Hey Double Duce - if you're out there - re; my last post:

"This would require a taller rear end (3:90-4:11) and probably a 3000RPM stall. "

Should be:

"This would require a shorter rear end (3:90-4:11) and probably a 3000RPM stall."

Small numbers = "tall gears"
Big numbers = "short gears"

Us old people sometimes get our fingers in front of our brains!! Fortunately we've got friends on CHR and we look out for one another..

Also - make sure those steam holes are drilled on 400 SBC applications - see:

Keep us informed!
