C4 Flexplate question

[brands5.0]

I have a C4 In my car and i bought a super expensive PA 50 oz. I am now building a "0" 364 can i just cut off the counter weight. it makes sence i am looking at a 28 oz and the 50 oz and the weights are in the sam place ?? seems like i cold just cut it off and it would be fine

Let's see, you're spending several thousand dollars on a new engine and you want to just cut the weight off that flexplate and go with it?

Not to sound liek a jerk, but....

Ummmm....... no, I wouldn't do that if I were you. At the least take it and have it done by a mahine shop where they can reballence it after the weight is removed to be sure it's zero balence. Or sell it and buy a zero balence flexplate.

You said it's "super expensive", but a new flexplate is like $225 and your block alone was about $2500. Plus machining, the cranks, rods, pistons, etc....

Does it make sense to skimp on a $250 part when your spending several thousand? Not to mention it's a pretty importent part. Vibration will kill an engine and seriously hinder performance.

I had to see this!! HELL NO!! you cant just cut the counterweight off!! Get the correct flexpalte and have it balanced with the rest of the assy..... you DID get the rotating assy balanced... didnt you??

Just me.......................

The motor is not built? just trying to see if i could reuse an existing flywheel.. I have a PA C4 and when i installed it the flexplate i had wouldnt quite fit there was at least a 16th gap so pa set me one that was a 16th deeper if i have the same problem with my new motor ill have to buy another custom one.
