I like the green pullies, I'd do red to match mine, but after chasing a belt squeal for years I'm gonna skip that mod. I do like the look though. I think a new alternator will fix it, but haven't gotten to test yet.

the boat is a 312 and not a 292 they left the factory with the 6.2 454 and 502 power unit the boat has the same width as the 353 and 382 I do not believe that we make 2 boats make different stringers , the difference between a bbc and a sbc is the width

Because they left the factory with BBC means nothing...the fastech line is notoriously bad for have no space in the engine room.

look at an OL or cig...you can have a family party in the bilge and still have room for engines.

hahaha!!!

I dreaded wrenching on the 292 and I was only 22 years old when I owned it. Had to be a contortionist to reach anything. spark plugs were particularly fun!!!

Small blocks and big blocks use the same motor mounts in the same locations on the engine block. It is possible though that the engine spacing may be a bit wider on a BB boat. I am sure you could have some tails made if the exhaust doesn't line up correctly

There you go,285. Looks like you are clear to transplant. Post some pictures along the way and good luck. Welcome to the Formula flock.

My hull is set up for the factory bb exhaust locations , ie: wider . I have 6.2s it came that way. Engine mounts and crankshaft centers are exactly the same, GM had that all figured out. BB & SM Chevrolets will align the same in ANYTHING, car, truck or boat for that matter. Crankshaft center to mounting pads is identical on either engine. The big blocks are just taller in height. Your exhaust flex hose is located on an outward angle from centerline Thunderbird / Formula didn't care what engine package was going into the hull, they just cut all the holes universal because the Silent Thunder system wouldn't line up otherwise. Call Vintage Formula Tech Line: 260-724-1413. Scott Smith is the most knowledgeable Formula guy you can talk to. I have an over 30 year business relationship with him. He's running around somewhere, ask one of the Tech guys to ask him, Scott Ransbottom, Bryan Boehmer, Chris Everett, Lisa Clifton or Karen Reinhart. Better yet and easier Email them: [email protected], they will respond with the information or answer any questions you may have. Sarah Hillman or Tonya Hamilton director of communications will definitely respond. Have your HIN # for specifics. Walter Fletcher
