What should the all in timing be on a SB350 and at what RPM? Is it Cam and Combo Dependent?
I have the following combo:
MSD HEI Stock Style Distributor
Stock 1.94 heads
Eddybrick Performer Intake
1 5/8" full length Dynomax headers
Holley 670cfm Street avenger carb (properly tuned)
Unknown mild street cam
stock 2-bolt bottom end
Well built TH350 w/2600-2800 stall converter
12 bolt rear w/3:73 and locker
Yada, Yada, Yada
I know some of the specs are moot for setting the timing, but I layed it all out on the table just in case it helps.
I have set the initial timing @8 degrees BTDC (vacuum disconnected) as a start. After setting this I checked the timing and it is all in @24 degrees BTDC by 2400 RPM.
Am I way off or is this close to where I should be. I have a weight and spring kit to change the curve of the Distributor and the vacuum canister on the distributor can be adjusted to change the vac advance.
I thought I should be closer to 34-36 degrees all in? Where should I be with this Mini Mouser?
Thanks for any help.
