361 bore

[TheTecher]

Anybody know how far a 361 can be bored to. I would like to get it to 4.25 the same as the 383 from the 4.12 that it is now. I am planning to put in a 4.25" stroke crank shaft also.

thanks

I would say have it sonic tested to be sure. I'm pretty sure .060 was max recomended but pistons for 361s are hard to find. 383s are not much better in terms of good ones but several more usable choices than 361s.
