In searching past threads, I have found that the Edelbrock EPS intake (non-air gap) will fit under the hood of a 62. Does anyone know if the air gap manifold will fit without modifying the engine mounts (lower)?

I can't answer your question, but I can say that I have never heard of anyone attempting to gain hood clearance by modifying engine mounts In attempting to do so you change the engineered specs for driveline alignment. That can led to vibrations and damage.
To gain hood clearance some people do not make the change, some, after research get a different manifold and others use a drop base air breather. Dennis

I put a GM RamJet 350 in a 62 and lowered the front engine mount by cutting about 1/2 inch off the lower rubber mounts.
No driveline problems.
But I did have to modify the hood center reinforcement to clear the top of the FI plenum.

They make "solid" motor mounts for racing, which will lower your engine somewhat, but I have Rochester FI, and have run an Edelbrock air gap (Victor Jr) manifold with a Holley 700CFM carb for a while when that was legal in Vintage (not now). It fit without problem on my 63 Corvette.

According to Edelbrock the 2601 air gap is .27" taller than the 2101 performer. I installed the 2101 with Edelbrock carb on my 1960 with a drop base air cleaner and a 2" filter and I have 1" clearance to my hood. So the air gap should fit with a drop base air cleaner and 2" filter but the 2601 air gap has no provision for an oil fill tube so you cannot use OE '62 valve covers.

Thanks for all the feedback. What are your opinions on using a Holley or Edelbrock carb with the Edelbrock intake?

stvaughn

Had another thought bd hbt. Not sure why you want to use the air gap but if it is to prevent percolation, I blocked off my exhaust crossover under the 2101. No real street time yet (stinking weather ) but several hours running in the shop and no percolation issues have reared there ugly head yet with 93 octane ethanol gas.

Performer EPS with Edelbrock 600 CFM carb will fit. I did have to make my own air cleaner base. It is very close from hitting so I would think that you would have problems with the air gap if it is taller.

Does anyone know if the EPS will fit in a 63 - 67 car??

I have been looking at purchasing this crate engine to put into my 63.

It comes with an "Edelbrock Performer EPS" which Pace specially machined to accept a hidden PCV so it will function with the original corvette script valve covers.

The problem however, is that Edelbrock says the EPS will NOT fit under a stock corvette hood. BTW, the EPS is about .50 inches higher than the base 'Performer' intake.

So my questions are:

Is anyone running an EPS or similar height intake in their Mid Year?

Will a "Drop Base" air cleaner give me the clearance to run with this intake?

Is there a difference between a 1962 and a 1960 hood clearance? I've been wanting to use a 2703 Elelbrock intake and a 600 carb. It has a oil filler tube. Thanks

No just the cut out for the radiator (I think)

I'm working on an 2703 EPS installation on my '64. A drop base air cleaner will need to be used. The air cleaner is a 1 inch drop Pro Form assembly.

The base plate is low enough so that it rests on top of the AFB choke housing. A ball peen hammer was used to dimple the base plate inward slightly for choke housing clearance.

A 3 inch filter element is too tall for stock hood clearance. A 2 inch filter element will work. Underhood clearance between the air cleaner assembly with 2 inch filter and bottom of hood is 7/16 inch. Trans dapt makes an air cleaner element that is 2 1/8 inches.

I'm thinking of modifying the top air cleaner plate to add some additional filter media to enhance air flow.

Another possible fit issue:

That Pace engine is built with a "long" water pump, as opposed to the "short" water pump with which your car was built. That means the pulley flange is 1-3/8" further forward from the block than stock. With fan and fan clutch, is that going to fit behind your radiator?

The tall intake manifold and the long-style water pump, to me, don't seem to be wise choices for what's supposed to be a drop-in new engine with the old-school Corvette look. It might be great if you want to put a "Corvette motor" in your Impala, but it seems like there are at least two potential fit issues if you want to put it into a Corvette. i do understand that there are some workarounds for the manifold height.

I am trying to figure out how to convert my quadrajet intake to one with a fill tube and use stock Corvette script valve covers. I see that Pace modified the intake to include a PCV valve. Anyone know how this was done? Pictures?
BTW, I'm running a 350 sbc with a long neck water pump and fan clutch in my '59. No problems.

Jofa1963

thank you gentlemen, I hadnt noticed the water-pump issue either.

Since there is conflict with the intake and water-pump, I'm thinking that I will just buy a GM crate engine that comes without intake etc, and modify an intake on my own (I have a spare Edelbrock Performer intake I can experiment on)

I searched around a little and found a previous thread on modifying new intakes for using the Corvette script covers on new motors:

Here's a pic of an intake they modified:
