Question on lifter retainer

When my engine went out on me 3 months ago, I pulled it out and the original owner before me made good (as it only had 1600 miles from a previous rebuild). When I got the engine back from him, it was missing a few pieces, such as the lifter retainer and bolts. I get a used one from jwaller (along with some other stuff that is missing). Well, when I go to install it, I was expecting to see this type of retainer

Well, the bolt holes where in the wrong place. I had to go and get a plastic piece that went from the front of the engine to the back of the engine. One for each side. I am starting to get a little scared, as I know now this is not the engine I sent him. He said that machine shop replaced only a piston and rod, as #5 got starved. What year motors used the plastic long type of lifter retainer?

the plastic reatiners are not a bad thing. they came in around 94ish..about the same time as balance shafts....but just before hand. you will wanna check bc I doubt seriously that it has the right main caps.....

I didn't check the main caps, and I can't unless I pull the motor again. It is in and ready to be fired any day now. I just found that picture on techweasels page and that reminded me how that was different from what I originally had. The motor I gave the guy was about to have the 4th rebuild on it. Maybe something was wrong with the block and that is why the went with this one. I am crossing my fingers that they still used all the other parts from the original engine except the bad piston and rod.

Is there a way to find the compression ratio with the engine in the truck? Can I do a compression test and then use what I get in a math equation to find it? Something in me tells me it might not be the 8.x.

Say it has 8.5 compression. you should be right around 110lbs. If your cam is stock and the barometric Pressure is 29.92 (in mercury). Should be close enough to give you a Idea. Here is a site with a bunch of calculators.

Thanks Bob. I am going to run a compression test on it Saturday when I fire it up.
