Exhaust before polishing

Damn good work
Whats the trasfer timing like?
Decked cylinder much?

Thank you sir. Exhaust is at 103* @65% of bore, transfers are at 119*, intake is at 79.5* and widened a bit. I dont remember the exact amount taken from the base band but I believe @David Young took .030” from the band, .040” from the base.

All done. Right around 12 hours in total of tweaking this cylinder. Tried to get everything as symmetrical as I could. I think it’ll run decent.

I got a 353 with 104/120/80 and triple port muffler, everyone in the crew reach out to that saw before anything else. It needed a stack and uni filter to come alive

It's either a 266 or 630 cylinder. I'm guessing 266

This KS gave me fits. The cutter heads kept skating and diving.

Looks good to me bud, keep it up. Polishing to a mirror finish doesn’t gain anything worth the time it takes to do it in a saw imo. Unless it’s the exhaust port to keep carbon from building up.

Nothing wrong with that. Just make sure you have a good bevel.

Thank ya Randy. I usually spend a good amount of time just chamfering/beveling. Snagging a ring is the last thing I want to happen after I just bought a 180.00 top end lol.

Thanks Mason. Ive found that fine polishing doesn't really add anything as well. Instead of progressive sanding the exhaust like I usually do I just went in with a single cut bur and made everything somewhat shiny.

I forgot to mention that I did an even lower exhaust and somewhat short blowdown. Lower transfers were left completely stock, intake was left alone, (79*). Most of my time was spent in the uppers to get them aimed the way I wanted them to aim and such.
