Ls1 427? I have been reading about the LS6 C5R 427 
Can I get that cubic inch out of my LS1. Also does anyone know of a good set of heads. Thanks.

4.125 Resleeved Alum Block
4.0 Stroker Crank.
8 Cylinders.
428 Cubic Inches. 427 just sounds better so that is what I call mine. Heads are another animal all together. You need to do some research and make your own decision. Good Luck. Bear

Yes, all you need is a resleeved LS1 alum block (4.125 bore) with 4.oo crank or 6K+!!!! (Use lunati and not Callies).
STROKER HEADS, CALL MTI as the stage III LS6 heads i am running on their 427 C5R block motor which was the first LS6 heads to put a Naturally aspirated 422 C5 LS6 into the 9s (the Colonel) well over a year ago!!!

QUICKEN,
If your able to get that all dialed in plus or minus one or two other fabrications that you need to get that C5R top end to work, etc. i would say you are looking at least a 75RWHP increase over your current set up and maybe 100rwhp more if you bump up the compression with that set up to about 12.5 to 13 to1 compression! HOWEVER<plan on at least 10 to 13K to get this bad boy set up as the C5R heads are HUGE $ as well as the other top end parts neede to get this BITCH set up right!

How much are just the C5R heads? Can they be ported, or do they come
maxed out?

How do the 6.0L heads differ from the LS6 heads?
