Sorry for all the questions,just don't know much about Sonics. what would i gain from a 28 with twin small blocks over a single 502.

HOPEFULLY SPEED , HANDELING , AND IF ONE BREAK'S OUT ON THE WATER YOU CAN STILL GET HOME WITH ONE MOTOR

I was thinking that a single 502 would run 60 and a twin 350 would run maybe 66. Am i way of on this?

You would learn many new swear words when you work on the twins but I think they are worth it.

THATS KIND OF WHY I WAS THINKING SINGLE AND SLAP A WHIPPLE OR PROCHARGER ON IT. i AM IN NO MEANS A SMALL GUY I MAY BE SHORT BUT THATS ABOUT IT.

With the size of the boat, twin small blocks is the way to go. Lighter than big blocks and two screws over a single engine setup. Tied up with one at Raystown lake and he stroked the 350's and says it's running awesome.... don't have any real numbers for WOT.

Single 502 boat on a good day = 60mph
(2) 350Mag/MPI/Bravo = 65-68mph(best pkg.)
(2) 6.2MX = 67-70mph (Lots more $ per performance)
They made some w/ T-BB's...faster, but tougher to drive because of heavy stern.

im looking at 3 right now one with 350's one with 454's(already ruled that out) and one with a single 502. I like the 350's but it has alpha's and i would like to stroke or whipple the engines soon after. I am kind of leaning to the single 502 and a blower. Im not really looking to go much faster than 70,anything over is ok but as long as i can run say 60 in some chop i'll be happy
