Once I'm done on the dyno, then what? My choices are: Try to find some Valvoline VR1 SAE30 (since they don't have a 10W40, and 20W50 is a bit too thick) Go to a Brad Penn 10W40 Semi Synthetic Or a full blown synthetic 10W40 Amsoil Even though it's a roller cam engine, I think the zinc would benefit in other areas. I guess my question is, would the rings be sufficiently seated after the dyno session to go to a synthetic oil?

The rings should be seated in a short period of time so that would allow you to run what ever you want. I blend a couple of oils(thick and thinner) to get the pressure I want after a pass when its hot

I like to change the filter after the first 10 passes or so too. I ran VR1 20/50 in mine this weekend for the first time out and I will switch to Brad Penn which is only partial synthetic in a few weeks. 67 Barracuda street/bracket car 11.27-119 68 Dart 502 BB 8.70s-152 414 cid SB Dragster 7.65-174
