Thanks but I know what a pushrod is. I made that statement as the title because Ford has not had them in gas engines for awhile. Some here may not have even been around when Ford had them in pickups and Mustangs.
Sorry for any confusion.
I think Ford is taking advantage of the reduced emissions requirements that our wise President Trump has done for us and the good of the country.
Port injection, pushrods etc. Big engine decent hp and torque and cheaper to make than the overhead cam engines they adopted in the 90’s.
