WHAT CHEVY MOTOR IS THIS?????????????
I just bought a new racecar, and Im starting to rebuild the motor. Now heres my problem: I was told the engine was a 350 but the cylnder bore is 4.25 inches which I belive would make it a 400. The block casting number at bothe the rear and at the fron of the head flange is 3970044. I CANT FIND THAT NUMBER ANYWHERE!!!!!!!!!!!! Not in any book, catolog, web-site, NOTHING! The only info the previous owner car tell me is that it was a motor and it ran....... HELPFUL.... I've checked a few other forums where other people asked the same question but were told the engine didnt exist or that it was a 327. I dont buy the 327 aspect because of the bore diameter. If you could tell me what I have, I would apreciate it. Thanks, Dave
