1994 engine ?????

[semiwrecker1]

I am in need of a new engine. The one that I have right now has oil pressure issues. when I start it I have great oil pressure both on the dash and an aftermarket guage but after warm up it drops to 5-10psi. so my question is...I have another block that has been punched out .040 that needs a rebuild. do I have that one rebuilt? or do I just buy a fully remaned? and if I buy a remaned how big can I go? if I have the other block done what can I have done to it so I can still use the factory pcm ect...sorry if this has been discussed before


right now I dont do any heavy towing but i do plan on buying a 20-28ft pull behind in the next few years

Is your oil pressure at 5-10 at idle or when running at speed?
If at idle, that is pretty normal on a higher mileage engine...it may be just fine. Maybe try a 10w-30 instead of 5w-30
