this is true , and gm and toyyoter copied them , because neither ever produced a canted valve small block head , i do wish some one would answer the original question about T-mac,s engine , got my curiosity up...........Originally posted by Forward Bite View PostYou are over simplifying. Ford engineers design the heads Ford Performance sells. The D3 head is an evolution of the Cleavland production head.

Better take a look at what is under the hood of the top dirt drivers using Fords. D3 heads are outdated technology. I don't think you will find them used by the top teams.Originally posted by minthess View PostActually you can buy the Ford Performance D3 heads dominating the sport on the Rocket house cars through any Ford dealership parts department.A droop rule is like infield tractor tires, everyone knows it's stupid, but they still keep doing it.

Too much on engines. Ask Overton who is running a borrowed engine from a builder most haven’t heard of. Racing is balance and tires. Engines builders are overrated. If you can’t get 900 hp to the ground what are you gonna do with 800? Get your chassis, shocks, balance and tires right and your a winner!

I looked under the hoods of B Sheeps , Bronson, and Josh Richards cars last year and they were using D3 head Ford engines. According to the last issue of Speedway Illustrated , T-Mac ran a Pro Power 454 cube Wide bore Dart Chevy last year. If he has a Pro Power Ford this year , Pro Power must have found something they liked about the Ford.
