Timing for new TFI 355ci.
I finally got the new motor in and running. It is using Trick Flow 420hp. Street Bracket kit w/stock TPI., Sanderson shorty headers. The cam is flat tappet hydraulic 228º/234º duration at .050. Heads are 64cc. chambers 195cc. intake..
I just put the stock chip back in for the break in, was running real rich w the custom racing prom.The timing is currently set at 10º advance. But still seems to be running to rich. There are some white puffs of fuel, and the exhaust tips are black. Seems to me it could be advanced much more. Any ideas? There is about 1K. mi. on it now.. Thanks in advance, Chris
