whats the best valve spring size and pressure for this cam? its .498 lift intake and exhaust and 284 duration i believe. i know thats the lift. and i have a 87 roller motor. with factory heads. its from a f150. and if i get different springs what valves should i get with the springs. i plan on getting a complete valve job done but i want to make sure i do it right with this cam.
also i have a 84 C4 will it bolt right up? and what stall speed TC would i need for this cam?

 

stall speed will depend on the rear gears. iirc the stock springs work with the e303

i suggest at least trying to get some gt40s the e7 truck/mustang heads suck for breathing

 

whats a good kit that is OE replacment. and its stock rear gears out of a 68 mustang. i havents gotten the rearend yet so im not sure if its 9" or 8" but its factory size for the V8 coupe. 1968

 

as for what springs to use, call up FRPP or whoever makes the cam

 

Pretty sure that the E-cam requires a 2500 stall. You can look on Summit's website for suggest parts.

BTW, if you call Ford Racing's hotline, you'll get all the FREE information straight from the techs. (800) Ford788

 

you want 2500-3000 stall.

stock springs will get murdered with that cam, look for something that can handle .550 lift or better, with around 120-130 lbs of seat pressure.

now that all that is out of the way. WHY are you dumping money into E7 heads, and WHY are you going to use a ford alphabet grind cam?

 

+1 my77. IMO, the FRPP alphabet cams fall into the category of bolt on crap high school kids get caught up in buying. At least talk with Comp or Lunati, or a real cam manufacturer. If you are set on using that cam, you need to talk with FRRP b/c only they know what the ramp of the lobes are to suggest what springs to use.

 

<~ done enough sets of heads to know what kinda seat pressure you need for pretty much anything that falls in the "streetable" catagory
