    Rated 5 out of 5 by from TCI flexplate I bought this as a replacement upgrade for a o.e.m.flexplate that cracked. I am running a T400 TCI trans. with 2800 stall 10" torq. converter in back of a 350c.i. 300hp motor. All is well.

    Thanks for the last answer - but, I'll ask again "Which TCI flexplate has 10.75 and 11.5" holes, 168 tooth, internal balance for Big Block Chev applications?'.

    Asked by: walt z
    TCI does not have a converter with those specifications.

    Hi, Normal 'dual-pattern' flywheels for Chev have 10.75 and 11.5 bolt patterns. This states "10.75 and 11.1". Is that correct? If so, which TCI flywheel has 10.75 and 11.5 patterns in 168 tooth/internal balance for CHEV MarkIV BBC?  Thanks.

    Asked by: walt z
    The LS engine uses a 11.1" pattern. This part number has the 10.75 & 11.5" patterns - Part Number: 555-601071
