RPM Airgap vs. non-Airgap?
I cant speak about the gas down there wich is obviously the critical point but with that cams duration and 110 lobe sepearation you will bleed off some cranking compression,that coupled with proper ingintion timing and you may be fine.My friends and I all run 10.1 enignes here on 92 octane with no problems-actually my brother gets away with 11.1 but he brings the initial timing back to 12 on the crank and then mixes a little race gas for events.I recurve my own distributors and its a pretty simple deal once you do it.I always shoot for 32-36 total with 14-16 at the crank and usually 20 in the distributor.I havent had a performance car yet that didnt like a similar ignition curve and 14-16 crank degrees of timing.If you check your cranking compression there is a basic ideaology from alot of knowlegable builders about the p.s.i. and how tolerable the enigne will be to pump gas,I wont really run over 180 max with a proper tune/carb but Ive known some who push it a touch over.Also if possible pull a head and check your heads cc,gasket compressed thickness and piston type/deck heigth to get a acuurate rating of compression.
