FWIW I have a 94 roller block that I have bored and stroked to a 408. Should be around 500 - 550 HP (depending on what heads I use). I have that Canton main support girdle but no valley girdle and I plan to twist it up to 7000 - 7200 RPM's.

My stock block 408 goes 9.80's on a 125 shot. It is a roller block no girdles top or bottom, hydraulic roller, and I'm not sure how many horsepower. Shift at 6600 rpm.
That's what I figured. So I'm trying to figure out what I want to stroke this motor out to. I realize it's not going to be hard to pull about 450 hp out of this motor. I'm thinking 393, 408, or 427. Any advantages or disadvantages to any of these?

Agreed. 0.060 over was just a little too much for me, and after getting the 408 kit in and looking at the bottom end, I'm glad I didn't. even with the 408 there isn't much piston left in the bore. 393's go real nice too, I wouldn't be afraid at all of putting one of them in.
you dont seriously buy into that "valley girdle" bull****... do you?
I do depending on what you are running. I have seen more than one block cracked in the lifter valley. That being said I did not put one in my engine. It is extra insurance if you are pushing the limits.
If you are going to install a roller cam you must make sure it is a retro fit roller cam. You will need to get a roller cam installation kit along with tapping the block in the lifter valley to install it. Its not a big deal, you just have to be aware of it.
CCCharleston, your car goes good! gets some good traction.

fail fail and more fail....
no machining needed, no tapping, no installation kit... link bar roller lifters and a STANDARD base circle roller cam are ALL thats needed
