I'm getting my 408 stroker built right now and I'm goin with a set of L92's for the build. I already have a FAST 92/92 setup but I will be selling the FAST for a LS3 intake and I was wondering would the 92mm TB work on the LS3 intake?

 

the ls3 intake has a 4 bolt design for the tb. the ls1 style has a 3 bolt design. so no you tb wont work if it is a standard ls1 style tb with a 3 bolt design.

 

YES, the 92mm TB will work on the stock LS3 intake. I think you can get away with up to a 96mm TB since the opening on the intake is 96mm if i remember correctly. I measured mine once upon a time.

 

The 92mm TB will 100% work with the stock LS3 intake. Ive done it many times.....

 

^^^^^ yep...
