Horse Power and Torque

My 68 Barracuda, with a similar combo, just with TTIs and OOTB Eddies, running 10.9SCR went 106@3650pounds. That calculates to about 350 hp. I drove 2.5 hrs to the track with 3.55s, made one run, and drove 2.5 hrs back, on 245/60-14s lol.
So my guess is; if you put long-tubes on that 360, then you'll be at about the same power-level, barring detonation.
The 360 loves that 268* tho, with your cylinder pressure. That combo was my favorite. Ima thinking your torque will be a lot higher than you imagine,barring detonation.
My timing was 28* at 2800, and 32/34 @3400, and with aluminum heads I can run 87E10 on that. Yeah I know I'm leaving power on the table, but it spins new 295s to long past the speed limit so what's the big deal,eh? I loved that combo!
Try to keep her cool.
