066/394 hybrid build

[Chainsaw Jim]

Well it looks like I'm going to build a 066 bottom with 394xp top end. Here's the two candidates for the build..

I'm still trying to decide on which piston I should use...the 056 mag or the 394. It would be nice if there was a piston with a pin to crown height in between the two.

Oh my lawd!

Wouldn't you want to use the 395 top end, at least it has an intake boot instead of a block.

And Quad port transferrs

Quads

Is the cylinder bolt pattern real close?

Subbed

I love these frankinstine saws you guys build. Some of your experience and creative talent shows big time. A boot set up so u ds better to me but maybe he already has the 394 jug. I dunno but I'm excited to see it built and ran.

No I wouldn't, and I'll still use a boot.
I can take the 394 intake nearly twice as large as the 395 because of the way the 395 necks down to the cylinder. One of the 394 cylinders I have is molded straight across the entire top of the flange allowing it to be enlarged considerably. As far as the disadvantage at the transfers I'll have to finger port it or something to get the extra flow to avoid a bottleneck.

Here's an 066 gasket lined up with a piston. I'd say it's close.

Awaiting the results from this build......

Getting the cylinder bolted up with the right piston would be the easy part. It's everything else that's time consuming, plastics, muffler, intake, carb and linkage.

Good luck to ya Jim! Cool build

Absolutely. Can't wait to see it

With a head and studs the bolting down would be real easy. Might have to weld up the exhaust flange to tap muffler bolts or use a 385 muffler and washers over the tubes to hold it on.

Velly interesting.....

 

[junkman]

Am curious ,how many man hours go into r&d on something like this build ? Doing it for a living a guy could go broke real fast if do too many ?

 

[Redfin]

Curious how your planning on running a boot with this setup?

Once you figure out how to do it its just labor time after that charge accordingly and if it runs as good as I hope it does there should be plenty of customers to make it profitable
