I need help deciding which engine i should build, i have 2 454's an need to know which one is a better block, cast #14015445, or cast#361959 "p" can someone please help me out, thanks. logged boat #1: 1976 eliminator 18. Ok first of all my name is chris , i have build several engines before for the street but i have never built a boat engine . so with that being said i need some help some ppl are telling me that if i build my engine like i would for a street car it will blow up in a boat because its to tight . it will be going into a 21 foot schiada river cruiser v drive . so the motor i have is a 454 4 bolt. Mild 454 build for 454 blue boat just like many performance interested jet boat owners, he has upgraded, many components, over the past few years, reaching some impressive speeds. however, getting the engine to that point, decreases the reliability somewhat..
It was a .060 over mark4 454 with gm 990 heads (larger intake values and port work), and a tunnel ram with dual 660's. the cam was done by chris straub here on the forums (cstraub) and the engine ran hard.. We take a junkyard 454 shortblock, and without taking it apart bolt on a new top end and other parts to make 700 horsepower for less than 2500 dollars - super chevy magazine.
