Ls with b16 rods and pistons?
I have come to understand that b16 rods will fit an ls crank. I was thinking this setup (ls motor with b16 rods and pistons) would make a nice low compression b series budget build but I cant remember ever hearing this done and was wondering why? Cr too low? Gains not worth the trouble? Using a cr calculator I found it should come out to around 8.7:1. I figure you could make 300whp a good bit safer than with the stock cr for pretty cheap since most of us have all of these parts just laying around.

would also give you a fucked up r/s ratio and piston to deck height.

a B16A rod is 3mm shorter than a B18A/B rod.... :1
buy real pistons/rods...

Re: Ls with b16 rods and pistons?
Well Im just saying if you were to have an ls block laying around and some b16 pistons and rods also laying around why not? I guess it really wouldnt lower compression whole lot but 4-5 points in c/r adds a decent amount of safety basically for free if you have the parts just laying around. I guess the messed up r/s ration and piston to deck hight is the main problem which is what I was wondering. Thanks for the input.

like 6:1 compression.

well if your confident in doing it then do it. Has an engine builder deck height is about has important has things get in building motors. Thats all.
