Default LT-4 intake manifold?

What kind of results do you get when you you put on an LT-4 intake manifold with cam on the LT-1? I am thinking of doing this, is it worth the money?

You need to make the heads match with porting or swapping also. Intake and cam alone is only half the work.

And also what cam should I look into that seems to be best for staying All Motor?

What kind of motor/car do you have. The LT1s don't have a separate upper and lower. :confused:

The LT4 manifold is not a direct bolt on for the LT1. The ports won't match and you will lose performance.

Thanks for the Info, do you think it is worth porting the stock parts? I have an LT-1, I was un aware about the manifolds. Info helps a lot. :)

Oh I don't know how much power do you want? I've got stock parts ported and make 100 horsepower over stock for a total of 365 at the rear wheels. Think that would suit you?

I was told that just porting the Intake manifold would give me minimal gains. Is this true? :confused: Or do I have to port and polish the stock heads as well to see any gains? I am looking for the most cost efficient way to go about this?

Porting the intake alone will give you absolutely nothing. Gotta do the heads as well.

Thanks for the info. About how much does that cost? Ball Park figure? The entire job of porting the heads and intake? Thanks again

Depends on who you have do it. The guys at Total Engine Airflow here in Bowling Green tend have a very competative price. I'm afraid I can't say exactly how much it will cost because I didn't actually pay full price for mine. I have been very happy with the results, and the owner is a really good guy.

Visit http://www.totalengineairflow.com and see what you can find. They claim to sell an 11 second Heads / Cam package for $1749.00 I'm pretty sure that's a CC306 cam and doing the work to your existing heads.

Give them a call, ask for Brian Tooley, he's the owner. Also be sure and tell him that you heard about him from Nathan Plemons on https://www.corvetteforum.com Certainly won't hurt anything for you, and it'll help me.
