Any specific camshaft/intake/carb setup recommended?
The engine is a 1993 SBC 350 out of a Pick-up. Right now, I am converting it to a carb set-up with a Elderbrock 600 CFM carb and Elderbrock Performer RPM intake. I'm also adding a set of headers. The rest of the engine will remain bone stock. There are so many different cam profiles available, I'm not sure which one to get! Once again, any help is greatly appreciated!

Ok, a lumpy cam sounds bad. It will make it harder to take off from a standstill. But the light car is easier to get moving. You will never need a high reving play toy on the street. A stock roller cam motor is rev limited to about 5800 rpm at best because of the heavier valve train (stock roller lifters). I know a 97 vortec was a roller cam motor but I don't think the 93 was. I think the vortec was the first in trucks. Believe me tell the cam mfg exactly what you have to use. Compression ratio, carb, and intake. He will tell you what is best, believe him. Thats not a vortec motor so it's pretty low hp stock but will have good torque numbers probably and was more than likely built more for emissions than torque. A reasonable hp figure with a small cam and the stock heads would be maybe 300 hp at the crank. Higher compression will need good gas. I'm kinda dumb on the location you have posted so not sure of the summertime temps for air temps you will be using.
If you are on a budget use what you have and leave the cam alone. You still need a dist get a good one. |

You still need a dist get a good one. The land of ID is the Boise Idaho area. I found out that the engine is a non-roller with 9.3:1 CR. I called Howard Cams and they recommended a cam with .449/.449 lift, 290/300 Adv Dur, LSA of 112 and an RPM range of 1600-6000. I'll be running this with a Victor Jr. intake, a 650 Carter carb and shorty headers. Is this a good combo? Not sure how they do it, but Howard Cams also has a cam that has .390/.410 lift (less stress on the stock valve springs), 296/302 Adv Dur, LSA of 114 and an RPM range of 3200-6400. This would seem to be a better match to the intake manifold and it would definitley move the RPM's higher up...may be too high? So should I go with the recommended cam or go with the one that I think would work better in the car? Am I missing something here? (IMG:style_emoticons/default/huh.gif) |
