If there is "no way" Ford put a flat tappet in the R's, bring some tech. I am trying to learn something here.

Did you have the cam specs for the 95 R cam? I'm sure you could tell that the duration was large compared to an equivalently lifted roller cam.

Its huge on the exhaust, moderate on the intake. (Compared to 4V cams which is all I know) Lift is a little low from what I understand. I guess SVT went with these cams to pass emissions. I love the definition: Quote:

An E303 5.0 roller cam is 220/220 at .050 with .498 lift on both int and exh. The total duration is only 280/280 as well. I believe stock 5.0 cam was about 204/204 at 0.050 and .444/.444. Someone correct me if I'm wrong.

Re: Lightning and 95 R Blocks
What I was meaning is that anyone who bought an R to race, would take the Ford cam and lifters out and throw them in the garbage, wether it was a flat tappit or roller.
The Ford roller lifter with the spider may be good for street driving and mild racing, but a real "race car" would use a cross bar roller lifter that is designed to rev and hold 8000 plus rpm for several hours at a time.

Re: Lightning and 95 R Blocks
Craig hit the nail on the head. Anybody that is going to race it is going to a different style cam than what the factory would.
It no big deal about the flat tappet. Its just because none on the 351's produced by Ford were roller so why would they do it on a 250 unit production run. It wouldn't have benefited the cost of tooling to do it. Of course it seems that a lot of racers go to a solid lift cam anyways, so that may be another reason Ford didn't do it.

Re: Lightning and 95 R Blocks
also, somebody mentioned streetability of a roller cam. Ford didn't really give a rip about streetability and larger roller cams because you had to have some type of racing license to buy the car. Somebody like me could not walk in, plop down 40k, and drive off the lot with it. You had to be a sanctioned race driver. I am pretty sure they did not do that with any other 'R' produced.

Re: Lightning and 95 R Blocks
I don't think so. They may have with the 00 model but i don't remember hearing anything about it like I did when the 95's came out
