    TA Performance lists 225V6 OF cap as TA_698A and the 231 OF cap as 698C.
    Any of you OF conversion aficionados tell me the diff or have a picture of both. I have looked everywhere I can think of. HELP.

    Walt, I haven't used either of TA's caps, but the difference might be the 225 cap is the original small diameter cap, and the 231 cap may be the larger diameter HEI cap.
    If no one else steps up with a more definitive answer, it might be time to email/call TA Performance.

    I've never found any difference in the HEI OF caps I've run, but most of them have been based on the 231 OF. Since the HEI for a 225 is based on the 231, I'm not sure it 'can' be different.

    Check to see if your reading it right as the 231 EF is different from the 231/225 OF cap needed in HEI. The 231 EF CAP has 6 posts on the top of the cap vs the 8 on an OF.

    There never was a HEI offered for a 225. We use later 75-76 distributors that came in OF 231 engines or convert a EF 77-82 distributor to work in an OF. The only oem OF cap is for a 75-76 Buick with an 231 odd-fire motor.

    It seems the 225 OF 698A is non HEI and the 231 OF cap 698C is HEI. Not sure but that is how I interpret the details on the TA website.

    I believe your correct. The HEI designation does not appear for the 698A. Think that pretty much answers my question. Tnx for the reply.
