i am currently putting together a 5.3 liter ls engine im my 86 camaro and would like to know anyones personal oppinion for a camshaft for my setup. i will be running the stock shortblock with some type of camshaft and an aluminum intake, tci super street fighter stall and ab 7-10 pounds of boost. i was looking at the lingenfelter GT2-3 camshaft but im not sure this is what i need. Any info would be greatly appreciated!!

 

GT2-3 is a favorite of the turbo / nitrous guys for 346 displacement. The motor I bought for my ls1 swap had it installed already. Its all here-say, but he said the motor absolutely screamed on spray with that cam. not sure what that equates to for turbo and 5.3 though

 

the cam will act like it has 6* more duration ing a 5.3L application.

ex. TR224 cam in a 5.3 would act like it was a 230/230

Your best bet would to be look for somethin a little smaller

 

So what would be my best choice? i know the duration should be around or under 220. but im not the best camshaft person.

 

i think im going to just call xXx and get john to make me a camshaft....

 

Not sure what your looking at if your going boosted, your looking 214-216 area for duration, and you want min 116LSA so you can build boost if your planning on turbo'ing the car

 

i think i would come out better just emailing comp. and Flowtec Induction and ask them what they think....

 

You don't HAVE to have 116LSA or higher to build boost. There was a guy on ls1tech a couple years ago that ran a custom grind cam with a 112LSA to test out his theory on cleaning the combustion with the extra air from the valve overlap.

I think it worked pretty well. He put down around 500-550whp with a cam, bolt on and p1sc procharged ls1 at around 5lbs I believe.

I don't see the problem running the GT2-3 in a 5.3 really. It might move your powerband up some but its not going to make the car hard to drive by any means.

 

I have a LPE GT2-3 cam sitting on the shelf, I'm not going to use. PM'd me interested in it.
