    Default Those little nubs on the suction housing.

    Can I grind the little buggers off? They're getting the the way of the flywheel cover for my 4-point mounts.

    Background, 74 Kona, was olds powered (3-point) going to a 4-point BBC, Berk JC punp.

    I'm dieing here guys. For the past year if it's not one thing it's another. I've back burnered the boat so many times for stupid things and now I have everything I need to get it going and this happens.

    I think you mean the 4 nubs on the Intake, not suction housing. If you do, those are the backside of where the bolts run to hold your rock grate or loader. I'd notch or grind down the flywheel cover before grinding on the intake of the pump.

    Yeah, those nubs. It looked like the rear mount for the olds was hitting/rubbing on them so I wasn't sure if they were there for the engine to rest on or what.

    X2, what housing are you using? Grinding those "nubs" down could weaken an important area of the intake.......Ray

    It's a cast set I purchased a year ago from another forum member. The front has Guardian cast into it and the rear is unmarked.

    Glenwood made the "Guardian" series, and the rear may have a name cast into the inside lower surface......I see no reason not to customize the lower side of the housing to clear your jet......But, why is your motor so far back, or so low? Or your jet so far forward? Those housing have been around for decades without interference at that point........Ray

    It comes from a host of things. I have an enclosed engine compartment. I had the Driveline turned down by my machinist to match the 3-point olds length which I then used to align the BBC. Had I left it alone I would have needed a half inch more compartment then I have because the chev driveline I procured was 2" longer then the olds. I went with the same lenght of the original so I could use the olds bellhousing to triangulate the mounts fot the chev. So far it's worked except for this little issue.

    No big thing. a few more modifications to the flywheel cover and I'm golden. Worst case my neighbor is a welder and is set up for aluminum on his wire feed.

    I should note that I have a rear 3 point mount for a chev that I used to set the rear feet for the 4 point. My alignment came out perfect, it's just the cover thats being the bitch.

    The nubs on my intake are ground out a bit to allow the flywheel to set where it needs to on my BBF......now this was when I was running a 3-point set up. I am going to a rail kit and the engine is moving forward and my drriveshaft is longer now.....

    I through bolt my loader bolts and double nyloc nut each one....Not sure the intake is going to break apart but I am no expert
