383 Stroker 410 h.p 1996 - 2011 8 or 12 Bolt Intake Manifold
$3,295
383 stroker is made from two engines, the Chevy 350 and Chevy 400 engine. From the 400 Chevy we use the crankshaft however our 400 crankshafts are new. The 400 crankshaft is fitted into the Chevy 350 making a longer stroke
350 rods are used with special designed pistons. The cylinder heads, camshafts, timing gears and valves are all from the Chevy 350 engine. The Chevy 383 stroker makes more horse power but what most do not know the 383 stroker has much more torque.
Torque is what you need to move heavy loads like boats. Think of torque and horsepower this way. Big diesel trucks have 300 to 400 horsepower, but what moves them down the highway is their torgue 1,200 or more.
We have installed Chevy 383 strokers in customers boats and gained 15 miles per hour however you must change your prop to gain 15 MPH or you can have massive torque power up to 5,200 RPMS. Not changing your prop makes your boat great for pulling skiers and tubers. If you have 383 stroker marine questions just call we will be pleased to help

Yes you need a tune that is not a merc engine and if you go there you will need to get the cam card actually all of the major details... so obd can tune the engine..They cannot guess
Id bet your in a pickle here... that is no one to custom tune a merc 555 system. You can still do this though... replace the 555 with a mefi 4b harness and ecm about 700.> your mech owes you one for having a new block flashed for a merc engine they are not even close. Opps and obd can tune that 383 with a mefi ecm
