Howdy, I plan to rebuild my 67' Pontiac 400 engine /4-speed (all stock with 670 heads, 4-BBL Rochester, etc.). I have a low miles engine with three cylinders with low compression /leakage. Could be lightweight top end rebuild required but I'll likely just do full rebuild.
I want to stay close to a stock rebuild but use select performance components such as new camshaft, etc. to boost HP without getting out of the CR 9 - 10 range - as the car is a weekend driver for me and I want to use pump gas.
I am considering both rotating assemblies /stroker (from Butler or Eagle) but also going ala carte with select parts such as RA IV camshaft, long branch exhaust, etc. My assumption is that going with a assembly kit will make for more complex build and be more expensive.
Any suggestions on how to approach a straightforward build without over complicating the build. I have a limited budget and do not want to get caught up on complicated specs, rebalancing, tuning, changing jets in carb, etc.
Keep here close to stock and it will be much easier to build and cost you less. Upgrading to better pistons and rods etc is a good idea but watch you don't go too far. I had a local rebiulder do the short block and I did the long block. Got good advice from Butler. Got most of my parts from them as well. Give them a call

Check out Len Williams. Seems to have a good rep and his prices aren't too bad either. I don't have any first hand dealings because I build all my own stuff. Your definately gong to need some dished Pistons to run pump gas and 670 heads. Especially with the cr*ppy 91 we have here in Cali.
I would avoid the RA IV cam if I were you, it's a 2500-6000 rpm cam, not good for street, it was a sales gimmick to sell cars, (yeah buddy you got the wild 400, but you can't drive it), stick with the 068, it's great for cruising, most of us spend our time in the 1200-3000 rpm range, plus you can't just put the RA4 cam in, everything from the springs, lifters, rockers are different and need to be up to snuff.
