yes, that's a ported cylinder, done by Riva about 15 years ago. Since there is no 5mm engraved, it seems to be for stock stroke. It was undoubtedly ported for racing

Thank you! The guy I got it from said it was an old race motor and it was pretty quick.
Any idea what the - 480 and MCB on the side means?

I recently picked up a motor that had similar engravings although mine had a 6m6 crank. Did you ever run yours? What set up are you using? Pipe, carbs, etc?

What carb set up?
And I'm not even gonna ask about exhaust because I know b pipe will be only answer...lol
You can run stock 38s all the way up to a/m 48s. Race port timing and larger carbs will accelerate well but it may not hop out of the water quite like a stock motor with a pipe or a freestyle ported motor. Just my experience/imagination on my superjet. I have run a stock motor all stock for years then put a bpipe mod on about 3 years ago, then ran a different engine ported race port timing case62t/61xcyl on stock 38s running 210 psi, and now the same ported motor all freshen up with old school novi 48s and vf2 reeds. All were run with stock pump and a hooker 9/15. Msd enhancer or a total loss are a must.
Has to do with inlet velocity and what not. The smaller carbs tend to have a stronger induction signal than oversize carbs on a 81-83mm engine. Good for hitting wakes. The larger carbs tend to pull more mph and acceleration.
