Description:

Up for sale is my old top end specced by Greg Good for a 4th gen F-body. Top end has been replaced as I have gone to a larger ci motor with LS7 ports. The setup has ~1500 miles on it. The heads are PRC247's that Greg then went over to make perfect. Lightweight hollow intake valves and stainless exhaust valves. The heads do have Greg's parallel cooling modification done.Rocker arms have a Straub bushing kit installed. Intake was port matched by Greg to the heads so would ideally like to sell as a set, but I am willing to split to the right buyer. The camshaft was specced to eventually add some nitrous, but I just never got around to it, cam specs are 247/259 .649/.649 115LSA. Setup sounds very healthy at idle and at WoT. No concern for lack of lope even with the camshaft being on a 115LSA. I will also include the 1x double timing chain and adjustable crank gear and pushrods. Car went 132mph @ 3500lbs in the 1/4 with a mediocre tune-up the one time I took it to the track.

Some videos of the car with the head setup.
