Simple question.............WTH happened here...............

Obviously a factory screw up unless somebody knows something I don't. The standard Bravo Exhaust Hole distance of 27.328 center to center is
off by 3/4" per side. This is what caused allot of head scratching during this project as I could never get a straight shot with my tubes. This made welding everything up a real challenge and cause me to add allot of minor angles incorporated into the project to get it straight out the back.

Just curious to see if this is a one time oooppppps or if that the way they all are ??????????????

Try swapping risers left to right. I did it and it was much closer.

I just measured my center to center exhaust cutouts on the transom. 29 1/2

Possibly the holes were drilled for a 502 ? When I removed the factory 496 and put in a 502 I had to move the exhaust holes approximately that amount to get them to line up.

I had to go back and find a picture as I did this about 10 years ago. It looks like it was a little more than 3/4"

Thanks guys for the heads up on the holes, I was just curious. Too late to make any changes anyway as this project has just about come to the end.................

Decided not to powder, just ran over it with a 3M Fine Deburr Wheel and riser now has a shiny satin finish. Got to tidy up a few odds and ends and this exhaust mod is done.

I hate these toilet seat flappers with a passion, "BUT" my options are slim right now so they go back on for the time being:

....And yes.. apparently, Velocity DID employ blind monkeys to cut their exhaust holes.....


When I went from the 496 Mag to a tall deck raised exhaust port big block, I had wedges made to raise my tails which is to be expected...

However, I also had to slot the mounting holes in the port side riser as THAT tip was outboard over an inch !
The starboard side lined up fine. Didn't notice with the stock exhaust because of the long hoses.. now, looking at the transom it's noticeable....
