Better off without Ford letter cam?

[Rob Shackleton]

It would be a lot of work to gain 10 hp or so from a custom cam. My old car went 10's with an E cam. My current car has the E cam as well.

Thanks guys. I;m not ready fr a new set of heads or motor yet. Maybe in another year or two. I guess I'll wait till then and go w/ a custom grind then.

Hi,

I would say for an off the shelf cam, to use either the TFS Stage 2 or the FMS F303. Either one will work very well for your combo. We have used the F cam in lots of cars, and I think for it's no hassle install (usually never any P to V issues), and it's fairly cheap price (like 200 clams), it's great all around blower cam. I've personally seen a car make 550 RWHP with one, and know of someone who made 580 RWHP with one.

About your heads, for what it's worth, I made 546 to the wheels with our of the box Ed Performer 5.0's (1.9/1.6 valves, old style, not the new ones), using 15#'s of boost and a dual pattern cam favoring the exhaust (Wolverine 1087, 112 lobe center).

Good move stepping up to 42's. How much boost are you running? Unless you're running low boost, or maybe running lean with those 30's, then I'd say you have more HP in your combo just the way it is.

Hi Jim. Thanks for your help.

Currently I'm seeing 10# of boost w/ the 3.25" blower pulley and stock alt pulley w/ the 30#ers....w/ a very conservative tune. Once we threw the 3" pulley on, the car ran WAY lean from idle and it just got worse from there. Once we swap the 42's in and move to either the 3" blower or 8" alt pulleys I'm hoping to see 12-14's and get 425rwhp+.
