Hurst, the low RPM bucking especially concerns me. This car will be a daily driver - whenever I'm not on the bike I'll be going to work on it, that means stop n go traffic. I'll be going on interstates with it, that means long periods of 2,000-2,500 RPM driving.
I think the low RPM bucking I experienced had more to do with the cam than anything else. I would just drop a gear to keep the RPM's up and it was happy. Not exactly a DD friendly experience for sure.
I think you could change to a more street friendly intake like a Street Heat or System Max it might work better than with that particular intake. And go with a milder cam,.. say something like a Comp XE270HR, XE268HR or even a E-303. Before I converted to carb I had the Edelbrock Victor 5.0 intake with the AFR 185 heads and it was an absolute turd below 4000 RPM and experienced most of the bucked with this intake. After converting to carb using a Vic jr intake and 600cfm Holley,.. the bucking decreased but it was still there.
In my case I just wanted a track car. I didnt car about street manners. The way it was explained to me was that with a motor that small the 185cc head and a large intake like a Victor or similar,.. they dont produce the port velocity to make the HP except at high RPM.. and then it comes on with a surge of power. Kinda like if you've ever driven a 96 - 98 4V Cobra,.. how after the IMRC's open up after 3500 RPM and the surge you get from 5000 - 7000 RPM. The combo your running if you ever sprayed it or put a turbo to it.. then it would probably be a really sick combo especially at higher RPM's.
