Thanks Vin. Ill be taking it to the track (port Mcneil) for the first time in june. I'm gona Buy the trans,clutch,scatter sheild,etc from my buddy that I described in an ealier post so I can run the car all out right out off the gate. I will let you guys know how it turns out MPH, ET, etc
Thank you guys for all your help through my first engine build. I have learned a ton from you guys.
Its much appreciated.

pro street,Im looking forward to see how your car performs.I know its been a while that we've been watching your posts.I wouldnt repair the car at the track,either do the upgrades before or fix later,why pay monet to work on their grass?
If you race it with the saginaw,try not to hammer the shifts and see what kind of MPH the car can achieve.Also,dont launch the car too hard,,,,
If you have traction problems,put a lower RPM chip in the MSD. I have a 6k chip in my MSD for street tire use. this helps lower the tire spin issue 2 ways
oh ya,,,have fun,,,

|vinniekq2||I agree that 670 may not be ideal.Does your MSD have a rev limiter?when that saginaw lets go you dont want engine splatter.If your engine idles well and the advance is quick,it might be close?|

More timing info here.

Not saying that anyone is right or wrong with their ignition timing suggestions, but maybe some of you would like input from professionals who have done their dyno time. This first chart lists crank timing suggestions for less than 220 degrees camshaft duration @0.050" tappet lift.
Demon Fuel Systems
Click on the tab titled "Performance Cam Profile" for camshaft durations from 220 to 240 @0.050".....
Click on the tab titled "Radical Cam Profile" for durations up to and over 260 @0.050"......

|RWENUTS||10 degrees more initial with 10 taken out of the mechanical will really wake up that combo!|

SBC Timing recomendations
Hey Guys. I just fired my motor today for the first time and was hoping to get some timing recomendations. Motor runs really well. Right know I have my initial set at about 12 degrees with the vacuum advance plugged. I'm all in at around 3000RPM at about 35 degrees. I think I could do with some more intial but I'm really not sure. See motor specs below and send some input my way.
If I have missed any info please let me know. Thanks in advance. (No pun inteded)
