Building a 460 for my F250 to pull my 8000# car trailer. Not a hot rod motor, I want something that will pull my trailer effortlessly at 70-75mph (3:55 gears/T18) and give 8-10 MPG.
What I have so far;
1973 passenger block/crank/rods
GM style HEI (Proform)
Flat top pistons
"Pulling" cam (comes with the engine kit).
I traded for a Weiand Stealth intake. Would this intake be beneficial or should I re-use my cast iron one? Weiand says it makes power from idle to 6800, this engine will never get over 4000rpm, cruise around 2800rpm.
