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.

Not as Bad as I have heard
Format: Paperback
Decided to order this book I had heard so many bad things about it. But to my surprise it was pretty darn good.. I have two complaints. 1. The art in issue #6 was up to par. 2.. It ended to soon. Would like to have seen it continue at least up to issues 24 or 25 giving a new creative team a chance to see where they could take these characters.

I’m Hooked
Format: Kindle
Great storyline. Kept me hooked from the very beginning. There’s a Dr. Who vibe that comes to the fore later, and it’s fantastic. No, sorry… it’s Terrific.
