Default LQ4/TH350 - Torque converter question

Got an 01 LQ4 being mated to a th350. Would any th350 torque converter work for me if I elongate the bolt holes? I was looking at this converter...

TCI 242101

PTC is far better. TCI is what I would call entry level. Its OK if you cant afford the better converters.

that's an awfully loose converter for such a torquey engine and a non-lockup transmission.

Yea but Kenny has far surpassed TCI since starting his company. And the TCI is nowhere as good as the PTC. I also have run both on high HP cars. I have had several TCI converters fail, But have not had a PTC fail once. Plus I like the service PTC gives you.

So, just grinding out the bolt holes is ok? Even on a big convertered/high hp car? Figured you had to have a conversion flywheel. I've only owned a Yank PT4000 and a 4400 and loved both. Put TONS of miles on both. Had local cars with "cheaper" converters not run/perform near as well as the yank. But that's been several years ago. Converter choice is a big decision!

how so,show us some product information detailing that(beside the problems of one person)tci has been in business for decades they must be doing something right....what ptc did was very good PR work by getting their product out there and offering optional(i.e. anti ballooning plates and such)a little cheaper than other companies....and made the customer feel special by offering a tech info card so the customer was thinking he's getting a custom built conv. but it was usually a off the shelf part number and that was just smart business..but far as better,i'm saying you cant go wrong with either conv.......

thats what i did,who knows i'm going to take the motor out soon so we will see if it has any damage....but far as conv. choice you get what you pay for,but you'll be happy when you see the price on a turbo 350 conv. compared to how much they cost for a 4l60e.....lol

I am relating my experence with both companies. And I have had trouble with TCI and none with PTC. And PTC has built me around 10 Different converters for several of mine & my friends cars. Not here to start a pissing contest with you. Just stating the facts.

I'm doing the same lq4 with 350 trans. I got the hughes flexplate and adapter. I just ordered arp bolts part number 244-2901. Call hughes and arp to verify part numbers. I had a new conv from another setup so i figured I'll stay with what I have. My conv is a trans specialty 350.00 brand new, why buy another one. I'm not trying to run 8's or 9's just 11's it should work for that.
