4.6 DOHC Dyno Pull in a 66 F-250
This is my 66 Ford F-250 that I just completed a 4.6 dohc swap in. The engine and trans are from a 93 Lincoln Mark VIII and are completely stock. The only changes are a cone filter because I didn't have room for the stock airbox and that cats are eliminated and it has dual 3" exhaust with the cut-outs open during the pulls. These engines when new were rated at around 280hp at the crank so figuring drive-train loss and miles on it, I am pleased with the numbers. It is also un-tuned which is causing power loss as well. The truck is also running a ford 9" with 3:50 gears, limited slip and 31 spline axles. It is also body dropped 5", has a triangulated four link with bags on the back and 73 C-10 frame clip with bags in the front.
