The time has come for me to repair and install my 454 Eric needs the loaner 454 back so I'm looking for a reasonably cheap fix for mine to get it back on the run stand. As you all know I'm not real happy with what happened with my comp cam and lifters. This time I'm thinking about using a summit racing cam And lifters because it's only like $120 but I'm loosing my mind trying to figure out what springs to go with and maybe that's not even the cam I should use? So let me ask you guys what would you go with in a hydraulic flat topic cam and lifters? The build is all here in the thread. In short it's a rotating assembly from a 90 V3500 stock rods and stock dish pistons the heads however are closed chamber large oval port 1965-66? 396-427 to up the compression and the intake manifold is a performer. The truck dose have long tube headers full dual exhaust th400 stock converter and 4;10 gears. I know little to nothing about what the compression ratio actually is or about spring pockets stuff like that. So I'm asking you guy's what would you go with? And what springs would you use for it? Bear in mind I cannot afford to do a retrofit roller.

I would choose whatever makes max torque at cruise rpm.
I had a Clevite cam in a 289 eons ago. It was the exact same grind as the Edelbrock Performer cam. That one never gave me any trouble and thinking back I never even properly broke in the cam. I've heard a lot of hit and miss about Comp. Personally, I'd be leery of anything short of a billet core, bit that's roller territory and my Clevite core probably didn't come from China.
Isn't Edelbrock still USA? What about a Performer? Don't they call that an "RV" cam since it makes torque? Torque is what you need for that goliath.
Edelbrock is still a US company, yes. Problem is the cores all US companies now grind off of come from China.
I may go with a lunati voodoo cam I don't know yet. I'm thinking something in the 500-550 lift range with a short duration the linotti closes the valve slower for less wear and longevity. I think the blanks are just a roll of the dice at this point. Lunati and iski still advertise quality control but do they actually test every blank? I still like the comp exe I had but I'm not putting my faith in comp again
What kind of duration are you looking at? I put a 212/218 roller cam in my dually and had to have it custom cut to get lift in the .520" range. That much lift with such short duration is tough to find and is gonna be tougher with a flat tappet cam I suspect. I went through Schneider Cams and had a great experience. They split off of either Comp or Crower way back in the day and are a very legit operation.
