Proper air cleaner base for aftermarket Holley

[Justin S.]

I'm seeing bases with disclaimers in ads that they will not work with aftermarket Holley's due to the rear accelerator pump.

What will work for a 6210?

Good to know. Your profile shows you have a '70 LS5. Did this base fit over a spread bore Holley and provide hood clearance on a 454 with stock intake?

Mark,
I'm using a torker 2 intake which is approximately 1 3/4" taller than the stock intake.

And the Holley is about 1/2" taller than a Q-Jet. So you're using a taller hood?

Mark,
My build is incomplete but yes I'm planning to use a taller hood.

I also need an adapter for the square bore intake which will raise the carb by another 1/2"

I'm not an expert, but know adapters cost power and space. You might be better off using a spreadbore intake or a square flange carburetor with the torker.
