Vette(s): 1981 Blue Ice Met. w/pearl ghost flames TKO500 5speed. LS1 Swap 3.45 Dana 44.

I've been running a Edelbrock Vortec Performer 2116 intake since '01. It is for Q-jet/Holley spreadbore carbs.

I had to use a drop base air cleaner housing. I trimmed the lip of the base a 1/4". (The lip that sets on the gasket surface of the carb) And I had to file down the wing nut to get it to just clear the stock '81 hood. Which I think have less of a rise than the '73-'77 hoods.
 
I now have a L-88 style hood on the car which provides plenty of room. Even to acommodate a Nitrous plate under there too.


GEN III 5.7L "LS6" Engine swap
TKO500 5 spd.

3.54 Dana 44
'69 "N11" Sidepipes
Borgeson Steering Box
Born 8/1981
Sequence #3975

Put together 350HO GMPP with Vortec heads so here is whats on the top side. Installed EB RPM manifold with a BG Speed Demon carb. Had to install a 3/4" carb spacer to have enough room to install a vac fitting in the manifold. Running a Proform drop base air filter. The filter is a 2-1/2" tall K&N. Using a SS bolt in place of a wing nut to hold the lid on the filter housing. Have about 3/8" clearance with the hood. suncountry2008-05-21 21:05:24
