have been looking at the 350HO... I think if I was going to do it, I would only use GM
Well...... Let me tell you a little story about my GM Crate 454HO......
I have told this before on other threads as well...
I purchased a new GM 454HO from my local chevy dealer....tossed it in the blazer,,, primed the oil pump and didn't really like the O/P I was seeing on the gauge... I tried a second gauge, and got the same result...
I called chevy's tech support line... spoke to a tech and he said...and I quote..."there is no way your 1/2 inch electric drill is going to spin the oil pump fast enough to make any more oil pressure.... crank it up... it has a warranty anyway.."
hmmmmmmm..... not the answer I was looking for...
buttoned up the rest of the engine...and cranked it up... the oil pressure went from 50 psi to 0 in about 5 seconds...
I shut it off...double checked everything and cranked it a second time....
50 to 0 psi in about 5 seconds again...
I called them back, and was told.... you must have done something wrong....
At this point I had convinced myself that the oil pump shaft was slipping or the pickup was loose or something to that effect, and decided to pull the pan before I pulled the engine back out.
I dropped the pan down,,,but had to remove the oil pump before I could get it to clear the crossmember....as I was loosening the oil pump ( working from within the pan still ) My wrench slipped out of my hand and fell into the bottom of the oil pan...I reached into the pan to get the wrench.....
and came out with a handfull of plastic wrap.....
once I got the pan dropped...I found several pieces of plastic wrap and 2 pieces of 6"x6" cardboard sheets laying in the sump....this is what was getting sucked up against the oil pickup screen when I cranked the engine..
I threw the pan and all the junk in it in my truck and drove straight to the dealer where I picked up the engine....chevy and I had a long discussion about the details and they ended up giving me a written warranty for 2 years on the bottom end...
I put it all back together,, and never had a minutes trouble out of it since...
