Realistic estimate Please

Oh, I forgot my car was a 273 2bbl when it was born, so it does have the cable type accelerator peddle.

on the lift it helps if you have an engine sling, to adjust front to back load.

I have a "Thingy" that you can crank to tilt the motor front to back, is this what you are talking about?

Concerning your SB 904...make sure your slant six converter is the same era 904. Pre-'68 904s had a different input spline to the torque converter than the '68 and up. A '68 and up tranny will have more upgrade options for a torque converter than pre-'68. As far as stall goes...the slant torque converter will flash a little hirer with that new found power in you 360.

What are some Key identifiers of a post 68 904 vs an Early one?
