I love seeing the early d580 LS1 coil packs on the 8.1. It was born to be a performance motor.

582 Richard, not 482. I had to go back and rewind this to make sure I wasn't seeing/hearing something funky, lol. AWESOME to see that cam not giving up a bunch of torque down low!

Good to see the 8.1 getting some love .
These things just never got the attention they deserved . Can't wait to see what a decent manifold can do .

Been sitting on an 8.1 build for a H2 Hummer for over a year now..this video has definitely got excited to finish tearing down the block!

I have a 2008 winnebago voyage motor home. BTW 2008 IS THE LAST YEAR GM PRODUCED THESE 8.1L FOR RV'S, Anyway it has the 8.1L and the Allison MH2100 great combo!!

In Part 2, intake modifications, please describe/show modification made to the interior of manifold. The areas removed along with any porting.

Well, I have a new ZZ502 cam. Now just need a 8.1 and they aren't as cheap a 5.3!
Plus, we need more aftermarket parts!

Correction needed at 13:23 - you wrote and said 482.5 ft/lbs for the gen 6 cam, graph showed 582 ft/lbs.

azlandpilotcar

thanks for the step by step instructions and thorough explanations of the entire swap

Displacement = happiness, prove me wrong

Big Block fun with Richard!! It looks like that intake weights 50lbs! I thought aluminum was lite lol. Great video as always!! Thanks Richard!!

burnz

I would really like to see you run a few of the cams Raylar offers, as a comparison.

brandonallison

I want a cam in my 8.1! I want that torque! Surprised how well that cam liked the engine, almost like it was the cam they should have had from the start
