347 timing Vs 408 timing for a procharger im just curious about this as i've drove my car a little on 93 oct.
i see most of the guys are using around 18* timing on 93 oct .... but they are a 347 w/ d1sc a little over 620rwhp...
should i be able to run more timing with a 408 if using the same pulley (same cfm) and shift rpm or does the CI have nothing to do with it? im running a max of 23* but its around 3800ish rpms (not looking at the tune right now) and then dropping a degree every 200rpms up to where ill shift, around 6500 (well see when it goes to the track)
Thanks,
Tyler
