I am looking to see if the holley high ram will fit under a 6in cowl hood or maybe a 4 in cowl hood in my 68 camaro with the engine setting about 3/4 from the frame to oil pan.i want to make sure it fits before I do anything.Intake facing forward like normal. Any info and pics would be great.thanks in advance.

Mine does not fit. I got a two inch cowl hood with a stock subframe. A 4 inch
Might work tho. It hits right above the "Holley efi" logo.

On a side note pin on fiberglass ones seem to be made with the cowl swooping farther forward than the steel ones.

Mine fit's with a 4" cowl. My hood is a bolt on, but open in the middle unlike the steel hoods available from most vendors. I have a Moroso steel conversion pan that sits about 1/4" from the crossmember though. I have about 1/2" clearance with the hood closed. I don't have any good pics looking straight across the fenders to show how high it sits and the engine is out of the car right now for other work being done.

I am doing a Pro Charged LS3 with a Hi Ram in a 69 and I am very interested in which hood you all found to fit the best

The underside bracing of a 2" steel cowl hood can be trimmed to clearance the intake. I notched out the bracing for my chevelle's hood to fit.

I don't remember the brand name of the hood. I bought it 21 years ago when I built the car. It was listed as a 3 1/2" hood back then though. I put a photo with the hood open when it was still a BBC so you can see how it is open underneath.

Just for reference if your not set on the Holley high ram the Edelbrock clears a stock hood with minor trimming

I should of went with the edlebrock. Btw what's your intake pipe connected to on the l/h side of the car?

????? don't know what you mean?

It's bolted to your frame, Intercooler maybe. Hard to tell in the pic.

ah ya that's the intercooler. just a elcheapo CX racing water to air

could just go with the Holley Midrise, slight loss in power, same design concept. Just my 2 cents. I would be curious if a notched (bottom bracing cut out) 2" cowl would fit it.

here's the measurements
Holley highram:

You serious? They are fucken garbage. NOTHING like the highrise manifolds except the same top. They make less power than a factory intake

I have no bracing cus it's a "lightweight" fiberglass hood and it barely hits I need about 1/2" to 3/4" more room. BTW I did read the midram was pretty bad.

I would go with the Edelbrock over the mid-ram any day. I hate the dual 4 hole lower design that looks like a standard dual 4 barrel intake with an adapter you have to bolt on and then the top plenum. Not sure why Holley couldn't have just made a shorter version of the hi-ram lower intake other than cost savings to use a lower that was already available.

Shows the mid rise (on this particular setup) puts out 31 extra horsepower over the stock LS1. I meant the midsize has the same look as the high rise. Not the same performance. I wish the high rise was 2 inches shorter so it would fit under the majority of the hoods it doesn't

I have a Art Morrison subframe with half height subframe bushings and need a 4" cowl. Fiberglass is nice since there is no bracing but you could cut the bracing on the 4" steel to make it work.

Apples to Oranges comparison. A 6.0 with a big cam and high rev-limiter is going to move a lot more CFM than a mild-cam turbo 4.8/5.3 that doesn't move nearly as much CFM and has a lower rev limiter. You're likely to lose power from idle to the limiter with a Mid-rise.
