I actually was running a 750 holley and it was leaking a bit of gas..and I already had a 670 street aveneger sitting in my garage...so instead of fixing the 750, I just threw the 670 on it.

I am going to lower the overall timing to 35...but I am not comformtable with recurving a distributor other than changing the springs...the springs I have in there now give me 18 degress advance by 2500 so I would have to set the initial to 17 for now...

I have also never changed jets...I am pretty much self taught with all this stuff...so there is a lot that I am unsure of...
