cam help

[texas72]

I have a 71 chevelle malibu with a stock 350 ci motor under the hood with the exception of a 600 cfm holley carb, flowtech headers, flowmaster, and a rebuilt turbo 350 trans. I plan to put a comp cam in it but i have no idea what size i should put in. All i know is that i want the most hp without killing my engine.

Comp cams, 262 or lower.

[cruisenight]

Comp Cams has a line of retro fit hydraulic roller cams start there.
try to stay lower than 270 degrees duration, add roller tip rockers (or full rollers if you want to use taller valve covers) if you are running a 2.76/3.08 gear in rear axle stay with 265 or less duration. Don't be afraid to use a Holley 750 VACUUM secondary carb. It is 2 barrels until the engine demands more air. The primary side of carb is only 375 cfm. The Edelbrock around that size is also a good choice.
OR pickup a late model 1995 Chevy 350 with Vortec heads and roller cam. Good power without wild cam. intakes for carburetors are available for this engine. (1987 Cutlass with quadrajet intake?)

Comp Hi Energy 268H would be the biggest cam I'd run with stock compression ratio. I've run this cam in a 350 before and was very pleased with it. Stock converter, good power 1,500 and up.

Hi, i wasnt being a smart ass, 1800 cam help, they will answer your questions just as good if not better than us, if i was going to bild a very mils street motor id go with a comp cams roller set up with a cam in the 292 duration range with 500 or less lift.

I agree with Tech Insp. here, good choice. And Blown502Monte, no offense meant, but I have been steered the wrong way more than once by CompCams...I have also had two of their cams go bad on me, so that doesnt help. Dont forget, they are just reading off of a computer screen and giving suggestions, which any of us can do. Most of the techs you speak with dont know much about the details. You're better off speaking with a smaller cam company if you want good solid info.

Any cam suggested here, with maybe a 112 lobe seperation angle, would make a huge difference in your engine. Just dont make the mistake many do, and go too big. Like Denny said, just go 2 or 3 steps over stock, and make sure you get the right springs to go with it. Give Howard's Cams a call, 920-233-5228, talk with Scott or John.
