Can any one out there comment on the idea of cutting off the 6 inches or so of the heat exchanger where it meets the heads and adding flanges there so that the exhaust can be dropped without disturbing the head joint?
I have a spare set of heads so I ws thinking of mounting the heat exchangers, slicing and then tack welding the flanges while still in place. I was thinking of using V flanges with rings as well so you could still get to the head studs with a socket. Ideas? (IMG:style_emoticons/default/popcorn[1].gif) |

The port end of SSIs is rather flimsy.

The port end of SSIs is rather flimsy. Meaning they wouldn't make strong stubs? What if I used the port ends of stock 1976? I appreciate that you are following this Chris. Trying to put together a six and keep the 4 running at the same time has required bargain hunting. And of course I like experimenting too. Haven't the er thingies to drive as fast as you do though.

By locking the two together it may cause a leak. It's a puzzle with lots of trial and error to get it right. |
