Lift Brackets

Searched and searched but couldn’t find the answers to my questions...

I’m going to install the lift brackets on my ‘68 Camaro BB L35 engine and have a few questions:

1. Are the bolts longer on the intake manifold to compensate for the added thickness of the lift bracket? If so, what is the length? Also, are they shouldered/non-shouldered and does anyone sell them (AMK?).

2. What type of bolt is used to attach the rear lift bracket to the cylinder head? Size?, shouldered/non-shouldered?, bolt+lockwasher or just a bolt?

Thanks,

Bob

Some additional info...

I haven’t found any repro suppliers that sell an intake manifold bolt kit that includes longer shoulder or non-shoulder bolts. They’re all the same size. That’s not to say that they’re correct!

No mention in the Chassis Service Manual about different length bolts either. I did find a thread where JohnZ states that the lift bracket was installed at the engine assembly plant:

http://www.camaros.org/forum/index.php?topic=11009.30

So is it possible they were all they same length????BTW...The same question would also apply to the smog bracket that is attached to the right side cylinder head. Would the engine assembly plant install 3 different length bolts (2 for the lift bracket and 1 for the smog bracket)? Guess it’s possible but I haven’t found any proof of that yet.

Does anyone have an L35 (or L34) engine with the lift brackets installed that may have gone down this path?

Thanks,

Bob

Bob, the front lift bracket bolts are longer, black phosphate grade 5. The rear bolt is also black and grade 5. I have restored and unrestored sets of you need them. Thanks, Rich

I have a rear bracket with the bolt. The bolt has a M on the head and is 7/8 long.

I forgot to mention, no washer, no shoulder. I'm assuming that this is correct. It was attached to a '68 head that I've had for a long time.

I just pulled a couple of these off of 1970 402 motors and they were the same - 7/8 bolt with no shoulder, no washer.
