SB 350
L-48/L-81 (stock low rise hood)
Edelbrock 2101 Performer Intake
Edelbrock 1406 Carb
Stock Air Cleaner with Stock Cold Air Intake
It fits but has only 1/4 inch of clearance verified with the playdough method. Had to install a 1/2 inch aluminum spacer/adapter to make stock air cleaner fit the new carb. Also had to move one metal tube on bottom of air cleaner to allow the fuel pump to open fully.

383 SB
Stock hood - L48 (for now)
Q-Jet
Performer RPM
Proform - 1 1/2" drop
About 3/8" of clearance. When I put a different hood on it, I hope to put the stock air cleaner back on.

Stock hood
Edelbrock carb
Performer RPM Air Gap
Edelbrock 1" drop base w/ 3" air filter
Doesn't fit (I knew it wouldn't) Going to be adding hood scoop; probably stinger style. Need about 2 to 3 more inches of clearance.

That is a great looking intake/filter set up. Have you provided any build info in a previous thread, or can you elaborate on how you made it up. Looks like various available parts combined with your customization to put it all together for a great result.

Fits good made My own solid Motor Mounts that lowered Engine by about 3/4 inch to fit the Truck fuel injection manifold, but eventually went to Carb instead.

4. Quick Fuel SS VS 780
5. Edlebrock Performer RPM Air Gap
6. Chevrolet Performance drop base
7. 2.5" K&N but 3" works. With the 3", the lid will rub on the hood insulation, which is fine, but my air cleaner lid has custom graphics so I use the 2.5".
Also have a poly motor mounts...do not know if that changes the engine height or not.

To purchase another hood, and do more paint and body work, this was the best move for me, plus it looks stock.
