Best Roller Cam For a 351w? NEED HELP!!
 

351w Short block
stock 5.0 fuel lines
trick flow twisted wedge heads
trick flow "351" intake
24lb injectors
pro-m 77mm mass air
trick flow 1.6 Rocker arms
crane hi-6 ignition & ps-91 coil
190lph pump & AFPR
Stock 5.0 t-5 (when she blows, probably a Termec TKO)
bbk 70mm t-body & egr
3.55 or 3.73 gears
drop engine mounts
new flywheel
new distributor
new (or used) oil pan

NOW FOR A CAM, IT WILL BE A ROLLER CAM, HOW MUCH LIFT COULD I HAVE WITHOUT PISTON-TO-VALVE PROBLEM?
I want to stick to the trick flow name if possible & was wondering if I should use

stage 1(Duration@.050 221*/225*, lift.499/.510, Lobe seperation 112*)

Stage 2(duration 224*/232*, lift.542/.563, lobe sep 112*)

or stage 3( duration236*/248*, lift .574/.595, lobe 110*) cam?
I dont want to cut the pistons, but might get 10-12:1 compression pistons(dont know what the stock 351has?) also for pushrods I have no clue.
I will use the stock 351 until funds grow, with the exception of fuel injection, but with the stock 5.0 19lb injs
If you can suggest any other things missed.

thanks!

You need to decide what compression you're gonna run BEFORE you pick your cam...if you're running 9:1 the tfs stage one aint bad...neither is a e or f 303

Sorry to rain on you're parade, but neither of these cams will work in a 351. The 351 was never offered with a roller cam and lifters so all of them have short lifter bores for flat tappet cams. You will need to have a custom, small base circle cam made for you're application and purchase a roller cam conversion kit. The stage 1 TFS cam is not agressive enough for the heads anyways. It is also a dual pattern design which is not needed because the TFS exhaust ports flow very well, within 80% of the intake i believe. A dual pattern cam is not needed unless you drop below about 75%. A better cam would be around 225-230 duration at .050 on both sides with around 550 lift. To use this much lift though the pistons would have to be clearanced for the valves. Without doing this you're limited to about 520 lift (depending on duration) with TFS heads because of they're altered valve angle. You're best bet would be to talk to a performance engine builder and have them help you select a cam for you're combo.

haha..sorry to rain on your parade, but whats a 94-95Lighting(amunst many other cars and trucks) got them..and you can retofit any old 302 or 351 to take a roller cam with a simple kit..also they still make a 351 roller motor right now..its called a Saleen S351..infact i think the 351 sportmans block is setup for roller
