[SOLD] 70/71 HP Big Block Exhaust Manifolds 550.00 or BO

[Mopar Fred]

I have a set of 70–71 HP big block exhaust manifolds. They are new. They have only been ran one time on the Dyno to compare against headers of my recent engine build. I bought them from Tony’s parts again. These are new not reconditioned. I am asking $600 and the cost to ship them. I will take payment through PayPal friends and family.

How about a headers VS manifolds hp post? I would sure be interested!

I will be glad to make a post about that. I only have the Dyno sheet that shows running the headers not the exhaust manifold. I was not there personally when the engine was on the Dyno. My motor is a 383 stroked to a 435. We were able to get 435 because his bored 40 over. a 440 crank and 440 length connecting rods it has a 565/565 roller cam @50 237/242. With the headers the motor Dynode 555 HP 574 Tq with the exhaust manifold it Dynode 460hp I am not sure of the torque.
Chris at performance injection equipment in Delaware built the motor.
