Thanks for the info. That dyno sheet is interesting... what does it look like below 3900? Did you start your pull at 3k or less?

There's still 492 ft-lb at the bottom of your sheet, that will move my A-body on the street without going to 7K on every shift smile

What do you mean about using a borescope? I assume there'll be soot from reversion? shruggy

This project really won't see much use, just a little "Saturday night special" driving and maybe an occasional trip to the strip. I figure the bottom end will be soft but the higher I spin it, the more power it'll make. At least someday when I get better heads. Besides, I can always change cams if I have to.
