066/394 hybrid build

[Chainsaw Jim]

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.

I'm thinking 394 muffler with a welded on flange. Not entirely sure yet.

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 ?

It depends on how much machining and welding needs done on any build. I've spent more time rebuilding some stock saws than I've spent on building a modded saw.
But this isn't a build for a work saw. This is going to be a build for the 6 cube racing class so it may be the only one I build.
I make my living running my shop on a normal scale and I work on these things in between jobs.

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

I'm going to shape it like I did this one so I can use any boot I want.

Looks like a good way to use up your spare time.

I'd seriously rather be fishing.
It would be a good dream to have a large fishing boat with a little saw shop bench on it so I could do both at the same time. Lol

Amen to that!

Gonna cut the flange off the cylinder?

I think he's grinding the outside of the intake down to fit a boot over the top

I was thinking about the flange on the base,be easier to clear everything with it gone.

I smell what your steppin in now

Yes. If I was going to split the case I'd relieve it in order to leave a front and back on it for alignment.

I found a good muffler that I think will be an easy mod to fit.

I like it.
What's the intake angle look like?

Amen to that!

you would probably just kill the fish anyway.

every single one of them

 

[jmssaws]

A aftermarket 056 piston would probably be better than a 394 or 5 piston,there so heavy and long.
Depending on lots of things but a 66 bb piston could work.

Bahahahaha........,you have a good memory David.

I haven't ground on it yet. or are you talking about stock shape?

The angle that the boot has to hook on the cylinder once bolted on.

Doesn't the intake stick straight out instead of a upward angle?
Might be hard to get one clamp on without some cutting and welding.
A 084 neck welded in on the right angle would be groovey

An 066 bb piston with caber rings would be the best option for the least amount of modding. it may actually be a perfect fit with a gasket. The 394's taller 4.5mm difference allows you to grind the squish band about 1/8 inch wider and the fatter gasket that would be necessary may help increase case volume and raise the intake floor if it is needed.

It has an upward angle too, just not as steep. It'll be close to a perfect match when I'm done reshaping it.

I've got an 088 intake flange that I cut off sitting on my bench for a rainy day

 

[Chainsaw Jim]

I might even use a mikuni boot like this one and use a WB or HL carb.

Anything goin on with this build Jim? Interested to see how it's fittin up.
