Hello all, I have a 1990 chaparrell 1900se 19' I/O 4.3l with the 2b carb, I have just purchaced vortec heads intake and 4b carb off of a 1999, sea ray for $500.00 , I am wanting advice if i should drop a hotter cam in there while i am at it, and if so whitch one? I am haveing the heads redone at a local machine shop, and can have the beehive springs installed at the same time, I am wondering if the extra $$$ for the beehives and cam are worth the extra? Shoot me your opinions, I am looking forward to the added power of the heads and 4b, right now with the prop I have i am only able to hit 4300 rpm, at wot, with a Power2 17p-23p two speed prop, I am hoping that the extra HP will be able to put me in the 4600-4800 rpm range and get a little better hole shot for pulling up skiers when the boat is loaded with 4-5 people. I scrapped the 5.7l swap until i try this first, I did buy the 5.7l merc vortec and outdrive, its sitting in my shop, awaiting results from the 4.3l upgrade. I may tackle this swap this winter but i didnt want the down time this summer. Thanks again Everyone!!!!
