MTC or Wisco

bottom line is cast is more brittle than forged...
cast is cheaper to manufacture....so cast is oem....
forged be the way to go if you have a choice....

My dad put Nitrous on his Alfa Coupe back in the 80's. That motor lasted about 2 seconds on the gas with cast pistons.

it depends on who made the cast pistons just like anything else.i bought a 415 smallblock chevy kit years ago from HYE TECH PERFORMANCE in california(thats where the HYE TECH UTILITIES spelling came from)anyway that motor had keith black silvo-lite(spell check)pistons in it which are cast.between 10.5-11:1 with the heads i was running, .510 lift cam biggest quadrajet i could lay my hands on at the time and an eldebrock dual plane and a set of short headers in a get this :evil: :evil: :evil: 1961 chevy 1 ton 4x4 dually dumptruck with 4.56s and a locker in rear with a truck 4 speed,that freaking thing was fast!:laugh: anyway i beat the hell out of that motor for a few years in that 7,000 lb truck then a friend stuck that same untouched motor in a 64 chevy station wagon hes been beating in the 1/8 mile for 2-3 seasons !cast pistons can take alot of abuse if they are put in a motorthats put together right.

To answer the original question, I'd rate MTC over Wiseco. MTC is higher quality, IMO. Plus they will custom make anything you want.
