I recently did a engine swap in my 99 trans am from ls1 to an ls6 right now i have long tubes to true duals, 373 and a tune... i want to do heads and cam but im not sure what is a good combo and what other supporting mods i should do such as injectors etc. i want to go with a pretty aggressive cam. please help thanks

 

sticky! theres tons of good info in there

 

i tried to open that sticky but cant

 

How much are you looking to spend? What transmission do you have?

 

i want to spend around 3-4 and its stock now but im going to either rebuild the internals or get a beefier one

 

6 speed?

 

yeah its a 6 speed...

 

A cam swap often is around 800-1k, you should upgrade to at least a LS6 intake which is 300-350 and ported heads can be had for little over 1k and then add the dyno tune, it can be done but it's TIGHT.

As for combos, go to the dyno section and start combing through.

Also think about what the intended use of the car.

Furthermore with the m6, you need to consider the rear if at the track, it has a whole different kettle of fish to race that car and even if it has Drag radials and suspension, its either will light up the tires or bog and possibly break the rear.

I guess you need to decide what the intended use.

 

Cam, I would get something in the 228 or 232 range 590's lift range on a 112 lsa.
Heads, check out AFR, trick flows, PRC's.
As said above a ls6 intake, dyno tune, hardened push rods, new oil pump, timing chain, and lifters. That will be most of your 3-4k budget.
