Holley 600
Wieand action plus
Moroso drop base 3" open
Fit with 3/4" to spare

Future:
Plan forward is a Magnuson mp122" blower hopefully under the L88 hood, if not I'll cut a hole in the stock hood.

Hope this helps.

The Holley is a low rise single plane intake.


I also bought a Weiand 8123. It is shorter by .02 then the Performer 2.0 and if it's close I'll mill the carb pad for more room.

That intake is a hp killer-especially if not directly connected to the outside.

Spectre has options to connect up but I decided to go less expensive (Cheap) at this point and just added the cone filters on the 4" intakes. Being 4", there are plenty of options.

resdoggie

I was told the X-treme air cleaner tops kill HP also. If that were true, had to do with how the air was flowing into the top of the carb as opposed to coming in from the side, can someone explain how/why? Just curious.

new 4 bolt 355 I rebuilt from a 76 c10 truck core with an "assault 1500-6500 polished intake" (rpm style clone)

greenwood twin turbo hood (lower rise one)

about 2" of clearance with a 3" spectra air cleaner with1 1/2"drop an an edelbrock carb with a 1" wood spacer....

Just checked with the modeling clay:
1. 1975
2. SB "355"
3. L-48 Hood
4. Holley Street Avenger, electric choke, vacuum secondaries
5. Edelbrock Torker 2
6. Round 3" x 14" air cleaner. Base has one and a quarter inches drop.
7. Fits easily, tightest clearance is one and three-eighths inches.

Interestingly, the tightest clearance was where the rear of the air cleaner lies under the hood (red circle in picture). This could easily be remedied by filing/removing a bit of the inner panel.


Thanks for starting this thread, I had been meaning to check the clearances for a while as I am wanting to switch intakes.

right now now air cleaner set up, the one I had for the stock intake doesn't work with the performer intake…

Any ideas on what set up I can use?

1. 1969
2. SBC
3. Stock 1969 small block hood
4. Holley 4150 DP
5. Bow Tie LT1 style high rise
6. Stock drop base open element. 14"X3" element
7. Works fine. As I recall, about 3/4" clearance at closest point. Basically an LT1 setup w/o a carb insulator under a stock SBC hood.

The LT1 style base should solve your problem, or at least get you close:

labhound

That looks like a big drop base, I might try that……..whenever I get my hood to open again….

Sklaris

Option for checking hood clearance if you don't have putty is lightly crumbled aluminum foil. Works great.
