That depends upon the heads you are using. Do they have 2V, 4V or
aftermarket (AFD, CHI 3V, Ford Motorsport or Brodix high ports, etc.).

I would have said the same until I dyno'd a mild 408 cube 351C-4V
stroker recently. We tested a ported Ford aluminum dual plane (similar
to Boss 351 intake but with Holley carb pattern), Edelbrock Torker,
Blue Thunder and a Holley Strip Dominator. The Blue Thunder performed
worst and was down 40+ HP to the Strip Dominator. I can attached a
post with the details if anyone is interested. The ported Ford intake
did surprisigly well. Engine was just shy of 500 HP on the best pulls.

> Even Edelbrock has a relatively new Air-Gap available for the 4V Cleveland.

The Edelbrock Air Gap intake is for 2V ports though it will bolt up
to a 4V head.

Here are some intake heights that might come in handy:

Edelbrock F-351 & Performer 2V/4V 3 1/2 4 3/8
Weiand Xcelerator 2V 4 3/16 5 1/8
Holley Strip Dominator 4 5/16 5 3/8
Blue Thunder 4 7/16 5 3/8
Ford aluminum 4V 3 1/4 4 3/8
Offenhauser 360 4V 3 1/2 4 1/2
Weiand tunnel Ram 9 1/16 9 3/8
base only 6 1/4 6 1/4
top only 2 3/4 3 1/8
Motorsport A351 (Roush) 6 3/4 6 3/4
A331 (Edelbrock version, not Roush) 4 3/8 5 5/16
