What's it gonna run

A buddie of mine has a 69 Barracuda. Engine is set up nearly Identical to yours. His has caltraks and is mini tubbed, runs slicks. He runs consistant low tens 10.15 to 10.26 without juice into the 9s with. Started out with higher stall speed dropped it to 3500-3800 lap times decreased 60 ft improved. The torque band (at least in this case for sure and seems to be the case with SB strokers) starts right about there. Lets the engine hook up and pull sooner. Seems with the higher stall speed it was wasting torque. From the passenger seat the higher stall was like hey that sounds good and this is fun. When he lowered the stall speed it was like WHOOA YAA soon as it hit 4 grand and just kept pullin from there . He runs 4:56s and RPM ceiling as limited 7500 RPM shifts at 65 to 68K.

Gave him a call to confirm this stuff and had to listen to him go on about troubles with his 727 sprag his soon to be ex BLA BLA.
