Sounding like good news so far for me. I don't see me cracking 600HP, or probably even 500HP, all depending on cam/turbo, etc.
To give you some pictures of what I'm playing with:
That is a 292 crank on the left and my 250 crank on the right.
And the Pontiac 230/250 have a deeper skirt around the mains.
I've thought about going to stroker route, but because I'm going with forced induction to gain more rpm (in theory) I think the comprimises needed for the additional cubes aren't benificial enough and will likely just stick with the 250 crank. There is oil baffle clearance issues as well with the 292 crank.
Keep the crankshaft info coming! Thanks guys.
