OK, I've got a 4100 from Pony Carbs 1.08 bore on a 1985 302 block. .030 over, balanced and decked for ~ 9.3 :1 compr. ratio. The cam is flat tap hydraulic 216 Adv. Duration @ .050... (pretty mild / decent idle) and World Products Windsor Jr. heads, and Edel. Performer RPM intake.... when I give it full throttle, it nearly sends me first through the windshield, then it snaps me back a half second later when the motor gets its act together and it pulls awesome! I'm wondering if this is the carb's power valve / accelerator pump issue or is this a timing / spark curve issue? If I feed the fuel to it rather than stomp it, it works great through a solid power band. Per Jon @ Pony, I've got the timing running max vacuum, so what's my next move? I want to install an MSD distributor (presently running Pertronix in an orig. 289 distributor), but I want to close one chapter before introducing another variable. Thoughts?
