Depending on how much the SBC is built, the 2800 maybe too much. I have a 700r4 with a 2000 stall with a 383 around 400hp.....Nothing earth shattering but i am a cruiser going up and down the coast to car shows...I used the existing cross member but had to modify it to fit, probably been easier to just buy one.....At 70mph, im only turning 1850rpm
