My hero, your the man, now I will Google the pin weight, and be able to talk to my machinist and give him the info. Hopefully he has info on my combo on file and will tell me the size drill bit he uses to remove weight. And where.

Good question, I been traveling, but the saw and a bunch of other stuff should be waiting for me when I get home...you should see that band saw, it's a beautiful compact unit , where you just bring the blade / motor unit straight down, (it's swings down on a precision hing and cuts anything just the way you grip it in the vise, so a pistons crown will meet the blade, straight or crooked, depends on me how / where I clamp it. I will be home next week.It's been over a month, did the band saw blade get dull? Sandpaper lose it's grit? chewing gum soften up from heat?
1st off it's you're not your.Your to smart 340six..be quiet....unless you have some specifics about scats 4" forged crank . How much does the machinist remove and where, if useing 715 gram rods and bolts and stock TRW Forged flat top pistons weighing??? How deep and wide are the holes....or, hell I would just be satisfied if someone could give me the accurate grams of one of those pistons/is .030" over with rings.
Never doubted you are smart. Hope your memorial day gets you rested and stronger. Sincerely Jesse1st off it's you're not your.
See proof i am smart.
And i have them in here stock steel crank. Yes the forged TRW high compression one's that are above deck. And with closed chamber heads. I had a real machine shop mill them. And shoot peen, resize the rods with ARP bolts, rebush small ends. Balance Crank. The closed chamber heads,are 52.5cc.
The way YOU are doing it is a hack. Do it once do it right.

Follow up ..will be sometime next week when I get home.I prefer a Harbor Freight cut off wheel to do all my critical work. Good luck with your project and please give us a follow up.
Thx for the motivation. I decided to just use the 3.79" crank with TRW L2405F pistons and thin head gasket .028", and speed Master Aluminum 65cc closed chamber heads...uneducated guess will put me @ a hopeful 9.5- 9.8 cr...I am sure some expert out there will correct me on this statement.You need .187 or so for material thickness on the top of the piston if I remember correctly. This was a set of TRW's but it's been 25 years.
Make a simple fixture to keep it consistent and way to scale your pistons. It won't win awards from most but I did it and that motor is probably still running today lol.....
Does this help you any?

Will display my band saw next week, cutting the crown off some cheap $15 new pistons I got off ebay.It's been over a month, did the band saw blade get dull? Sandpaper lose it's grit? chewing gum soften up from heat?
