Hey guys! Still pllayin with set-up of the new motor. 292+0.040 w/ mild cam, 8.8-8.9:1 comp, cam installed @106, 2-brl Holley off '57 272



So on the carb there is a rod on the float bowl that when you open the throttle shuts an external opening into the float bowl? Anyone know the purpose of this?



As for timing has a couple year old cardone rebuilt unit with pertronix and mr gasket dist spring kit 925D.



Built for the street as a torque motor and driver



Checked balancer when i built motor TDC is true.



Right now set-up with 17 initial (ported vacuum) seems to like it snappy response in neutral and starts good with 17-18in vacuum. Can turn up to 20 initial and idle gets even smoother?



Limited internally for 38 mech advance. My search on here shows people saying anywhere from 32-38. Thats a big range. For a street driver any more on this? Not looking for peak hp more so mileage and roll on. Not sure on how the curve rpm is. Need another tach to watch under hood i guess.



Also my vacuum advance was peaking timing at like 60. Seemed like too much. I tapped dist. body to put screw in to limit plate swing. What should i be looking to limit it to? With a mity-vac all vacuum advance in about 10in vacuum.



I am a japanese motorcycle mech so timing is non-adj for us.



Thanks

Scott
