  2. In and effort to reduce the spam on the site, several years ago I had went to a program where I manually approve each and every new registration. This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

    Got a good deal on a TA SPX square bore intake.
    Need to adapt to a dominator carb.
    Should I modify the flange or go adapter spacer plate.

    I would modify the intake....any adpater the wont totally butcher air flow will not be short....hold clearance will for sure become a big issue

    Yes,
    That's I was thinking too.
    I will bore out the flange & use a 1 inch dominator open spacer.

    looks good ...that cloverleaf flange on the out of the box 4500 spx isn't that great,...the larger plenum with the runners more exposed is better imo
