Boring out a early model 396

[RichBiebel]

Hey Tom....No Virginia for me. I race the ones within a couple hour ride and that's fine for me. Once upon a time I would go anywhere, but that time is long gone. I'm still treading water with a health issue anyway....good luck this year with either car you are racing.....Rich

If you've got your heart set on a 396 ,Find a cheap 454 block thats been race prepped and has worn out bores , and punch in 8 sleeves. .. Super Stock racers have been doing it for years. Illegal for Stock tho. .....Tom

No its not, been doing for many years.

Seems like every one is guessing here LOL The only true way is to sonic test for cylinder wall thickness.

Alan 20 years ago we bored them 60 all the time for stocker engines, but i think 30 as long as you dont plan on making more than 500 550 hp they are not very thick 180 or so. Good luck.
