Swaping in ls2 engine, trans and computer from a trailblazer ss in my 95 camaro z28 mods wil be a cam not sure which yet longtubes headers, ls6 intake, 3in catback and dyno tuning rear has 3.73 gears. What type of profomance should I expect from that setup? And is there a big difference in proformance between the 4l65e and 4l70e?

 

hah...that's about as vague as you can get.

not much different than saying...."i'm gonna put a new motor in my car, not sure what size or kind, other than a V8...what kind of power can i expect?"


figure the stock ls2 will put down 320-340rwhp

a cam could bump that up to 450rwhp or anywhere in between.

hows that for an aprox answer?

 

A pretty decent one. The cam is going to determine a lot. Even the catback may make a difference. I am probably losing with the Flowmaster on mine, but I tried a magnaflow and have heard a few others, and the B&B is the only one I like better than Flowmaster but not in my budget right now.... Back to your question. Got to fill some details in, and a tune can be worth 30-40 or more.....

 

ttt

 

what part of more details did you not understand??

 

Anywhere from 380rwhp - 440rwhp depending on what cam, what tuning, converter locked/unlocked, etc.

 

Is an LS6 intake useful on an LS2?

 

Believe it or not, the LS6 actually outflows the LS2 intake by a small margin.
