Sorry this post is going to be a little long.

1970 Judge 3.90 gear, m21 close ratio, and 275/60 -15 tires

.060" over 400
Autotec 25cc dish pistons
RPM H-beam rods
Factory N 3.75" crank
"0" deck height
56cc Whitmore ported #614 RAIV heads - flow approximately 280cfm
Approximately 10.25:1 compression
Crane "041" copy cam installed 2 degrees advanced w/ Johnson R series lifters
Harland Sharp 1.65 rockers
Dave Bisschop ported Holley Street Dominator intake
OBX stainless Dougs copy headers
Luhn oil pump
Idle RPM 800 and 9.5" vacuum

Ignition:
MSD 8528 RTR distributor
MSD 6AL
Pertronix coil
AC Delco R43S plugs gapped at .050"
Taylor Spiro Pro wires

Initial timing is set at 18 degrees
Mechanical advance has the black 18 degree bushing installed and has one light silver and one light blue spring
Vacuum advance is hooked up to ported vacuum, and set to the maximum of 10 degrees

So it should have 36 degrees total all in by 2100ish RPM.

Motor runs strong from 3000 rpm up. I have the rev limiter set at 6700 rpm and it pulls hard right to it. I have not heard any detonation anyplace yet, but I've also been running a 50/50 mix of VP110 and 91 pump. The motor also starts great when warm, but starts a little hard cold (very cold blooded).

I'm going to be installing a Holley Sniper kit and would like to get this thing to run on 93 octane so I'm not killing the O2 sensors. I've been told it shouldn't be a problem by a few respected members.

I guess I'm just wondering if the pro's think I'm in the ballpark or not. I don't want to hammer this thing to death.

Thanks, Nate
