Default Holley Hi Ram or Mid Ram?
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...

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.
