Cool start, nice to have another 63 added to the pile. Is there a harmonic balancer bolt on the 283 or is it press on? All early ones were press fit iirc, I had a nasty 283 in my 57 for a while, and we had to tap the crank snout for a bolt, it would work off at extremely high RPM's. Great engine for sure!
