Here's one example of how some of us achieve it.



In this case, I had the base machined so that the air horn that protrudes up from the carb is removed. This alone creates about 1" of clearance. Then you have to make provisions to clear most dual bowled carbs. Easy...drill two 1" holes and use valve cover PCV grommets to isolate the base plate and keep it from vibrating.

Now to get even MORE of a drop, you would need to have the billet base wrap over the carb. This would get you another 1/2" or so before you start making contact with the throttle arm.

I always figured with the above modification, along with an additional 1/2", one could get a 2-3" air cleaner to fit under any Cobra hood. This is the end result:

Hello Dean, I did the same to my base, then we straped the car on the chassis dyno and the results were very poor, when it came to the cfm flow and the motor was also,.... lean. So, I had the intake carb flange planed off apx. 1/4" and I now have good hood clearance with no effect on the cfm.

With a 14" round (or so) air cleaner with a drop base, I doubt it would hamper cfm at all because 3/4" of the filter is above the carb. With our short height 1-3/4" oval air cleaner, you really reduce the air intake to the carb.

Be careful.

Blas- that's a nice tow hook idea you have. Is it removable ?

I put mine in the drivers side brake vent and bolted to the frame horn but, I'm concerned that the tow rope will screw up the paint ?

Did you try going under, the car ?

Also, take some more damn pics of your SPF ! (just 1) lol !!!

Not wanting to steal this thread...so I'll start another one regarding the tow hook in the SPF area...

Thanks.
