SBC TPI 383 ways to reduce torque

[nilak]

Something is way off in your dyno sim. Mine peaked at 5,200 in hp and about 3,500 in torque.

Did you run it with headers or with a stock iron manifold? But yes, it still seems off. Can you gain 144hp only by installing large headers and removing water pump, alternator, smog pump?
With the tpi, although it’s made for torque, it can still make power, obviously it’s not optimised for my application but it can still do the job I want if I can get it to 350hp.

LONG Thorley Tri-Y headers (collectors equal with the trans mount crossmember on the 700r4) and factory GM true dual 2.5" exhaust with a X-pipe added. The exhaust was factory from under the driverside middle passenger seat where I added the X pipe to the tailpipes. Then I had my local muffler shop bend up 2.5" pipes to connect the header collectors to the X-pipe.
