Opinions on turbo mfgs
Thanks Jose, we are trying to stay away from the GT42 especially in the tight confines of the LT1 engine bay
You know how it is to put anything in there
650rwhp is the target.

People don't like to read is my conclusion. The information is out there, its just simply ignored. A 408 will work just fine with a SXX series unit all day long. Also twins work great, but packaging with them is another pain as well. But twins are nice indeed as well.

Packing twin T4 60's or 66's would be easier than hanging a T6 big turbo in front of the engine think. The big T6 stuff is the size of a turkey roasting pan.
Some of the turbos like the GT42 and S series units are not to big. Its the big boys like the TV series and GT47 and GT55 which get really big. Twin T60's will work with most setups indeed.

If that is the case, then the 76GTS will be the unit to have. You won't find a unit that small and make more power then it.

Just don't wanna go too big if I realize 500-600 is good enough
....but who knows, I got plenty of time to think about it 
I still don't understand why folks on this board think 76mm units are big. Heck we run 76's and larger on Supra's with half the cubes...lol. With a 346 CI engine, their is no such thing......you still are making big power off boost...hehe

Street kit and fast response, I would go with a GT42 unit up to 800-900rwhp max. If you want more then go with an S74 or S76.
