as far as cheap "white box" cams go I believe Elgin has the longest list, and usually you can find them at the best prices. They have all the cams Summit offers as their house brand plus a few more. You can download the Elgin catalog and find the closest one to fit your needs. Some of the prices vary but its usually 60-70 bucks for a cam.

Elgin Industries

They also have great customer service in my experience. I've used various products of theirs in the past as they have respectable quality and damn good prices. I will be the first to say they are NOT the best around, but often I don't need nor want to pay for the best.

I have used lots of summit cams and never had a problem. In fact, less problems as compared to the compcams that I used.

I recommend to error on the smaller size. A cam in the 208-212 degrees at 0.050 on the intake and maybe 214-218 on the exhaust, and 110 lsa. A 327 with 3.08 gears and a stock converter calls for a small cam.

I would get a regular RPM intake (not air gap) with a square bore and get a 750 holley 3310 which is also square bore. Plan on changing the front jets to 69's or 70's as 3310's come jetted rich.

Edelbrock/carter carbs are terrible. They tend to vapor lock and the accel pump seal grooves the cylinder which makes the throttle sticky.


This cam looks good (see link below). not a summit cam but is between the summit 1102 and the 1103

I would go even smaller if it were my car, like the summit 1102, but I may be overly conservative on cam size as i like low speed response.

For a basic street driven car I couldn't disagree more. For that application you won't find a better carb. Basic street driven cars are the one area where Edelbrock carbs blow away the competition.

Make it more of a nasty racing engine and they quickly become a pain in the *** though as they are more limited in tuning than your traditional holley.


Edelbrock carbs do have one major fault though- the throttle shaft bores can wear out over time (especially with excessive return spring tension) and there is no quick and easy fix. With a holley you can just swap the entire base plate when that happens.

This thread is a decade old. Hmmm where was I 10 years ago?

I have owned two of those edelbrock carbs and threw both away for the above listed reason. Pure junk of a carb. Undrivable on the street in my cases. Vapor locking and sticky throttle due to a poorly designed accel pump.

I've had a few of them as well, replaced a few holleys with them as they are stupid easy to work with and tune.

Where you're clogged? The air bleeds can clog if you get ****ty gas. Any as with 10% ethanol will help keep them clean though.

Damn good street carb, except for the throttle shaft issue.
