should advance or retard the cam, or just run it straight up. The build is as follows: '70 360 .060" overbore SpeedPro H116CP pistons Measured SCR of 9.3:1 Stock crank and rods Cleaned up 587 heads with 1.88/1.60 valves LD340 intake...

So I'm about to assemble my mild 360, and am nearing the point where I need to buy pushrods. The dilemma is I'm running a CompCams 268AH-10 which is hydraulic, Comp cams Hyd lifters and I intended on using a set of OEM adjustable 273 rockers. So far, I've come up with these from CompCams...

So I just scored a '68 cast 340 out of a '69 dart for $700. It's disassembled, but mostly complete and completely unmolested! The only things missing was the intake, cam, and valve covers. All of which I would be replacing any ways. There is no ring ridge in the cylinders and it's stock bore...

I know this is a potential Pandora's Box, but what's the deal with so many people saying that you cant run 10:1 compression, stock iron heads, and a "mild" cam on pump gas?! My confusion is, stock early 273HP and 340HP came from the factory rated at 10.5:1cr, with iron heads and what was a...

I'm trying to get some real world feedback from people actually running the Comp XE268 in their car. How's the power and torque? How's the driveability? Economy? Etc.?

Ok, relevent specs are as follows: 1964 Dart 170 2dr sedan 2800-3000lbs Manual brakes 4spd overdrive 8.25" rear with 3.55fd SG 26" tall rear tires 360 .060 over (371ci) H116CP SpeedPro pistons Hypereutectic Measured cr of 9.8:1 Other wise stock bottom rotating assembly Stock 587 heads with...

So I'm about to start getting together the last of my bits for my 360 swap into my '64 Dart. I've got a few blanks I need filled in. The plan for this car is a fun daily driver/cruiser. Not a race car or a miser but somewhere in between. The engine will be backed by an A833 OD and an 8.25" rear...

How much lighter would an LA small block be if you swapped out for all the lighter parts you can? Aluminum heads, intake manifold, water pump, headers, etc.?

So I've got a warmed over 360 that I'm gonna put in my '77 D100, and I wanna run my TQ that I picked up awhile back. The 360 is a .060" over '70 block with hyperutectic flat tops(9.8:1cr measured), fresh 587 J heads, and a Comp 276H cam with matching springs. It's essentially a slightly...

So Im building me a bit of a rat gasser out of my '64 dart 2dr post. Im trying to keep it fairly period correct, the period being the early '70s. Well Ive have a 1970 casting date 360 that was rebuilt not to many miles ago. The rebuild consisted of a .040''-.060'' overbore, new pistons with a...

So, I picked up a 360 for my '76 Dart Sport('72 Demon clone) which is currently a slant/3 by the knee car. I wasnt really looking for a v8 and had intended on just building up a spare 225 I had an sticking a 4spd od behind it. Then a local oldskool Mopar guy(Wayne Bowden) mentioned he had a...
