Need a high perormance camshaft
 

Hello there everyone. I picked up this ported and polished intake manifold for my 97 Cherokee 4x4 automatic. It has a 5.3L Vortec throttle body on it. Vehicle is getting headers, flowmaster, reprogrammed computer, and an aftermarket camshaft. It sports 245/75R16 with stock 3.55 gears. I will only use it at the dunes, IT IS NOT A DAILY DRIVER! I have everything except the cam. Please advise.

If it is an auto trans, it will shift at 4800-4900 rpm and using any cam over stock will just raise the power curve to above your shift point and you will never use it. Keep your stock cam and use Yella Terra 1.7 ratio Roller Rockers.

Im building almost the same setup but mines i already have the stage 3 comp cam lifters rockers valve springs my 99 manifold is port and polished in starting my tear down friday and could you give me more info on the vortec throttle body?

I bought it off a guy that way, he had it on his daily driver and ended up going to a smaller one and smaller injectors because of the fuel. I could take better pictures though. Are you running the stock head?

Even with a modified computer?

The TCU controls the shift points and is not programmable. ECU has no control over shift points.

Yes stock head just ported it i also have a pace header going on as well as ford crown vic 4.6L injectors theyre 19 injectors but theyre 4 hole ones

Do the injectors fit right in?

Injectors fit perfectly
