Is there a drawback to a steel crank?The TH350 will hold up fine; send it.
You know the 425 has a steel crank, right?
Nothing was done to the th350 it is a TCI Street rodder New in the boxWhat was done to the TH350? You can get 400 HP pretty easy. Cutlassefi brought a nice 10cc dish Mahle forged piston with a 1mm ring pack. Along better rods and the right cam, it will haul *ss. The 2004R will probably need a billet forward drum.
If being able to zing it as high as the heads will flow is a drawback, then, yes. Otherwise, get the lightest rods and pistons you can find, the wind the tach all the way around.Is there a drawback to a steel crank?
