Busted Block?

[hotrodt]

Building a new motor and am a little worried about the block. 1980 302 block punched .040 shooting for a conservative 300 to 350 horsepower possibly 400 with the right parts. Is this block worth using or should I find a stock bore Mexican block?

I would be a little worried about that particular block bored .040 over with 350-400HP.


Even a stock untouched 87+ block would be right at the limit with 400HP

Aftermarket block?

Have the block sonic checked, and if the machine shop says the cylinders aren't too thin, the block will support 300-350 bell hp.

Honestly if the machine work is good i dont think youll have a problem. The weakness isnt necesarily the bore's but more the very weak main webbing.
