Painting that intake is more like Blasphemy, but I like the direction you're headed with it!

 

There is no shame in painting that intake

 

yeah, it's kind of rough...but it looks right disguised as cast iron! thanks again

 

Not to guy's like us there isn't. Although, some would give their left testicle for it the way it was. That's the difference between us and purist's.

 

It comes off as easy as it goes on.

 

That intake is oddly pitted, the purists wouldn’t want it. Painting is probably the best option to make it look right

 

Total SBC newbie here, owned one for a full week now!
Wasn't there a fairly large aluminum heat shield on some of them under the carb?

 

They were stamped steel, riveted on

 

Wasn't that a kit that was avaliable through GM Performance?

 

Lots of 300 hp 350s had em . But with quadrajets.

 

yeah, I have one of those. They work with Holley carbs, not AFBs

There were 3 different heat shields used on Chevy intakes. The steel one that was "riveted" to the bottom of the intake. The stainless steel one that fit under the carb, to contain the open exhaust crossover that heated the carb base. And the aluminum one under Holley carbs on some of the hi performance engines.

 

in my dream plans, but not my current reality plans.

 

Squirrel, you might want to double check the calendar. I'm registered for Sick 66 as well, but in October

 

yeah, it's in October....typo, my mind must have been thinking of the other thing in August with the off topic car.

 

Yep, just thinking it might help camouflage the runners I quoted.

 

yeah, it would!

 

That heat shield looks good there. If you don’t want to modify the factory shield, you could cut one out of plate and stencil it yourself. Of course it does appear to be 3 different size fonts. Still very doable.

 

If I make a heat shield, it will be shaped to keep heat from the side mounted float bowls on the AFB, not the front/rear of the Holley

 

Been messing with Chevy V8’s since I was 15 and I’m 75 now. Never saw a factory original engine with a heat shield on it so I googled that. BBC engines with Quadrajets on iron manifolds and an open exhaust heat crossover under the base of the carb had them, as did cars with RPO NA9
(Evaporative emissions). Maybe those were on both Q-jet and Holley carbs, I don’t know.
Sorry for the thread hi-jack, but I learned something today.

 

The 350hp 396 with the Holley on an iron intake also had the open heat under the carb, and used a stainless shim heat shield under the carb.

The small blocks in the mid-late 60s used it under the Qjet as well as the big blocks.

 

I had a ‘69 350hp 350 that had the heat shield under the carb, i was the same size/shape as the gasket.

 

Now that you mention it I have one of those stainless shims in my hoard.

 

Jim, you had some issues with heat soak, IIRC. Make your own shield, and if you aren't running out of height, you could sneak a phenolic (sp?) spacer under it too.
Looks stock, hides mods, adds performance!

 

That's the plan...although the phenolic spacer I bought for the previous setup won't work with the new one. I do have one of those layered plate/gasket spacers I'm planning to try.

I also blocked the heat crossover passages by using the blocked intake gaskets.

 

You will run out of height real fast on a C1...ask me how I know.

 

yeah, I'm aware of that.
