Nope not true,get the right flywheel "0" balance, neutral. Cutting the weight off might ruin the engine,or shake your teeth out :P

Zano, You are being given alot of conflicting advise. I wuold not just cut the weight off and keep on goig. I do not agree with the way you were told to set the convertor up either. Is this a racecar or a streetcar. I have put a convertor in atleast 50 times with no problems. Let me know the answer to this ouestion and we will strat there. I have never seen a convertor with 6 lugs on it, it must be a street convertor. By the way if the flywheel is bent i wuoldnt use it anyway.

i'm glad you ask about the 6 flanges i just went and got the part # from the box go to tci.com part# 251050 shows the converter i got i never really read about it before i gave them engine spec sheet they picked it but i just looked it says 4 or 6 bolt flanges take a look if you don't believe what they say give me your email i'll send you a picture tomorrow when my boy wakes up i don't know how to send pictures . tci said that 1/8th inch gap isn't enough to worry about. when i squeezed it with my fingers i almost got the converter flush with the flexplate. the big thing is the externally balancing it will take me 6 hours to take it out no room its in a willys i'll call manufacturer on friday if i have to i'll take it out but i hope they say just cut off weight thanks zano

With GM anyway, Ive seen alot of them with 6 lug converters, most were diesels, and you can get new converters that are 6 lug, I've seen them mainly for the tractor pulling crowd. The 4 bolt they're talking about is normally Ford/Mopar.

It's TCIAUTO.com

Hey Zano.Have to agree,do not just blow weights off,combined with the fact that your flexplate is bent,I would say replace it.Although I have blown weights off many 400 flywheels for 350 swaps with no issues,these were grocery-getter customers with 200hp engines that rarely saw more than 3000 rpm.Definately not advice for a race engine.Hopefully after you replace flexplate the ears will line up perfect.(they probably will)If they don`t ,we have a saying up here,"it is what it is, deal with it",meaning don`t lose sleep over it,if the converter is new, try to get a replacement.If you are STUCK with it,don`t go out & buy another one (unless you are rich) just shim the ear in question enough so you don`t put strain on the flexplate & everything is even & happy.Provided you have the correct spaceing between converter & transmission,it will not become an issue.

flywheel
 
Zano just get the correct flywheel and don't risk hurting the engine.
Is it worth the cost of a flywheel to risk having to fix a hurt motor?
