what will it have?

GM847 (or maybe lloyd elliot LE3 cam) with nice behive springs, 1.6 rockers

stock heads with fresh 3 angle valve job

Pacesetter LT headers with true dual exhaust (no X or H just a foot of piping and flowmaster 2 chambers off each header)

CAI, electric water pump, 58mm tb (intake matched),

and an AWESOME dynotune

 

350-360rwhp is about right for this combo. But shoot...if the heads are off for the valve job why not get some porting? Throw a thinner gasket under there for more compression. !AIR and !EGR and then with the head porting depending on flow numbers you can get close to if not at 400rwhp. mmmm damn nice.

 

well the air and egr are already gone... the 3 angle valvejob was done last time i had my heads off... all i would be adding to my setup would be the cam, valvetrain and 58mm tb and i dont need to remove the heads for that (screw buying another $150 head gasket set!!) so i guess a better question would be how much power would i add to my 313hp/340tq that i have now by adding the LE3 cam, 1.6 rockers (agressive valvetrain) and the 58mm tb (with a good tune of course for the cam)

 

The le3 cam is designed to work with a set of le3 heads or le2 heads depending on which setup it was made for. Not every le3 cam is the same just so you know. Also where do you plan on getting the le3 cam because you can't get it from Lloyd without buying a set of heads.

I'd just go with a gm847 for now and it should put you around the 350rwhp range, but remember peak dyno #'s don't mean crap, its the torque curve you want and with the gm847 the curve will be ok but not all that great.

 

well then....try a custom cam instead if you've got the funds. Because you won't be able to spin the motor high enough for the 847 with the stock lower end. A custom cam can be just as aggressive and make better power and tq under the curve. Along the lines of 360rwhp and 380+ rwtq. But if you are strapped for cash then a 209 dollar 847cam is the way to go. Or.....you could go solid roller with some serious valve train and make more power with more driveability if you have extra dough.
