Will you be having the heads cc'd and the true compression determined? I'm curious to see what the actual compression is with those pistons. Since the 8.4 listed in the books for the flat tops is more like 7.9, or 8 as mine was.
Also if the compression is an actual 10.5, you could mill the top of the domes a little to get a little less for our gas.

What heads are you using, and did you decide on a cam?

Sorry about the hi-jack.

I probably wont cc the heads. The replacement pistons are 10.25-10.5/1 and with composite head gaskets instead of the factory steel shims the final compression should be around 10:1. 93 pump premium should run fine with that.
I got a Isky E-4 cam. (#390144) It's a solid lifter cam with .425 lift, 216 deg.@ .050 with a 108 deg. lobe center. Its a bit bigger than the stocker but has a slight lope to it which the stock cam doesn't. Mike
