Get spacerized!
 Raise your blower out of the valve covers & set your ride apart for less than a decent carburetor would cost you with this 4" aircraft quality aluminum intake manifold spacer plate.
This is a trick piece! Polished, heat treated and weight relieved.
Bigger is better and now you don't have to buy an expensive gutted boat intercooler to do it.
When you space your supercharger up it makes a huge difference on the "wow" effect!
I tried shorter and I tried taller and wasn't happy with either this spacer sets your blower height just right.
 Acting like a big heat sink you will notice your motor running better than ever!
It fits any vehicle with a 6 thru 12-71 blower set up, will also work on a 14-71 as long as it has the standard 6-71 bolt pattern. Compatible with all brands GMC, Mooneyham, Littlefield, BDS, Weiand etc…  Super easy installation, uses 4" longer mounting studs,  an 8" longer belt, throw a gasket top and bottom and get ready for some attention!
This is a must have for your supercharged car, truck, hot rod or boat. It's perfect for adapting a large bottom opening 1271/1471 to a standard bottom opening manifold and vice versa.
Especially needed on certain engines for distributor clearance. Easily milled to any custom thickness. 
 You will probably  have to pay $400+ in materials and a machine shop well over a grand in labor alone to tool this up for you and that's not polished yet.

Comes with Studs and Gaskets.
