I am currently working on the design of a 25, cat that I plan on building out of aluminum. I am currently tosing around engine and drive Ideas. today I am leaning more toward custom fabbing up my own drives strait out the lowest point possible of the sponsons at the transome I'll get a pic posted so I don't haveto explain. but I was thinkin of runnen 2 outdrives out the ass end like in the pic and I am at a point were I could run 2 small blocks or run one big block. What do you think abkout this?
Thanks Info I have seen your posts on hear and it seem that you know your shit when it comes to power. wink

The DCB 26's run pretty good with 1 big block.
Build a big engine and put a pulse drive on it.

I can fix you up with the engine.
I have a good recipe for a blown small block also if you want to do two.

Thanks info Sorry to throw shop talk at yah. I'm not sure but I think on big block would be the way to go plus it would leave plenty of room to get around to it to work on it. but on the 2 small blocks you got that harmony of 2 engins purrin out back like yen and yang but them you have the headache of sincronizing then as close as possible. once agoin thanks for your .02 :)
