HOLY CRAP!!! only 2 hours on engine,spun bearing!! long
Man I don't eve know where to start!!! We put together a Ford powered air boat These boats mostley have small chevy's or Cadillacs for car engines and rarely have Ford's in them. We wanted to put a Ford in this one "cause we is Ford peoples". This has not been easy, or fun!
The first motor was a 460 with iron heads, decent cam, good headers,intake and carb. This engine ran great, just a little on the heavy side. The first upgrade was TFS streets. The first problem was they were ordered with solid roller springs by accident (my fault, clicked wrong head an Summit.com). Took heads off to change springs and decided to put a stroker crank in it while it was off the boat. This engine ran great for about 40 hours, rarily seeing 4000 rpms and then the altinater bolt vibrates out, water pump belt falls off, engine burns up, melts a couple of pistons, warps heads, etc. etc.
Engine #2 complete 514 short block same cam, (wasn't hurt) new roller lifters, new rocker arms, heads milled and checked, 9 qut. pan and pick-up. another 40 hours or so and it spins 4,5,6,7,8 mains and rods. obviously an oil starvation problem, but why? check out oil gallys for and pump for problems nothing stands out except the oil pressure never got over 50#'s not even cold.
Engine #3. Use the 68 block from engine 1, all new internals, nothing is carried over from old engine except oil pan, and heads. Had 2 hours on it,.....yes 2 hours, and the same thing happened!!! WHAT THE HECK IS CAUSING THIS!?!?! Could it be the pickup to close to the bottom of the pan? This engine rarely see's 4000 rpms We are tearing this motor down this weekend (hopefully), the first thing we'll loof at is the pickup -to-pan distance. Is there anything else to look for??? Please help, any info is appreciated.......Wade
