With 62403's w/Springs+ret. and a 8k redline... Im thinkin the stock ls is gonna hold back!!!

What will fit the manifold that is better?

 

you can use the stock T/B if you want or send it to a good machine shop and have them bore it out.

 

i thought eriks(sp?) racing had a nice tb out for around $350-$400

 

i'm sure they do but for about half that price you can have your stock T/B bored out and it will do the exact same thing.........

 

i can't figure out whats wrong with my skunk2 manifold install.. installed it and now my idle keeps moving up and down... maybe i need a bigger throttle body?

 

are you sure you connected that one little hose? my idle went up and down when this little hose came off..

 

check for leaks...and also check your idle screw.

 

I have the same problem ... but mine is from a warped Intake Manifold .... water came through the intake manifold into the #1 cylinder ... rebuilt the engine ... but the #1 intake runner is slightly warped so it doesnt but up perfect against the OEM intake manifold gasket ...

to test yours for the same type of leak ... get a little WD40 ... have a friend rev the engine ... and spray it near the gasket ... if there is a leak .. it will suck the WD40 right in .. shut the car off ... and either double up the gasket ... or get a new intake manifold (:


could be the Throttle screw too ... adjust it and see if it makes a differece... ummm lets see as for the Throttle body ... LS throttle body is 58mm you can get a brand new Holley 62mm or 68mm throttle body for like $360 3 diff colors ... and sell your old one on EBay ... check the intake manifold specs to see how big a TB it can take without getting it machined

 

what little hose?
