Hi guys need some help going to repower my 300 with more hp i want a cruising speed of 40 and top end of 50+ will the 383 350hp from mercruiser do it ??? with what props ?? any wot for the 6.2 ??? would i need 496 ??
sell the boat and buy what you want - this hull will never be a go fast - there may be a couple people on this board with the 6.2s, but I doubt they go anywhere close to 50+mph......forget about 8.1s the small blocks almost touch one another - you could add superchargers (powerdyne, paxton, etc) but you open a whole other can of worms with longevity, reliability, and fuel quality with the level of boost you would need.......did I mention just sell it and buy somthing that will do what you want it to right out of the box......
