I've been looking to run 1 3/4 inch headers on my 73 c10. Its running a 357 with a solid lifter cam (520 lift), 2.02 heads with studs, guide plates, and 1.5 stainless steel roller rockers. Never been on a dyno but it pulls really hard but I feel like my 1 5/8 inch headers and 2 1/4 inch dual exhaust isn't cutting it anymore.
Anyways i'm on a budget and big tube headers for my pickup are in the 450 dollar range! I found a set of "Speedflow" headers that are 1 3/4 inch that fit lots of bigger cars and are only 150 bucks!
My question is will these headers fit my pickup? I'm not running any inner fenderwells and have TONS of room!
Please no replies saying I don't need bigger tubes or exhaust because I know id do
