dyno day-330 crate motor with 142 blower

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.

Thats not bad. When my 350/330ho was stock it dynoed at 289rwp, cant remember torque. But it was thru a muncie 4speed and 12 bolt rear. what size air cleaner were you able to run under the stock hood?

I have a b&m 144 on my 69. 2In goodmark hood, 3in dropbase with open element top. Had to trim on the understructure of the hood. Works fine though.

I have 2" cowl hood. Looking to install my new polished 142... I have 2" drop spacer for carb. Will a 4" or a 2" element fit with the k&n assembly ? I hope it fits period ..

You may need to trim the air horn off of the carb to get air flow with that small of air cleaner. A couple people on this board have the small blowers installed.

So a 3" carb drop spacer and 2" air filter and my 142 may fit under 2" cowl on my 69??

Re: dyno day-330 crate motor with 142 blower

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.
