Aluminum intake BB bolts?
« on: July 13, 2017, 04:40:24 PM »
Hi,
I bought a master screw kit for my ZL-1 project but I don't really understand where all the stud bolts should go when mounting the aluminum intake?
They look like this: https://www.camarocentral.com/1969_1970_Intake_Stud_Big_Block_p/enc-338.htm

As I t says there one should be for the alternator bracket and one maybe for the fuel block, but the rest? It's four of them in the kit.

Right here.

Probably intended to mount an idle solenoid bracket that was not used. 'Location C' is defined as the 3rd, 4th & 5th intake mounting points.

Great William, but why do they don't have extra bolts in the kit for all of us that don't need the studs?
There only three washers and not four either, strange?
Where did you get that pic?

Near as I can tell all ZL1 engines were assembled with the studs, used or not. They are visible in original engine photos of ZL1 #3, a 4-speed.

The drawing is a page from the ZL1 engine assembly manual.

It was reproduced [19 pages] in a 1994 COPO Connection book. The copies are blotchy and difficult to decipher. Makes for interesting reading. I once thought only hacks used Teflon tape; plenty of it in a production ZL1 engine.

Ok, thanks William.
But you don't happen to have that book, do you? You can send me an PM if you have....

I don't seem to find any engine pics of that #3 ZL-1 car, did you have any of those too? ;)
