mad dog headers 79 gp 455

[CDUNIGAN]

This is what mad dog has listed on his site. Has anyone installed a set before? As you can see he states that his will fit a 301 with a small starter. I have a 455 with a heavy duty starter. I am trying to get an idea of what Im dealing with.

This is from his site.
Auto trans, small starter, fits with factory 301 block and frame pads
Part #9170 - D-Port Heads, 1 3/4" primaries, 3 1/2" collectors.

This has come up a few times recently.

I'm still eyeballing those too for when the time comes. If not those, I may just go for the RA manifolds.

A cleaned up coned outlet RA manifold is also a very good choice. Personally in a non stock ie non concors type restoration application such as a 455 in a gbody I would have to do the headers. But I would do it right the first time with good gaskets such as remflex and either properly paint them or get them coated.

I BOUGHT A SET OF THESE HEADERS EARLIER THIS YEAR,,,FIT IS O.K. ... RIGHT SIDE HAS FORWARD TUBE DETACHED FOR INSTALLATION...LEFT SIDE HAD TO BE CLEARANCED ON 1 TUBE TO CLEAR EVEN THE SMALL STARTER ( AFTERMARKET GEAR REDUCTION)...

1981lemans455,

You should let the manufacturer know this. He is a very small business and is just down the road from my house. I am sure he wouldn't mind feedback.
