I had to get some longer bolts than what FTI sent me for my latest converter. I just went to the bolt store and got some grade 10.9 flange head bolts the correct length. I have not installed my dust sheild so I can't comment on the clearance but thanks X for the heads up.

Conversation with ARP:
ME:
Application is a 2005 LQ4 6.0L LS series GM V8. I have a TCI flex plate
part#HP399753 (Chevy SFI 29.1 Approved Flex plate) I previously had an OEM dished 4L60E flex plate, the TCI flex plate is thicker, and flat.
This requires longer flex plate bolts. I am wondering if your flex plate bolts part #244-2901(Gen III/LS Series small block .880 M11 x
1.5) is correct for my application? I do not know the pitch/length that I need for the TCI flex plate so I was hoping you have worked this issue before.
Thanks,
Chris

Hi Chris
The LS Chevy uses the same length fastener for the flex plate and flywheel. They are 11m x 1.5 x .880 long. That is the only one I have like that. How much longer do you need yours to be?
Thanks

I am being told I need M10 x 20mm in a 12 point. I can't verify this yet. Do u have that size?
ARP:
Chris
Have you re-drilled the crankshaft holes to a different size from factory?
RonF
ME: No. The flexplate is a TCI flexpalte not OEM. Not sure if that helps.
ARP: Chris,
The thread size will still be the stock GM. As a rule most after market flywheel or flex plat manufactures will use the same as the stock length bolt. Take your stock bolt with the new flex plate and see if it will fit.

Didnt really get an answer. I wanted to have ARP bolts in hand when I install, not try to figure it out that day. Maybe the TCI ships with bolts. Oh well, find out Tuesday.

Chris, it would appear from your correspondence with ARP that the two of you are not on the same page so to speak. What he is telling, which is true, is that the flex-plate to crankshaft bolts (part # 244-2901, Gen III/LS Series small block .880 M11 x 1.5) are correct for your application. But I believe in reality you are asking about the torque converter bolts, which would be (part # 230-7304, 10mm x 1.5 in., 12-Point, Steel, Chevy, 200-4R, 700R4, 4L60, 4L60E, 4L80E, Set of 3). In my experience you will have to verify the actual length needed for your specific application and that ARP doesn’t actually have a pre-packaged bolt kit in the length that you are going to need. I do have the TCI flex-plate, but I’m using it in conjunction with a PI Triple-Disc in a standard 4L60E configuration. The above mentioned ARP 230-7304 bolts were not long enough in my application, so I just purchased hardware store Grade 10.9 bolts and cut them to the proper length. Also, unless you can find a bolt with a built in washer, you will need to take care in paying attention to how far the head of the bolt protrude towards the rear engine cover. If they are allowed to stick out too far they will hit the cover.
Good luck with your install!

1Bear,
I was going to look into converter bolts as well but right now I was trying to find the flexplate to crank bolts. I have ARP bolts in there now but assume with the thicker TCI flexplate they won't be long enough. I dont have an issue going down to the hardware store to get the correct size and pitch and cutting them, the problem is, the town I'm in is about the size of a postage stamp. I will have to see if the local place carries grade 8 or even metric in my size.
The converter to flexplate bolts I currently have should work fine. In theory.....
EDIT: I am using a PI triple disc set up for a 60E flexplate (3 bolts) and am also using the stock dished OEM 60E flexplate. (now broken)
