I have a fast 90mm intake that has had a couple of repairs done to it(had the outlet tube that leads to the brake booster expoxyed back on and the same on the inlet tube on the front). They seem to be completely sealed and they fit exactly like they did when it was new, except for the fact that there is epoxy there now. Would it be ok to use this intake on a stock bottom 346 with full bolt ons, cam and nos? If not, would a the new Fast 92mm upper shell fit on the 90mm bottom shell? Any info would help. Thanks.
