I'm not a big motor guy that's why I ask. It has 420hp that is supposedly "stroked to a 496 with big port heads" as the sellers mechanic told me. I know the boat as is should run low 60's but I want to get as much out of it as I can with not going to blowers or EFI motors. I know I can pick up a few MPH with bravo's and about 1-2 mph with sanding the last 6-8' with 180 grit but I didn't know like maybe swapping the intake or carb set up would do anything big and if so like what intake and carb. Etc

Motors are from an 89 cig

That would depend entirely on how many bucks you are ready to spend.
You need to know what internals you have in them before you formulate a plan to increase hp.
If you're not tready to spend 3k an engine minimum then its a waste of $$$

He picked up the 89 Cafe Racer with a 420/TRS package in it. There are posts on it in the Cig section

Make sure you throw all the trash, corn cobs, aluminum cans, and other items out of the boat. That ought to ensure you pick up a few MPH.

man, dont yall have jobs or something? you really have too much time on your hands...

and Griff, what about upgrading a carb/intake set up?
or what drive/ratio/props could i expect to pick up a few MPH from?

Griff was telling you straight when he said 3k a side for any noticeable gains. Gonna need another 20-30hp minimum for every MPH gained not going to get that on an intake swap.

Look who has to much time on their hands.

lol it was a boring friday night, too many beers with my buddies, who hasnt haha besides the point

you wont find much performance gains from drives or props without adding hp first. these are areas that are typically tuned to a specific engine. most bigger heavy V's run 1:50 drive ratios and thats most likely what you have. props, you have to play with but B1's are a good place to start unless you have an old school deeper X dim.
