It’s been a few months since my last post.
You may recall I recently introduced you to my 1966 Jasper rebuilt 283ci with the GK 930 cam. Pistons are 0.040 with powerpack heads, cast iron intake and Rochester 2Jet carb. Looks stock. Runs great. Sounds great.
Up for comparison is engine #2.
Freshly rebuilt 1965 283ci with 0.060 hypereutectic pistons, powerpack heads, Comp Cams 268H flat tappet cam, cast iron intake and Rochester 2Jet carb. More details at the very bottom of this post.
Just broke in the engine on 4/16/22. A run stand is the way to go.
Here’s the video of the first break-in run.

After I adjusted the #7 exhaust valve, no more clickety-clack for video #2. More timing and carb adjustment is needed.

If you need a refresher, here is the Jasper 283.
