I have read that the block is the same as the 250 chevy and the 200r4 bolts right up. engine is only missing the carb has the i4bl intake and split exhaust. shout only need to drop in and maybe make nminor changes to the motor mounts.
I will post some pics in the next couple of days. It is the 4bl sprint motor out of a firebird. the guy I got it from has the car and it decodes properly. I would be installing tonight but my carport is occupied by my friends truck his girl blew the motor last Thursday and he is swapping it.
Sounds like a great swap. I've considered it in the past but have concerns about the overall length of the OHC engine. The block itself should be very similar in length, but, I think, the OHC front timing belt and accessories increase the overall length of the engine and may create probs getting a radiator between the front of the engine and the rad support.
Please keep us updated with pics and good luck. Hope it goes smoothly.
I was going to do that to mine at one point, but parts are WAY too much for 6's in general, and especially for one that had limited production numbers in the first place. They are based on a Chevy 6 block, but there are a number of differences that I don't recall. I knew a guy with a 67 Tempest that had the 4 bbl./4 spd. combo and it ran pretty good.
I am new, Don't know how old some of the posts are, but when my Brother bought his 66Nova SS in (1975) it had the OHC Pontiac 6 cyl in it. all these years later some one told us that it possibly could have been the original engine! when that engine stopped in 1976 , he replaced it with a 1968 nova 6cyl out of a wreking yard, it went about 300,000 miles before he took the running engine out and sold the engine. we are now trying to figure out if any novas came off the Michigan plant with a Pontiac OHC 6 cyl. it may have only been a handful. if that is the case it may be an extreemly rare nova
any Chevy Guys out there know???? thanks
When you can send me some photos of the oil pan and Mesurements If they are turely the same block???? And you don't have PS.I maybe able to make the needs mods to the pan Like i have for many other 250 oil pans.
