Holley Hi Ram or Mid Ram?

[7firebird1]

Hello all! I have a 1971 Firebird that is getting an LS swap and wondering if the Holley Hi-Ram EFI intake would work with the stock ram air hood or should I use the mid-rise?

NO way the HI-ram will fit under a stock hood...

That sucks! Lol. Didn't figure they would but wasn't sure. Thanks Andrew.

Just want to share this intake comparo for what it's worth.

The Holley hi ram made the most power, but only barely more than the FAST 102. The 102 made more torque.

The FAST 92 is an easier bolt on but makes less than the 102, but it still made more HP and TQ than the Holley mid rise.

I was kinda surprised by some of the results of that comparison.

What LS engine were the comparisons done on?

The mid and high rise are better with more aggressive cams.

Yea no way the Hi-Ram is gonna fit. Wasn't even close on my car when I did a check. I think the Mid-Ram will even be close!

This is looking across the top of the fender.

Wow!! That sticks up quite a bit!! Thanks for showing me that!! May have to go with the Fast intake. That sucks because I love the look of the Holley!

If you decide to go fast and have ls3 I have one with rails. Went with a RCI billet intake on mine as I'm boosting.

If you can find someone with a mid ram give it a shot and see. Like the look they're just talk for old cars.

I installed a mid rise last weekend on my LS3/525 in my 69 Camaro with SS hood. It has plenty of clearance. I have a Speedtech sub frame that may set the engine lower the a stock sub.

That looks sick!! Love the look of those Holley intakes. I would consider the Fast intake you have but mine is a 5.3.
