Any suggestions as to which power valve I should use for this n/a 252 with the Comp cams 206 roller cam? It seems to be running ok, the engine will eventually die as I lean out my idle screws, so I think I have most of the jets sized correctly.....but the plugs are black as hell, which makes me...

Does anybody have an 231/252 engine with the Comp Cams 206/206 roller? I have FINALLY got my 252 v6 up n running. OK background info: I had the machine shop re-work the heads with the Comp cams suggested springs. They bored/honed the block and balanced the rotating assembly. The pistons...

I got the 231 v6 motor mounts mixed up and want to know which one goes on the drivers side. the one with the thin or thicker rubber "nub" in the center? thanx all!!

Hello all, I have a 252 N/A engine getting rebuilt. I just got back my boxes of parts to re-assemble my engine. I noticed that three of the rods have the double bump/dimple opposite side of the piston direction notch. The machine-shop foreman just told me that the rod bearing surface notches...

How far undersize can a 4.1 or turbo crank be ground/polished? I've got a crank that is .020 under for both mains and rods. Can it be safely ground .030 or should I find a new crank? Its going into a relatively stock carburetor fed 4.1.

My first question is: I'm building a N/A 252- the original 252 crank is already .020 under and now has slight grooves in the mains. So I'm afraid to have it ground any more. I have a fresh .010 under 231 crank. I know the filleted crank of the 252 is stronger, but is it necessary in a stock...

FYI....As of yesterday-12-29-10, there is a '76 dark blue Buick electra 225 with a complete 455 and trans in the u-pull-it junk yard @ 141th & western ave (2247 w 141st ST. 1-866-878-5548). The yard prices last I checked are: $150 & $25 core for the engine/no accessories, $200 with...

This isnt mine, but I thought somebody might want a crank with the filleted bearings. its item# 400154690343. hope this helps somebody! peaceout.

1- Can stock rods be bushed to accept a .93 or .92 diameter piston pin? 2- Or conversely, can the piston pin end be bored to accept a .98 diameter pin? Or should I ask what diameter can a stock rod piston end be bored to? 3- Is this a process an average machine shop can do? thanx in...

I've been reading again.... my fault. Has anybody done this? The cost of custom 252 pistons has me thinking the Chevy pistons and different rods would be cheaper. Or is this whole thing not worth the effort and basically just a waste of time?:confused:

Its time to build my next engine, but I cannot decide what to do with my garage full-o-parts! I'm contemplating a 252 build instead of the usual 231. I have a complete set of '83 231 heads, and I'm trying to figure what to put them on! Will they physically fit the 252 block (I'm guessing so)...

I think I found a rear for my 75 4dr century. The fellow says his 76 malibu wagon has a coil spring rear. Will it fit? what I really mean is-will the angles be right for the trailing arms, and the same location of the spring coils? thanx all!!!:thumbsup:

I am looking for a new rear gear for my 75 century, but I've figured it will probably be easier to swap out the entire rear end rather than pay labor and risk having the gears swapped out improperly. So what other rear ends fit the 73-77 A body? Or am I limited to those years? thanx...

I am just about ready to replace my stock 2bbl setup for the Offy Dual-port intake and Holley 390 CFM carb, but I would like to know the suggested power valve for this thing? Any ideas? Its a stock-cam oddfire '75 231 pushing a 75 Century with a 200-4r & 3.42 rear gears. I know I should also...

In responding to another thread, I figure I should just post this stuff to everybody (just in case somebody gets any ideas to help cure that go-fast bug) Centrifugal superchargers. They are low-profile and can still deliver a decent bang for your buck. They can be adapted to any engine...

I just bought a 89 Park Ave. it runs fine, but when I mash the pedal from a stop, it stumbles... and once it even backfired and died. Slower acceleration is fine, only WOT is a problem. any suggestions whats wrong?:confused:

I just found this excellent web blog comparing the reluctor and pickup coils from an oddfire and an evenfire. It has good pics as well as explanations. If the 225/231/252 is your bag, check it out.....:thumbsup: http://users.arczip.com/themotorpool/mopool/html/id93.htm

OK, I'm rebuilding an '83 231 v6, and I now need to know which type of flywheel/flexplate to buy. do I need a internally balanced or externally balanced flexplate:confused:??? thanx in advance.

I figure I should re-post this as its own thread, just trying to help somebody who might find this info useful ... axle ratio for open diffs OK, the easiest way I have figured out to find the axle ratio.... and its quite accurate. Other people will tell you to...
