I'm installing a fresh 347 into my 88 GT. Can I put my Mac shorty headers on the motor and then install it? Or do I have to install the motor and then the headers?
Thanks a lot. She'll be going in either way tomorrow.
I've never done it with the headers on, but I would think it would be more of a pain than it's worth. The shorty headers are really easy to install once the motor is in, so I would say install the motor then install the headers. Otherwise I think your just going to make more work for yourself.
i installed with the BBK shorty headers with no problems, maybe an extra 15min of fiddling to get her in but it's worth it IMO. The only thing i recommend is dropping the H pipe, the last time i installed the motor with the H pipe in position and the headers on..what a PITA the exhaust flange studs kept getting caught in the H pipe
If you are planning on installing them with the headers on, I would suggest putting some cloth around the primaries to keep from scratching the headers and the things it comes in contact with.
It should work fine. Either way there will be a bit of wrestling. Trying to get the engine in or trying to get the driver side rear bolt in the header.
