how much better is this cam:http://store.summitracing.com/egnsea...+115&y=14&x=40 than my current one:http://store.summitracing.com/egnsea...00+115It's a remake of the 57 corvette Duntov cam.

 

Better for what?

 

improving my engines hp and torque. The cam is a big step up over my current cam. Currently i have .218/.224 duration and .462/.469 lift @.050This cam is .239/.246 duration and .483/.477 lift @.050.

 

Those cams aren't even in the same ballpark. Okay, well, maybe same ballpark, but a huge step up. Chances are your current engine if it has that cam wasn't build to support the airflow or the RPM required to make use of the larger cam. Not to mention the whole rest of the car.

Maybe you could share everything that's been done to the car that isn't stock as well as the complete specs of the current engine?

 

alright. Chevy 4 bolt main 350 bored .030 over. Eagle steel crank and Eagle Ibeam rods. Sealed Power tri-metal bearings. Keith BLack flat top forged pistons, i mentioned the cam, 461 Camelhump heads ported and polished with Manley Stainless valves, 2.02/1.94, Comp roller rockers and Hardened pushrods, Edelbrock Torker intake, Holley 650 dp 4150 series carb with choke tower and air horn removed, 220gph fuel pump with aeromotive regulator, 3.73 posi eaton rear, Stage 2 turbo 350 with b&m shift kit, alto clutches, kevlar bands and hardened sprags and a fewextra clutches and other goodies. Anything else you need to know?
Oh, i forgot the Milodon Main caps
And the 3000 b&m Stall. Suspension is all poly bushings with sfc's and boxed controlarms and panhard.

 

hey cool i made Senior member!! Go Me! THanks TGO!

 

i have a 350 tpi ported plenum shift kit what size cam would be best to put in being stock?

 

I would say stick with your current camshaft or upgrade to a hydraulic roller with similar specs, unless you're ready to change several things on the engine & car to match the larger camshaft.

Upgrading to a hydraulic roller with similar duration but higher lift numbers would likely increase your power across the board without having to upgrade you heads, intake, and gearing. You may only need valvesprings, retainers, lifters, and pushrods for the upgrade.

 

This will work well with what you have, but it's always better to get a custom tune after a cam swap. You will also need to upgrade the valvesprings and retainers to prevent mechanical interference problems with the added valve lift. The swap can be done without pulling the heads.

Something like AFR / Trick Flow...probably looking around $1200 - $1500 for the pair.
