how much hp will i gain for getting a lt4 intake manifold instead of my stock lt1 one, or what about getting it ported from AI how much will i gain?
thanks

 

what mods do you have?

 

stock, next year i will have too many mods like AI heads fully ported (550 naturaly aspired), ram air intake, 58 tb, big fuel injectors, z06 maf, borla or loudmouth exhaust, long tube headers, hi flow cats, 1.6 rockers(or 1.7),comp tune up, bosch platinum 4 sparkplugs, good spark plug wires too, royal purple oil, and some others...

 

You can't just bolt your LT1 heads onto the LT4 manifold. You must run Lt4 heads with the LT4 manifold.

 

there would prolly be some gain from the lt4 mani but it would have to be port matched to the heads i think. the only difference between it and the stock lt11 is that the intake runners are shorter and the ports are higher up, so it might bolt up but the port alignment is off.

 

The only real difference with the LT4 intake is the raised runners. This is because LT4 heads also have raised runners. I dont believe you can even bolt an LT4 intake on LT1 heads but if you were able to then it would probably hurt performance as the head ports will be slightly smaller than the intake ports... not something you want!

 

LT4 Intake Manifold only works with LT4 Heads, and the gains are minimal at best. Just get your stocker LT1 ported out, I just gasket matched mine with a dremel when i had my heads off.

thanks but the thing i hate the most about mine is i hate the stock grey color, do you know where i can go or any where i can ship mt intake so i can get it powder coated to red? or do they ever sell any already powder coated ones on ebay?
thanks all, i wasnt aware about it

 

Open your phone book look for a powder coating company, have it powder coated. It's that easy.

 

I painted mine when it was off the car. Oreilly's engine paint. like 5$, still holding strong. Looks good too. Just make sure to tape off the top so it still looks shiny silver in the grooves.

 

where can you buy it at? do you have any link? and where can i get those chrome strips on the top of it

 

They're not chrome, you tape that off, so the paint is in teh groves, this being after you polish the top of the intake. giving it that chrome blang blang effect.

 

do you have any link where i can buy them from?
thanks

 

Buy what from? YOU DONT BUY YOU POLISH

 

sorry i misread, lol you didnt have to yell!
