Exhaust leaves the full length header to dual 2.25 inch with Flowmaster Series 50s.

That sounds like a V6.

yea you should go with a bigger diameter. would help take away some of that ricey sound and make it sound deeper

@saxbros On this truck, the power is coming in right as the stock torque converter is grabbing. Any loss in low end is not noticed. It may be a little more noticeable with a manual trans, but it's not all that big of a cam, and it has a choppy idle, so I would buy this cam for my truck. Mine is the red one in my other videos(300, open header).

Its a Comp 268 cam

Never took it to the strip to know how fast it is. Hard to even guess.

@1990fordf150custom This was when it had a C6 auto.

what size cam you runnin?

use flowmaster 10 series they make these engines sound awsome !!

how fast is it

@saxbros It gets roughly 17mpg, so it's better than stock. If you put this cam in an otherwise 300, you wouldnt notice much loss in mileage. I'd guess .1mpg loss.

Did the cam affect your mileage?

Did you lose much low end?

sounds mean
