H - PIPE

I really missed the off-idle torque, when I cut mine out to fit the GVod. I mean, it was a shocker!,lol.
My car is a 68 Barracuda with a manual trans and I am running a 230/237/110 cam at 10.95 Scr ~180psi cylinder pressure, and the TTIs.
So after a lotta tuning work,and not getting it back;my cure was to just install the Commando trans gearset with the 3.09 low. That gear is a 16% improvement. I'm not saying that the H was worth 16%. Just saying the 16% more starter-gear did the trick. Now my 3.55s take off like 4.12s...... in first gear anyway.With a clutch car and 3.55s I spend a lot of time below 2800, which is 20mph in first/33 in second/45 in third/ and 63 in fourth, and in OD, 65=2040 rpm. So I missed the torque all the time, when just put-putting around. I like the 2800 shift for the happy sound the engine is making, and it's just starting to wake up.
If you are running an auto and more than about a 2800stall, I kindof think the crossover would be a waste, for anything but cruising.
I have dual 3s front to back. No problem snaking it to the bumper.With 3.5s tho, it might need a lil pinch as it goes by the LH rear spring hanger. Otherwise the 3s have plenty of room. Even at lowered ride height.
The H-crossover was not 3". I didn't measure it. It mightabin 2.25 or perhaps 2.5.
