I found a 230 engine in an older chevy van, the type with the engine in the middle. I thought it was a 250 but according to the head numbers its probably a 230. Could only find 4 numbers on the head. The numbers are 4437. The block is the common 3850817 which could be either. I went to
www.butlers-a1.com and found the casting numbers. Anyhow, I did a compression check and it evidentally had an overhaul. The cylinders hot with wide open throttle is as follows...170, 165, 165, 165, 170, and 165. Thats really good for those old stovebolts. It runs smooth and idles smooth. No "funny" noises or cold sounds and no smoke or blow by. All the plugs were dry and no oil on any of them. My question is since I can get this engine at a good price can you make it run like a 250? I was thinking of some headwork, roller rockers and a modest 4bbl with HEI and the MSD I already have and 3" Magnaflow which I already have in my 87 full size pick up with a 700R4 and 3.73 axle ratio. I would like some ides or opinions please. Hard to find the older 250s ( non integral manifold ) in good shape that don't need rebuilding or a valve job at least. Thanks Henry
