SBC Tunnel Setup
I have tunnel setup on Chevy SB 400cid. 11:1 compression, with AFR heads and Comp cam 270H on a 1:6 Roller Rockers.
It's using a pair Holley 390CFM Carb. on a Edelbrock Street Tunnel Ram.
I have no problem at all with the setup. I have enough low end torqe to pull tree stumps. With 12 bolt 4:10 gears and turbo 350, with 3000 stall converter in my 69 Chevelle, it will make your hair stand on end when you hit the gas pedal. :twisted:
