and will this work http://www.summitracing.com/parts/FMS-M-6268-A302/ with http://www.summitracing.com/parts/CRN-364761/ with http://www.summitracing.com/parts/CRN-99280-2/

Anything i need to change before i start ordering parts? total of $1400 add the $250 for the intake and I'm only $100 over my budget. Not bad

Valve spring part numbers are for 302 heads. Will post correct numbers for 351 head, but have to get some sleep right now.

Dano61 I would get a build sheet for this motor before I started buying stuff for it.
20 some years ago Yates racing had a build sheet for this motor with the special intake you needed to use for the Cleveland heads. Also I would have the pedastools for the rockers ground down and drilled to accept screw in studs and guide plates.
The stock pressed in studs will pull out at the high rpm's you are talking about.
I learned that lesson first hand when some push rods came thru the valve cover because the studs pulled out. I was lucky they did not go down instead of up.
They don't have to pull all the way out either, just far enough to let the push rod escape from it's seat. Then it's just the luck of the draw sorta speak.
Kurt

I agree with Kurt. This build scares me. Anyway, here's what I came up with.
96870 spring, 351 head, should rev to 7600 with 351 valves
99969 retainer (this is steel, I'd probably research titanium)
99094 locks
99820 valve stem seals
27750-16 Gold race rockers, 1.73 ratio, requires 7/16" rocker studs and guideplates.

This is the description of the 302 solid lifter cam from my Crane catalog...
3600-7400 rpm power range, 248/258, 310/320, 108 LSA, timing events 21/47/62/16, lift 0.533"/0.555", hot lash 0.022"/0.022", Performance useage, good mid-range hp, bracket racing, auto trans with 4000+ converter, 11.0-12.5 compression ratio advised.

Call up the guys at Crane and discuss all this with them. They could have an alternate plan for you. Also, some of the members on this board could have an alternative plan. I'm sort of flyin' blind on this one because I have never put one of them together.

Here are few tidbits that might help you..........
