? What to do What to do 327 vs 396? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Custom 68 · 04-28-2002, 08:29 PM

I know this has been talked about several times but my story is different. I will try to make this story short. About 15 years ago I bought a running 396 I don’t remember what all I was told but it doesn’t matter. I took the 327 out and dropped this one in. I finally got it running right or at least better only to gernade a piston. It of course died or was shut off immediately. It put a gouge in the cylinder wall when I opened the oil pan it had antifreeze in it. Anyway I got it from my folks over the weekend and ran the number to find out it is a 402 out of a 72 pickup. The guy I got if from had it in a nova I think. Anyway what should I do? My 327 runs pretty good. Can this be sleeved and will it work have you ever done this?
Just wanted to share a story and a question from my youth.

Thanks!
Dave

Slap the small block back in, and take the time to do the 402 up right. You might be able to rebore it, may need a sleeve. You'll never know untill you rip it apart and take it to your machine shop.
