350 Cam Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ClassicRedneck05 · 11-20-2006, 04:12 PM

Can anyone tell me the best cam for my 350 its stock right now but i want to put the best possible cam in it without aving to change the torque converter or any lifters and all that basicly just the cam any ideas on a good radical lopy sound one?

Most everyone around here recomends the Comp Cams 268H. You really should replace the lifters too. They are supposed to wear in together.

Also that cam will work alot better with an intake, headers, and dual exhaust. The dual exhaust is a must at the very least with some kind of 4 barrel intake manifold. Just not sure what you are running right now???

The guy to ask about a cam is at the cam grinders.The tech line will ask tons of questions.They will want to know,tranny,reargear,tire size,comp ratio,driving habits,weight of vehicle,ect.These guys match cam to use all day every day and have tons of experience and real world use to go by.However I thinjk the 268 suggested above should be in the ballpark.Just remember that unless you lmatch the rest of the combo your performance may not improve and may actually be worse.

also have a holley 780 thats needs to be rebuilt but i dont think all the parts are on it right now i have the quadrajet carb on it and stock intake but i have an edelbrock performer intake that needs to be cleand up

That Holley 780 sounds too big for a 350 street engine. If your performer intake is a spread bore just use it with your quadrajet. There are ways to hop up or richen the quadrajet.

PanelDeland is right though. If you want to do it right you need to talk to a cam techline. and tell them what you are looking for.

What year model truck are you working on? Do you know the rear end ratio?
