Hello, i just bought an 81 and am builing a motor for it, i'm planning on using bow-tie vortec small port heads and am looking for intakes, i think i have settled on gm vortec low rise with egr part#12496820 i was wondering if anyone has used this intake and if it will fit under the stock hood of the 81? i will be running a q-jet on this motor, i think it will fit with a drop base air cleaner but can't find any info to verify this. Thanks

I run a performer vortec intake with a Qjet, and my stock aircleaner. It all fits with about 1/2" clearance on a stock '77 hood. You can go to the edelbrock site to get the intake height and compare it to the one you listed to see if the height is similar. A drop base will definitly create more room.

I am using the 12496820 with the q-jet and drop base air cleaner. But you will need to find a 2x14 filter element. The drop base usually comes with a 3 inch and on mine the wing nut would touch the hood when closed. 2 inch will give you 5/8 th clearence with an 81 hood. I have yet to put my 77 hood back on and that will free up some more room. Had to make the window on the distributor cover a little longer so the air cleaner base would fit. Filter by STP SA 3648 Overall hieght 2.5,filter suface height 2.0.

sweet thanks guys, are you running the the think carb gasket or just a paper one, i was think of running a basic paper gasket to get that extra 1/4" clearance

I use the 1/4 inch gasket, It provides some insulation.

shortest vortec intake is professional products p/n 52007 ... it IS for Q-jet ... but is does NOT have egr.

vortec PP 52007 A = 3.60", B = 4.90", AVG = 4.25"
