UP CLOSE: Ernie Irvan's 1991 Daytona 500 Winning Intake Manifold & Cylinder Heads (Larry McClure)

What happens here

The speaker emphasizes the top-secret nature of engine building during this time. Key figures like Runt Pittman (head engine builder) and Mark Giles (welder) are mentioned for their roles in these complex modifications. Machine shop work was done by Mike Hipps, and intake specialists like J.A. Beard handled specific areas. It was common practice for teams to test various configurations on a dynamometer, even using temporary pieces, and only permanently welding in the final best-performing piece to optimize power.

Goal: Appreciate the specialized roles and secretive processes within NASCAR engine development

What they say

Hide

up go run what does this right here do uh nothing so you know what I mean yeah you just didn't want to get out so it uh but you know Larry might know this is so cool but yeah as you can see all the welds see where it's all been it's been cut up and put back together well you would what you would do is that would be cut right here you'd take this chunk out and you'd have two or three of them laying here and you put it back in there put a gasket on run it on a Dyno it didn't work you took this one back out your final piece you weld it in oh yeah this is the best piece let's weld it in that's right because you there was like a rule that your height could be whatever you want but it had to you couldn't have a spacer over a certain height because that's what Screwed Mark Martin in 1990. so if you weld all this together it was legal is that how that works right okay see yeah Mark Martin's intake was not welded
