Here is a piston swap alternative for the 250 using aftermarket 6.00" rods and 5.7L LS Chevy V8 pistons.
Well isn't the 5.7/350 a 4in bore??? the last I knew it was. so for most this will be .100 over bore. Or did I miss something in all this??
Larry, the 5.7L LS engine replaced the traditional 350 style engines in 1997. The SBC engine we all knew during the 60's, 70's and so forth died in '97 and is no longer made. The LS is still 5.7L, but is 3.897" bore with a 3.62" stroke. So its been the standard Chevy V8 for almost 17 years now, so I guess you could say that you kinda' have missed something.
