- you're right, and if i had thought about it i would have realized
- that .060 (which is pretty much the limit) over wouldn't give 383 cid.
- i actually meant "bored and stroked." sorry for the brain fade, and
- thanks for the correction.
-
- after your post and somebody else's post, though, i'm wondering if
- the 383 involves any boring at all. is it just a matter of dropping
- in a crankshaft from a 400? (car and driver says it was bored and
- stroked.) also, wouldn't the longer throws of the new crank result
- in greater side loads on the pistons? would this reduce the redline?
