I got the boat from a guy who got serval estimates for over 30k to re power the boat. It's has no gimbal no out drives no nothing the boat was a theft recovery. Would it be too hard to go triples sbc. The only reason I want the sbc because the motors are complete marine engines (trading a street bike for the engines ). So if I can built one engine and find 3 bravo 1 ??????

first, no one wants small block in a boat this size

second, no one wants triple engines anymore, even if they are small blocks.

so if you go twin small block, you get market value minus quite a lot on resale.

if you go triple small blocks, you get market value minus.... Can't figure out... bare hull value is what you are gonna get back...

Never going to be the holeshot king , but you can almost buy a spare alpha 1 g1 for the price of taking your girl out for dinner .but if you ever want to go big , ill bet whatever you paid for the hull and free motors , just doubled .

sell the small blocks and buy BBC, the boat needs BBC balance and TQ, don;t destroy a good hull and waste it....

I would put a pair of 8.3L whipples on those 383's and 6 blade herrings. The alphas should hold up fine, just run that neo oil in them and a drive shower.

I say buy it put those motors in it and go boating & put a smile on your face. Figure out what you think you need/want for the next year and start stock piling your parts. Do it and report back, what the heck is it going to hurt?

You can't fit a midget in the bilge to winterize a bbc 353, no way you'd ever put triple sbc's in it without cutting up the cockpit. Sell your street bike, buy a pair of 454 mags and bravos.

My buddy's 300lbs does everything in his 353 no problem, I tell him he looks like a wedged sausage though! E
