Holley LS Hi-Ram EFI Manifold - Black GM LS1/LS2/LS6

LS1/LS2/LS6 Cathedral Port EFI for 1 x 92MM Throttle Body

Overview
The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more! The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits. Cast aluminum construction. Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

*** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions.

My son (17) ordered this suit to wear to Prom (2 weeks before) and it was a hit! Great Quality and great fit! He even convinced a few of his friends to buy their suits here too! Would purchase again for sure!

This is a terrific purchase.
Size: Large, Color: Navy Blue, Size: Large, Color: Navy Blue
Amazing for the price. It’s a wonderful suit fit just right for a 5’10”. 145 pound male. The quality is surprisingly wonderful for this suit and the color is accurate. As in the picture it is a slim fit and accentuates his figure. I would highly recommend this for a purchase. (be sure to use the measurements on their description before ordering). After a steam and a press we were ready to go. The packaging was very nicely done also.

Perfect fit.
Size: Large, Color: Dark Gray
I’m 5’9”, about 180 lbs. I got an L based on the Amazon recommendation. The size chart showed the pants being a 36” which is big for me but it’s those that stretch so if you’re a 34” like me, it’ll fit perfectly. No alterations needed for me. Great fit, good looking suit, nice material. I immediately bought another and hope it fits as good as this one. Genuinely impressed.
