I'm in need of some advise on my selection of a cam for a engine i'm working on for a camero here's the specs it is a 10.6to 1 engine with alluminum dart pro 1 heads with 64cc chambes with 215 runners and 1.6 rocker ratio, eagle 4" crank, eagle 6" rods, victor jr short intake with a 850 willys mech secondaries, i am looking for info on a roller cam and this will be going in a 85 iroc camero 3.73 rear and will have a auto tranny with a stall converter, thanks for any and all help

How heavy is the car? How fast do you expect the car to go? Do you have a converter and if so what stall?

dont know the weight of the car its not gutted just as it came off the assembly line, i dont have a stall converter bought yet but benz this is something i will be driving on the street i would say a 2500-3000 stall and i dont care how fast it will be as i know it will be fast enough to get me in trouble, i basically want as much camshaft in it as possible but still be able to drive it to town and cruise around on the street, i know it doesnt have enough cylinder head on it but its what i had laying around any info greatly appreciated!!

Here is a Comp Cams hydraulic you can try, but the nice thing is with a 400 it's hard to find a bad cam. It will work well with an 11" converter in the stall range you listed. Your heads are actually a little large for the street, but not excessive. It should easily put you in the mid to low 13 second range depending on your weight.

If your budget will handle a hydraulic roller, this one should get you in the 12 second zone.

I was sure hoping to put more camshaft in it than that but thanks for the info

More cam requires more converter or it will leave like a pig. What are you looking for?

flight71 11-26-2008 02:26 PM

well it will be a solid roller benz i already have lifters laying around but i guess i just thought maybe the big cubes would allow me to get away with more camshaft, i keep referring to this car as a street car but it will only be something i drive to town on occasion so just wanting to take the words "street car" to the limit. I also plan on putting a NOS cheater plate system on it also but will keep it down to a 150 tune up, just looking for a bad ass play toy to drive on the street. I used to have a 78 malibu with a 355 10.1 crower solid lift cam around a .530 lift i believe with a 350 turbo 2500 stall 4.10 rear with a 200 shot on it and i just miss have a street car, man was that thing fun to drive, not a terribly fast car, just real fun to drive and thats what im looking for i just think in the 8 years that have passed since the malibu that some of the race toys i have now might make it harder to find something so mild as the camero a bore so just looking to sqeeze all i can out of this cheap little toy, thanks for any help

With an 11" try this.

With a 10" 3500 to 4000 stall this one will scare you.

I wouldn't worry about that much stall on a limited street engine, make sure your valve springs will handle the lift.

Now thats more like it! Any advice on a converter i've only used tci and coan and really good luck with both but were all in all out race applications i had an old GER converter in my malibu that someone gave me that worked awesome but didnt know anything about it, thanks for all the info
