a 370 is just a punched out 6.0 block...if your putting together a foraged rotating assembly, why not punch it out anyways...6 cubic inches isnt gonna make a difference in dd or gas mileage...

maybe your talking about a 408?(4" stroker crank in a 6.0 block)

A 6 litre and a 370 are nearly identical performance wise. Are you saying go this route vice a stroker? Or are you asking the difference between a 364 and a 370?

Do they make a stock 6.0 bore forged piston. You might as well just do the 370 since pistons are readily available.

only gasket i bought new was some cometic .040 head gaskets.. every one will tell you to buy front and rear cover gaskets, water pump gaskets.. jfyi when my 370 runs i DD it, and its gotta big ole healthy cam and 4.56s.. one thing thats daily driver friendly to one person may not to another.. once i finally got mine tuned it was a blast to drive around..
