Cam info please
Hello I have a 1992 f150, I’m looking into caming it with a e303plus cam, and I’m looking to get used gt40p heads to go with it. Anyone know if I’d need to replace the rods and lifters?
And if so, any recommendations?

That said, the computer won't run it without tuning. It will not drive well at all with the durations listed in the specs. And in reality, without a custom tune, you will be into the rev limiter before the cam stops making power.

Well, does it have a 5.0 or 5.8? The 5.0 will be roller so you COULD reuse the lifters. And MAY be able to reuse the pushrods.

I think he is looking at the "new" E303 "Plus" that Summit racing is putting out now. It does make decent power, but it is a light car cam not a truck cam.

Ahhh. I ran the OG FMS one in a roller 306 in my old Towncar, good torque as it has good lift and 110LSA...but very lame idle vac as to be expected. No idea what that tipped the scales at, probably around 4500lbs.
'92 will be a roller block from factory, so yes the lifters, pushrods, distributor gear, etc will need to be swapped for a roller cam swap. I would put the cash in the heads and find some mild roller cam, make good power for cheap. Old Edelbrocks, old FMS GT40X/Y, Systemax, etc and rock a cheapo HO cam. Good budget combo, bet would do an easy 225-250rwhp depending upon exhaust, rockers, timing, etc. I saw an old dyno long ago of a whopping 135rwhp on one of these in stock form. Pathetic.
I have always heard a 2.02" intake will not clear stock pistons, unless TFS style heads...anyone know for sure?

currently I swapped out my intake to the van one that lets the air come in through the grill, with a m&ms air filter.and a msd box I’m aiming for more power baby. Lol. But I’m trying to build a street truck (eventually I wanna slam it, but that’s gonna be last cuz I wanna do truck things still). And I am looking at the new e303 plus cam, because I’m not gonna be hauling things in this truck

I’m curious about the van intake. You mounted the airbox on the radiator core support? Most of us replace the 302/351 small intake tube section that draws air from between the core support and hood for the 300/460 tube that draws air from the grill. You wasted money with your MSD “upgrade.” The stock ignition system is more than capable of providing enough spark.

Before you dick with much, run a compression and leakdown to check the health of that 302. If clapped, just start with a 351W...they are still in junkyards to pluck. I see many in vans. If it comes back healthy, then I would start with basic mods.
Gear with traction device (maybe you have a Traclok and just need clutches). Full exhaust. Bump timing a hair. Fresh AOD or at least mild shift kit with large cooler, looser torque converter. HO fan or the HD cooling 302 fan. Then look into camshaft options. You are speed density, so you need idle vacuum to keep the ECU happy.

My Spark Disappeared. BTDT. Tossed the 6AL I had in the trash, spark would drop when hot.
