Degree your cylinder.

A good 262 cylinder is one that cries for a popup piston.

You'll gain compression and intake. The only two things you need to turn a great saw into a greater saw.

You can adjust your no gasket squish easily that way as well.

Here's the numbers I got with gasket and meteor piston my degree wheel goes to 180. Exhaust-103
Transfer - 124
Intake - 73

 

[Johnmn]

No gasket 105, 126, 70

Here's my setup

 

[Johnmn]

I also have two base gaskets one is .020 and the other is .035 thick. Timed with the .035 thick gasket. Probably will use the .020 gasket

No gasket 105, 126, 70

No gasket intake should be lower. Typo?

Whats squish?

 

[Johnmn]

That's what I thought too but I checked it twice. I'll check it again tomorrow to make sure. Haven't checked squish yet

was that Mahle timings Mike?
Its long time since I timed KS jug but thought TR was over 120°

 

[rattler]

Yes Sir it was.

48ZN15 jug I guess, both old Mahle and KS had higher TR timing.

 

[Johnmn]

So I have read lots of different options on transfer height anywhere for 116- 126 is there a go to number or is that up for debate?

I had a few like that. Hence my popup statement for someone not adept at porting.

Sounds like 10 from the chamber and a 20 popup with the appropriate base cut would make that scream Mike.

I agree Al it would make a strong saw. As far as the uppers I left these at 117 swept them back towards the intake a little and that was all I did to the uppers.

Yeah. It's so nice when you get a jug that comes out perfect on the transfers stock.

I recently did a 272 jug like that. The transfers were dead on after I used the numbers someone here gave me

 

[Johnmn]

Never did check squish yet but my final numbers are
103.5
119
72
Hopefully that works, I'll post some pics later and as I go.
