I have a 353 fastech that had 540 lingenfelter engines and ran 90 mph max I just pulled the engines, installed Brad Smith 555's with 3.3litre whipples they made 830 ish hp im going with scx drives 1.34 ratio and a 34 pitch prop hoping for 100+ mph it handled fine at 90 so I don't see why 100+ would be a problem !

Right here Jake...been in a bubble since the blizzard...freakin sub-contractor issues, buying new trucks, billing...blahblahblah.... ANYWAYS, our 353 is 88-92MPH with 600ish HP per side, XR drives, Imco boxes and shorties...run both 4 and 5 blade tuned props...boat is stable. Wife happy at 85+MPH... Firm believer....".KISS" (keep it simple stupid) or pay big and be possibly miserable. Previous owner (AXAPOWELL) of my boat spent years of R&D getting this boat to where she is. We are doing a bunch of changes this winter but I assure you that we are not fooling with power or drives or props...if it ain't broke..... How fast do you have to go...

Cheers,

I've been having some silly ideas for my 500's

So what silly ideas did you come up with?

I'd highly recommend leaving the engines alone and spending the money on an ASD conversion. You'll spend more at first, but less in the end (unless you have a stack of drives laying around). With those drives you'll never worry about them and the boat will pickup about 10 mph! If you ever need even more speed, the drives are already done. To get 10mph with your bravos you'll spend roughly 1/2 what the ASDs cost anyway. The hull won't be a problem.

I don't agree with the last comment. Our fastech fell apart in the rough. Knew a couple others who cracked stringers. Formula makes a nice boat but they aren't bullet proof.

Every boat has a limit. Kinda vague here with "cracked stringers". Are you saying that the fiberglass "grid" broke?

Base of the stringer delaminated from the hull. Our 292 helm was seperating from the side of the hull. Not to mention our windshield was falling off near the rear bulk head.

Holy cow! Was it run real hard? I never heard of other 'birds with problems like that... :( Not saying it isn't so, just not real common.
