400 SBC Timing Specs
406, flat tops, bottom end stock otherwise, mild cam, 487x heads, performer intake holley 750 vac sec., 4 spd. msd hei stock config., what would you guys recommend my total timing to be set at? i was thinking somewhere in the 32 to 34? what rpm would i bring it in at 2500 to 3000? i dropped my dist in, fired right up ran smooth with a 600 holley, havnt pulled timing yet, just drove it to see how it did, had a popping in mid throttle, left as i reached redline, thought it was lack of fuel, swapped to 750 still pops a little, so im going to try to dial timing in and go from there. any other ideas?
