Wiesco pistons

AMC built 390`s & 401`s to go racing, with forged cranks, and stronger blocks, capable of 4 bolt mains.

The nodular cast crank in the 360 is very good but is not as strong.

If your racing 7000+ rpm use the steel crank, ideally in a 390 or 401, or like me stick it in a 360 and get a "pretend" 390.

As Trader said people misunderstand the limitations on the 360 and in fact most street use will be within the cranks capabilities.

The guy who put my 360 together was a Ford specialist and built custom engines for AC cars at Brooklands at the time, all of which had steel cranks rods etc. so never having done an AMC before he warned me that the cast rods "were like matchsticks" and the "pistons and crank are like glass"

So he left me terrified of over reving it. He did however concede that the AMC head was nearly as good as a 302 Ford, high praise from a Ford guy :-)

Faster than the 383 Roadrunner, the  383 Rick Jones Special.... 

Along these same lines, just curious what others have to say about press fit piston pins vs floating pins. Probably less money to press than install the floating pins but not sure which is the preferred method. Maybe the more experienced guys could give a little insight on the subject.
