Local speed shop had a dyno day - 2 pulls with AF for $40. I was impressed with the power a little 142 Weiand blower (low profile one) added with about 5-6 lbs of boost. The think the original specs on the GM Performance motor were 330 hp/350 tq at the flywheel and the only thing I did was swap out the vortex heads for higher cc World Sportsman heads to lower the compresson. On the dyno, my numbers at the rear wheels were 341/400, so Im figuring around 410/480 at the flywheel. The blower at real safe boost appeared to have gotten me about a 25% increase in hp and 37% increase in tq. I like the little blowers. They dont seem to heat up like the big ones, they are relatively cheap (I got mine on sale), they are easy to install and can fit under some hoods.

It may fit there are factors like what you have for engine mounts as well as the condition of your body mounts. Others have tried it on this board. I think it was wheezer and wardee if memory serves me correctly.Good luck and let us know how you make out.
