ms460 big bore carnage

[Mastermind]

Just had one dropped off to look at today. Any tips??? [emoji6]

If it's the non-strato version they can be made to run very well. Do the usual widening of the intake and exhaust, lower the intake floor a few degrees. Advance the timing and open the muffler up good. A little thinning of the throttle shafts and screws.....and it will surprise you.

I did one with a Tilly from an XL12, and external transfer ports. I fly cut the bearing pockets and raised the crankshaft up about .050". That allowed me the do a pop-up

I was mainly using the kit to practice porting with cause it was cheap. I didn't figure it would last. It was a fun build. I am going to sand the transfer out of the cylinder and try some more tweeks to it to see if I can get any more out of it. It's just for personal playing. I like having fun with it and not having the worry. I am wanting to try one of those cross performance kits on my 064. You still having good results with them???

I have ported a couple am 064 cylinders and both were very nice and ran well.
They also have a decomp hole if you needed it. I didn't use the bb though
Both were standard bore

What does fly cut mean?

 

[Cigmaker]

Did someone say pop-up!

I'm probably using the wrong terminology. I cut the bearing pockets deeper into the jug to raise the crank.

I figured you did the ol @chrisPA trick. [emoji33]
Thought you had a cool way of doing it to show us...[emoji22]

 

[Mastermind]

I used a fly cutter.

 

[MustangMike]

See, now I would have said "to drop the cylinder"! Does you method work on 029s also?

 

[Mastermind]

Well you ain't dropping the jug. You have to offset bore the bearing pockets, then mill the base, and that raises the crankshaft in the engine.

It's far more trouble than it is worth.

Is that like a fly swatter with blades? [emoji851]

I'm smelling what you're stepping in tonight. Troublemaker

 

[jake wells]

so a pop up would be better than trying to lower the jug?

 

[jmssaws]

You have to lower the cylinder or in this case raise the crank to use a popup also.

I happen to know an expert at pop-up port work if help is needed. Brad can you hear me? Randy really doesn't know what he's doing.
