Thread: Cam Recomendation?

Tweet

I am looking for a cam recommendation for a 68 or so Chevy 350. I am putting a set of camel hump heads on at the same time, and I have an Edelbrock streetmaster single plane intake manifold and an Edelbrock 600 Carb. It has long tube headers and flowmaster 40 series mufflers with 2.5" pipes.

The motor is going into a 68 Firebird with a Muncie M-21. The rear end gears are 2.78 right now, but I do not plan on keeping them so I will gear it appropriately. I would like to have something with a little thump to it.

This is a work in progress so if there is something else in the combo that sticks out as not really being good, please let me know.

Any suggestions?

Thanks,

Josh

Need more information--what do you intend to do with this vehicle? Will it be primarily street driven? If so, then a single plane intake is not a good choice. What kind of pistons? Flat tops or domed? What cc are the heads?

You can't make an intelligent cam choice decision until you know the static compression of the motor. You must be able to match the intake closing point to the scr in order to adjust the dynamic compression ratio to whatever fuel you plan to run.

Hey Josh, why not let the experts help you? Go to the Comp Cams web site and download the FREE cam Quest software. You enter all of your info and they will list their choices. Starting with great fit, good fit right on down the line. What's neat is that they also have a desk top dyno that supplies hp/torque numbers that are very accurate. Also they will suggest lifters, rockers, pushrods, etc. All free just to advertise their products. Have fun.

I do some cruising and will be spending some time at the drag strip once I get some leaks taken care of, which should happen when this motor and tranny go in. The pistons are flat top, I do not know how big the combustion chambers or runners are, they are camel humps if that helps.

What is scr?

It needs to run on pump gas, but I am okay with buying premium if I need to. The bottom end is a 68 350, I can get the casting numbers if that says anything.

Thank you, I will try that.

The Comp Cams XE268 is always a good starting point for the 350 sbc.

The Comp XE 268 nice cam for 350. I use it in 73 Nova car turned 13.50 1/4 mile at track. Used automatic with 373 gear.
