can the trw L2316F pistons be milled down to make only somewhere around 9:1compression or less with 66cc Heads`and still live in a supercharged 340? or is this a total waste of time and money?

i would do it if you already have the pistons.
The top on those chunks are 1/2"!!!
If you dont have em use the 72 and later pistons.

If you decide to mill the 2316Fs, consider leaving the quench side as is and mill the non-quench side down. As stated, the top is around 1/2" thick so a lot can be milled off. That would also lighten the heavy slugs as well.

those pistons sure are thick!


found #2 main being deeply grooved wish is very odd considering this motor always ran without alot of knocks and ratling it had the sound of loose clearanced pistons but nothing like that it realy surprised me tried to make a good pic of it but could not get a good one and the crank is already cut .020/ .020, and #2 cylinder wall has some deep cuts in it also i almost think the bore is cracked and that killed the piston

me also but i seriously think this block is finnished for real have hade a good look at all the bores and thats not the only one that seems to have started splitting this particular block have been a raceengine since sometime in the early 80īs from what i understood from the previus owner so i think its time for it to go to rest,its been beaten on with heavy trw pistons for a long time
but i have found another block and crank for sale for a fair price so now im just waiting for someone to either buy my dailydriver or for payday so i can go buy it:) unless i fall over a cheap bigblock or newstyle hemi

so now i have found myself a "new"block and crank and also some 2316F pistons all for a somewhat good price

will i get away with milling those pistons 0.100" or even alitle more or is that just to much? looking at them the valve pockets are way deeper that that and that would still leave 0.250" from top of piston to the top ring
this is for a litle pumpgasmotor runing a lysholm twinscrew blower

thanks

Don't you have E85 in Sweden? If you have high compression, it would probably be ideal with E85 and a supercharger. Just something to think about (eventhough making pistons lighter is a good plan).

around here in stockholm its not a problem but i noticed that it was sold out alot when i have been out of town last summer so im not realy sure i want to take that step just yet but it has been on my mind a few times
yeah geting alitle weight out of those heavy chunks feels like a very good plan

ok i know this may be a very old post i started,but my build is not going very fast but at least i keep the build going

just in case someone else does a build like this and need the info, i just weight my milled of 2316 pistons and after cutting them 0.080" they are still ranging betwen 697-700 gram didnt think they would have been that much heavier than my old (cant remember part#) high compression TRW pistons with there domes milled of, sure the old ones where lightened some but they where just 631gram.

hope it helps someone
