I just ordered a Holley alum heat shield and it comes with a 3/8 insulating spacer.I just wanted to know if I will experience any loss or gain with this little spacer.I can already see that I need to open up the spacer hole and the hole in the heatshield to match my intake.I almost forgot, the divider in my intake is already cut down a half inch on the Weiand Stealth. This is going on my 466 560 horse.I was having a vapor lock problem because of the tight confines of the engine bay in my 68 stang.
Thanks Guys
Bob

The 351C in my Sprint was having a real bad vapor lock problem, and I bought one of those heat shields. It cured the problem 100% I'd say you'd pick up a little throttle response, but at 3/8" probably not enough to notice. ------------------

I know it's not what you asked.But a scoop will help alot with getting cool air in and around the carb.Even a small scoop can make a big difference.SCOOP ------------------

On mine it got so hot you couldn't touch the carb, and you could hear and feel the fuel boiling inside the bowls. I was also battling a cooling problem at the time. ------------------

Have you checked your fuel lines, to make sure they are not to close to any heat.

Hey Steve I could also hear the fuel perculating in the carb.
Fastymz I did check all of that also.i was careful to route all of my lines away from heat.Its just that everything is so tight in there with the big block.but she sure does run!!

Thanks for the heads up Rich I didnt like the looks of that kind of heatshield. anyway Jegs sells them.I got mine in the mail already.I looks like I may have to move some things around on the intake to clear the shield maybe even trim it.
