turbos on inline 6

Easy fix the- 307 chevy v8 piston can be picked up cheap ( in a forged piston-usually trw , sealed power etc) for the 250 -it is literally a drop in-pin height, rings , etc. On the 230 the 283 forged piston is a drop in . There are ten million sets of 283 pistons( forged and other on ebay etc.
It is true that some of the SBC pistons have a narrow skirt that will put some cylinder wall stress, but below 5500rpm its not likely to cause a problem.
I actually ran a set in a 250 with a supercharger- turned it 6500-7500 hard and often-ran 10-16 psi - with a 144 B and M blower on my intake - broke a lot of things - the pistons were not one of them.
I race on a shoe string budget-you lern to use a mic and read the part book fast. your machinist is your friend.
