I've got 2826 miles on my 416 stroker. Comp XE274-solid. Using the standard Comp solid lifters. No Issues. Edelbrock heads have standard Edelbrock valve springs. I have the Comp Magnum roller rocker that come bronze bushed.

Broke in motor using the Comp cam lube. Never used it since. 1st two oil changes used 15-w40 Rotella and Justice Brothers Engine Treatment (ET/33P) to replace the Zinc. Had plenty of oil pressure and that 15-w40 is sort of noisy so I now run Castrol GTX 10-w30 from Walmart, again with JB Engine Treatment (ET/33P).

No issues.

I've run the car at two all day road course track events, one autocross, and cruise RPM between 3600-3800. Car will see high rpm down long straight all the way to 6,000 rpm.

I took the car tonight to the grocery store 4 miles and back. Shifted at 5,000 only once . It's my only running car I own (have another vehicle provided by/for work). So it gets short trips also.
