a "375" usually ran dt 175mx pistons
but a 2 mm o/s 350 is about 375
me i'd stick with the standard oversizes which i belive go up in 0.25 increments when you get to 2mm or so the liners get a bit thin
and with big ports ,as most o/s motors are get a bit ..er quirky
if you want got 2 sets of 2.5 o/s barrells i'd happily swap you for your .5 o/s ones

Okay so plenty of life left in them yet then. All are 4lo
Ta for that, did think 375 has dt 175 pistons will get barrels measured, have another 2 sets of 350 barrels that i will have to get measured.
Cheers Tim

I can get up to 2.50 on 350 pistons then you go to DT175MX pistons . But after 2mm the liner gets very thin and its dead realy and they get to hot and seze up more when you go to 250 and the biger 175.
