Cam Question

Cookston60 · 10-08-2009, 10:57 PM

I have a cam question. I am getting ready to put a 305 tbi in my 4.3tbi s10. We are taking the 305 .30 over with flat top pistons. What kind of cam should I use? I am looking to get the motor to have a nice deep sound. My grandfather is helping me build the motor. He has built tons of carb motors, but not many fuel injected engines. So, he wasn't 100% sure on the type of cam to use. Thanks in advance for all of the help.

A whole lot depends on what it is you are trying to do with it. And what other parts you will be running.

The motor is going to be pretty much stock other than cam and taking it over 30. We are going to rebuild it; it is going to have the stock heads with a new valve job, stock crank, .30 over pistons, a new cam, and maybe some bigger injectors. That's all I can think of right off. Let me know if I left anything out that needs to be added.

TBI doesnt allow you to use many cams. for example...Comp Cams only makes 1 TBI cam.

I would put a carb on it, maybe even swap to TPI.

I am going to keep the tbi, because I don't want to have to change out the wiring harness. I will check with comp cams and see what kind of cam they suggest. I appreciate all of the help.

Call the summit tech line and ask if this cam will work for you... The summit part number is 1103.. I use this on my carbed 327. Has good low end torque and pulls real well, best part is you can use a stock converter, so I think it will work for a tbi setup.
