Been really at the truck these past couple weeks and I have gotten alot done. Worked out all the bugs with the 460, switched out the u-joints and put on the correct yoke and also shortened my driveshaft, I put on a full exhaust system with cherry bombs, got the transmission working and put on a cooler with lines, installed seatbelts

, and i am working on the lights right now. Here are some updated pics.

I also just put a oil pressure gauge on my 460 and so far I am worried about the engine. On first start up I get around 40 psi of oil pressure. I let it run and it slowly goes down until it gets to around 5 psi. I was hoping somebody could help me with this.

main bearings in my maverick made it start out at around 28 and end up around 3 by the time I got to work..

but I am sure there are other reasons...

man i am really hoping that is not it, but that is what i am thinking it might be. The oil becomes a problem when it gets warm but cold its fine. I am hoping i don't have to pull the engine and have to tear through it to fix the problem. Well if anyone has any ideas on this I would like to hear them. thanks

Hurk, read this thread on similar oil pressure issue

What is your confidence in the gauge?
Start with an oil change some oil brands break down a lot faster than they should and the viscosity drops way off. If the engine has run hot a few times this can definitely be the problem.

hey thanks for the replies. I just changed the oil it was a shell brand 10w-40 oil i put in just last week. I don't know if it was any good but it was on the sale rack so i put it in there for now. I will change it again soon and probably try a 20w-50. When i put the 460 in the truck i converted the oil pan sump which called for a new oil pump and pickup, so that can't be it. I just bought the oil pump gauge too from autozone, one of those sunpro gauges. It looks right because once you start there is a steady stream of oil flowing to it then once it warms up you can see air pockets in it and not a good stream of oil going to it.

Try using Valvoline oil. I have found that it maintains pressure REAL well.

I just hooked up my tach today and let the truck get warm again and see what the pressure was. I know there is a 10psi per 1000 rpm rule and once my truck got warm it was right at that. I held it at 1000 rpm and it was at 10psi then went to 1500 and went to 15 psi then went to 2000 rpm and went to 20 psi. I don't know if this is good or not but it seems kinda low. Thanks for the info so far.
