Folks,

I built a 68 400 engine to HO specs several years ago and broke it in on my engine test stand, but never installed it. It ran very well. At the time, I had a Melling M-54D and M-54F oil pump (both new) sitting around. I installed the M-54D because I didn't want to have issues in the future with blowing seals. Now as I look back, I question that. I'm pretty sure the M-54D has a max pressure of 60PSI while the M-54F maxes out at 80PSI. The engine is for my 68 bird convert and it will never be run very hard. Which pump would you use? At the moment, the engine is sitting on a standard rotary engine stand and it would be easy to swap out the oil pump for the M-54F if is the better choice.

BTW, do any of you have a recommendation for a cheap oil priming tool? I loaned mine out and never got it back. I see lots of cheapo ones online with lots of complaints.

Thanks
Old Joe
