        Cams

        Cams will go on with edelbrock heads and a 347 stroker kit with a 50 shot of now. Look forward to hearing them bald eagles and all that chompin.

        5 1990 GT - AnthonyTampaBay Installation Time: Less than 1 Hour

        Installed last weekend

        Installed this last week. there was some very minor rust on one of the lobes but it was wiped off with gloves on my hand with ultra slick engine assembly lube. Cam works great and is running great in the new engine. Install was very easy because the block was already outside of the car.

        5 1993 GT - FiveoJoe Installation Time: Afternoon

        Very nice camshaft!

        Fantastic idle, not too lumpy or unstable. Sounds excellent. I have a 331 stroker motor with AFR 185cc heads, and 30lbl injectors. It will need a good tune to make it nice. Backing up is of course harder than normal, but not bad. Idle is stable, but it likes to be at 900-1,000 rpms. Take offs are good, not that much different from a stock motor/heads/camshaft. Listen to the fact that it needs at least 3.55 gears. I currently have the 3.08's (will change soon). It will take off with more power than you had, but it's not a huge difference HOWEVER, once you get above 3,000 rpms, that's when it wakes up like an adrenaline shot to the heart. Best use for the weekend warrior, perhaps a little too radical for a daily driver.

      5 Top Rated Questions

      Will this work well with a Weiland Stealth intake and carb on a 331 windsor with C4 and 3.25 rear gear?

      What is the lift, duration advertized, duration at .050, and what is the lobe separation angle ?

      will this work with ported GT40X heads, 347 stroker, trickflow upper and lower intake, and 24lbs injectors?

      • These will work with your setup but you will need to check your piston to valve clearance with these.

      will this cam work with GT40X heads, Eldebrock performer RPM intake, 408 stroker, fitech EFI carb, torque storm supercharger

      • While the Comp Cams Stage 4 Xtreme Energy XE274HR Camshaft will work with the setup you described, it is designed for an RPM range that is higher than your intake will support. We would recommend the Stage 3 version of this cam for your setup.

      I have a 88 GT, mass air, 70 mm tb, 30lb injectors, sve intake, sve heads, 347, BBk long tubes. Will this cam match my components with the right springs a tune? Mostly worried the intake won't be good for the higher rpm'

      • The Comp Cams Stage 4 Xtreme Energy XE274HR Camshaft will work well with your setup, though we strongly recommend checking piston to valve clearance. A tune would be required to maintain the speed density setup with this cam. For a more dedicated street car, a stage 3 cam may be a better option, but for a street/strip car this would work well.
