Re: I am wanting opinions about buying a Motor
You know what.. I read on here that some of you have 350 engines that run at 80 lbs preasure and it is seems ok for the motor to do that .. I could with (( help)) change out the spring to a different one and get a lower PSI ,, as for changing out the motor ,,I would need lots of help and after reading and looking at summit and others , ,the motor would run me 5 plus thousand dollars plus Tax which is 6% guessing the cost would be over 7 k
I think i need to fix what I have as I did not know the cost of new , thanks again for the help ,,I am backing off a new motor as my truck is not worth it and my age tells me to not do so.. hope you understand my thoughts on this and did not want you all to think I was dead set on a new motor..

Re: I am wanting opinions about buying a Motor
I re-read through the posts. It seems your concerns are metal flakes in the oil filter and high oil pressure. I would recommend taking an oil sample to a heavy equipment dealer near you (call first). Most can do an oil analysis and give you a good idea of the condition of your engine.
Secondly, how confident are you that your oil pressure gauge is accurate? I would use an oil pressure test kit to verify your pressure before you make any changes. They're cheap on Amazon, or you might be able to get a loaner at an auto parts store. If the oil analysis is good and the pressure really is high, you can just replace the oil pump with a standard displacement unit. I like Melling, but there are other good ones, too.

Re: I am wanting opinions about buying a Motor
Larry, I got your PM. I can probably help you. Before committing to changing out anything, do as the others have suggested and have the oil analyzed. I'd as change the oil in the engine, again if you already have done it, and cut the oil filter apart. Look through the pleats in the filter and see if it has any metal shards or flakes in it.

Re: I am wanting opinions about buying a Motor
I have found a machanic that builds race car motors to help me find out about the small metal flakes in my engine ,,He is going to run a camera down inside the motor and see what it looks like for flakes .. then he is going to check my oil pressure guage out to see if it is accurate ..then after that I can make my mind up with what next I want to do .
Where can I find a new Oil Pressure guage to fit in my dash for this 83 Chevy truck ? If I need it ?

Re: I am wanting opinions about buying a Motor
Hope it turns out well. When you describe the flakes as small are they larger than 1/32" or more like metallic paint? If the short block checks out maybe swapping a set Vortex heads would be a good option to get the power you want and stay under budget.

Re: I am wanting opinions about buying a Motor
I’ve always gone with the 10% ratio if the lowest and highest are in that range I leave it alone . Did they do a leak down test
