Today's Project:

[Z Code 400]

I am helping Dad install a 502 BBC crate motor in a 1970 Firebird today. I pulled the 455, changed out the bellhousing and have the engine ready to go back in. The car had the Heddman #28150 Headers on it and I am curious if anyone can comment on how the Heddman headers for the BBC will fit.

The customer included Hooker Super Comps and I already see (3) places that look like they will interfere with the chassis.

Installation is on hold pending feedback. Thank you all very much for your input...Robert

[JC455]

Can't say, but.... seeing as that you have that boat anchor Pontiac taking up space, I'd be happy to remove it for you-- NO CHARGE!!!

JC,

I need to open it up and see what let go. Sounded like a rod and I am hoping to save the block if possible...Robert

Sounds like a stupid customer. The heddman headers fit tight in a camaro, might even need bfh in a couple spots. Make sure to change the front body clip to a camero too, because that's all the firebird will be with the bbc in it. Another worthless ugly camero.

Z code what did you do about headders?

[Z Code 400]

Rtanner,

We ended up using a Hedman header for the BBC in a Camaro. Fit was good. No hammer required...:-)
