Warm up to op temp, purge coolant system, check for leaks. Let cool, double check bolt torques on accessories, headers, intake manifold etc
then drive it. Tune it at the same time, do light throttle pulls to medium rpm and let engine brake. If tune is good, give it medium throttle to higher rpms and let it coast down, developing vacuum. All seem good then go wot full way through.

Re: 383 sbc best engine break in
Right. Rollers dont need special break in. You can free rev it some to see how the engine sounds and responds. Make sure timing is set and all cylinders are firing. Check for leaks etc. all the basics before taking out on the road and running it in. Engines need some load to break in properly. No need to baby them for hundreds or thousands of miles lol
