Frankenstein motor for bottom end snap

[Jakobi86]

I bought a sn a few months ago with a 6m6 bottom end and what I believe to be a 61x top end. Has protec head, psi ex manifold and pipe. Msd enhancer. running a dual carb setup with I believe 38's. And some intake manifold that I'm unsure of. Prop is stainless 12.8/14.5 I believe when I had it out. What's going to give me best bottom end assuming I keep the head, pipe, ex mani, and prop? Wondering if I should run the dual carb or look for 61x cases and run single carb or dual on the 61x case???

Have any pictures? Are you sure there not 62t cases? It has 6m6 stamped on the bottom and 62t stamped on the top from the factory

No pics right now,
But the case is stamped 6m6 and is silverish blue. Didn't see any markings on the topend but it's a dark blue/green color with no metallic in it. When I get home I can try to take a pic. I know I bought a 701 flame arrestor for dual carbs and the spacing is too far apart for my setup, if that helps at all...

It's stamped 6m6 on the bottom and on top of
The cases. The dual intake manifold is from protec

Im building my first superjet so im no expert.

But if you were looking into buying new cases wouldnt it be more beneficial to buy 62t cases and utilize your 61x topend. Everything should bolt up you would have to check on manifold though im not sure if 6m6 manis and 62t manis have the same fitment.

Also i have never ran a full 61x motor or any superjet platform before so i cant give you first hand experiences
