good cam choice for 350...
« on: May 22, 2011, 07:37:26 PM »
Just want everyones opinion on a good cam for my 350. Its in my 76 3/4 ton 4x4. I want something with good low end grunt but want to keep the engine virtually stock for now. It currently has a performer EPS intake with edelbrock 650 thunder avs carb, msd ignition and long tubes. The bottom end and heads are stock and I would like to keep it that way for now. A buddy suggested a comp cams xtreme energy xr268 with a set of valve springs. Any suggestions?

Why don't you want to update the heads?

Basically just to keep the cost down. One day I plan on doing the whole engine but for now I want a little more bang for my buck.

It's not really worth going with that cam and stock heads. It's like heavy breathing into a paper bag ya know?

Like vile says I would hold off until you are able to do the heads, shop around for a deal.

If your using stock heads I would use a cam the complies with the limits of the stock valve train as well. I dont remember what model my cam is but its a comp cams and it was "the biggest cam I can get with stock valve train". Ill grab the receipt when I get home from work. Its got a great rhythm and throaty sound from the duration. My idle sits around 550-650 depending on temperature.

How many miles? I have no idea. The truck has almost 500 000kms on it. The engine isn't original it was dropped in with a fresh rebuild about 4 years ago. According to the guy I bought it off anyway. My intended use is more low end power with a noticeable idle. Not really sure on a budget until I do mote research.  C20 if you could find that cam that would be awesome! Thanks.

I really like the cam. Make sure you buy cam and lifters because if you use a new cam with old lifters youll flatten it because of the different chemical properties. But i would definitely recommend it. I should be home in an hour or so and ill get the recipt. I think its a 460lift 240 duration, but I dont remember

This is the best bang for the buck and about as big as you can go with stock heads...

Those two cam profiles are an intresting comparison of a single pattern and dual pattern camshaft's. Ive always believed that a nice dual pattern is the way to go. but ive met allot of folks who use a single pattern. I know the best way to wake up an old ford fe engine is use a dual pattern cam to help the exhaust scavenging. the fe heads have a poor exhaust runner design.
