Maybe at the flywheel, not to the wheels.

Stock at the flywheel is 101hp i think. So maybe about 85 - 90 at the wheels. I think the header and intake would probably give it about 15 more hp at the flywheel. Its a noticable increase.

Yeah, you'd notice it for sure, especially once it starts to rev a bit. I'd say 120Hp at the flywheel.

how is it only 15 more at the flywheel if RB is claiming 20 with headers and 40 with intake and headers.
It doesnt seem worth $1000 for 15 HP

get a used one for cheaper
I got a used pacesetter (under rated) for 60$
I made my own exuast tho, which I doubt you can use, 24" glasspack with a downturn
keke
but you can find componets more sane

as for the carb 300$ will get a sterling or banana

with rb header, 2.25" high flow cat, same size pipe, and a dual 3" tip muffler, i dyno'd my stock port 12a @ 107 hp to the wheels, and i think it was 96.1 torque if that helps any
