I 2nd the diesel oil suggestion, modern day motor oil does not have the stuff a flat tappet cam needs.
Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

X2 on the Bradd Penn & your next decision will be how often you'll change it. I would checkout www.bobistheoilguy.com Valvoline delo rotella diesel oil & others are good as is using GM EOS as an additive & might checkout hughes engines for his take on it

I used to run 20w-50 in my Hemi car. It had awesome oil pressure, but the downside was the time it took the pressure to rise when started cold. I didn't like that.....a good 5 seconds for the guage to reach 85#. So....to make the story short, the only vehicle out of the 5 I have that DOESN'T use 15W40 Rotella is my wifes 07 Charger 3.5 HO. Makes the trip to the parts store simple !!!

I'm assuming you're getting the multiple case discount
LOL ! .....buy it by the 19 litre pail.....60 bucks. One heck of a lot cheaper than individual jugs. I just usually stick some Comp #159 break-in stuff in with the oil when I service the race car.

I have been using 5W20Wt Valvoline non synthetic in all my Hi Po Mopar motors for a long time, the roller lifter motors get no additives, the flat lifter cam motors get a bottle of either zinc additive or Comp Cams lcam lube There have been horror storys posted on this site about deisel oil foaming, I have no expereince with that so I won't comment on it You need to think about what oil does for our motors, it needs to lubricate and cool That being said thinner oil moves quicker and with less resistance to the oil pump when cold, it also take less HP to turn the oil pump I've seen 10 HP loss at 130 F with straight 30 Wt oil years ago compared to the same oil and motor when we let the oil temps climb to 160 F No loss or gain of HP or torque when using 5W20Wt from 80F to 230 F I do run very loose oil clearances on the rod and main bearings also, .003 + on both I've shifted my 650 HP + pump gas street motor at or above 7000 RPM for a long time when running it at the track, a lot of laps over the years with no noticeable bearing wear or abuse OP, run what you feel comfortable with BTW, I do run both Rotella and Delo 400 in my CTD truck, depending on where and when I have the oil and filter changed and what they have in stock If you want to run race oil in your motor the only one I would run now is the RACING Pennzoil 25W50WT It has some lube additives, friction reduction, that no other oil has that I know of You can feel it when rubbing it between your fingers All the SCCA raers I know use it now

This topic comes up a lot.
I'm no expert but I'd recommend Rotella T or Delo 400 LE. Both have fairly high levels of zinc to protect a flat tappet cam and are easy to find and not expensive.
I run it, my dad runs it, many here run this diesel oil no problems.
I personally think race oil would be money out the window for your engine. It sounds fairly mild. Even fairly wild engines are getting by with cheap diesel oil.
Me too in a low deck stroker. Rotella T 15W40 gives me good oil pressure at hot idle and handles the moderately cool temps (mid 20's) I occasionally encounter in 3 season driving. I usually get it at Walmart.
