And like your saying SB a 325 C.I engine isn't making allot of velocity thru a 2 inch primary. I can't remember exactly but it's at least 2 inches

Here ya go SB, I forgot I had them in the bed of my truck.

They have a 2" Primary




The total length from where the 4 primaries come in to my tip 26.5" (I extended the collector all the way to the tip)



I added about 14" to what he originally sent me



Drop from the top of the collector to the bottom of the tip is 16"

I'd be suprised if 2" as their standard bbc is 1 3/4" ID.

Edit in: beat me with above post with pics. Wow ! And...WTF ! 2"

My header gasket is 1.875" and just clears the exhaust ports in my heads. Also, my heads have had a heckuva CNC port job done on them.

LOL I know ain't that crazy! Hey Corey did you get yr sea pump braket fabbed up? I'm curious because I'm going bravo this winder and I'm trying to figure out what to do on the sea pump. I know the cp marine one is a option but thought about a crank drive to.

Yep, I ended up using a brass Jabsco pump bolted directly to the crank. Then fabbed up this bracket. I bolted it to the block where the factory A/C bracket goes. It aint the prettiest, but I didn't want to go all out till I knew it would work. If everything seems fine with it, I'll CNC a new one this summer sometime.

Any updates? I love this thread.

Yep, got the exhaust all dried up and looking and working the way I want it. I cut the old tails off and welded new ones on with -AN fittings inside the transom.




Then, after measuring and remeasuring for a couple hours (and a couple of beers) I got up the courage to cut the holes I the transom for the thru-hull fittings.




I sealed the holes with epoxy then siliconed the crap out of the fitting and got it installed.











My first real trial was this past weekend. We had the annual Checkmate Owners Rally at Lake Cumberland. I was able to put about 2-3 hours run time on her. Didn't really get on it too hard, I was mostly just checking things out and shaking it down. Everything seemed to be working pretty well. I am going to have to do some tweaking to the coolant crossover system, but that's going to be easy. Once I get a few of the little things figured out, then it'll be time to start playing!!!
