Rick- I didn't picture you as the type to hang out at the boring bar. I figured you were more for the high-class joints.

Well, no guts no glory right? Took the plunge and the first squish band I cut was on a $300 390 Cylinder! LOL. Got er done though.

Will,

how much did ya take out?

IF 'NO' how did you figure?

Started with .020", don't want to go nuts my first go round. I figured cutting the squish band will have more effect on compression then a popup.

Just port your 385.

 

[jropo]

There's currently no aftermarket 390 top end kit and
putting a 395 top end on a 385 case would be more work than its'
worth. You'd be better off to stuff a 3120 top end on a 394/395
(Which I've actually seen in person.)

Kinda what I thought but ya never know.
OOOOOOOOOOOOOOOOOOOOOHHHHHHHHHHHHHHHHHHHHHH!!!!!:hmm3grin2orange:
Now your talking!!!!
Fast/slow?
rpms?

Thanks Rick!

 

[parrisw]

Doubt it Will, at least not for a good while. They don't even make an aftermarket piston, at least that I'm aware of.

Typed on my lappy from a hilltop while camping with a coupla bourbons up my belt!

Nice, wish I was with ya AL.

Oh, well. BB's are nice to play around with. But I do like having OEM to run.

 

[jropo]

Nice work!
I was wondering what you meant about squish band now I see!

 

[parrisw]

Thanks.

Yes, squish band is the area of tight clearance between the piston and combustion chamber.

Just port your 385.

I suppose I could do that, It would save me some, but I would always wonder about the ported 390.
Go big or go home. If I gonna do this might as well do it right!

I agree, but if money is tight??

385's can be a real good runner ported, you'd be surprised.

Hey will is right,,,,, those 385's are no punks,,, they mod up very well,,, but if you have to have the 390 then save your money,,, get one and then get it modded,,,, you can always sell the 385 P/C and get about 1/2 of the oem 390 p/c cost back
