i recently purchased a 74' 260z with a built L28 swapped in from justazcarguy. problem here is my ignition system. it has an E.I. from mallory, but engine "stumbles" through the RPM band (doesnt matter if its high or low rpm's) the motor is built like i said: silver dllar pistons,P&P n42 head, 6-2-1 header&exhaust,schneider aggressive camshaft,10 or 11:1 comp ( i cant remember), DUAL point mallory dizzy, and last but not least triple 44mm mikkies! so should i "rebuild" the mallory dizzy or swap to a 280zx dizzy ???hmmm... i wonder whats easier? the mallory also has an aftermarket ignition box. and i heard the black box dizzy wont take to the mallory ignition box. help at this point would be nice. :stupid:
