msd streetfire ignition
I'd take a look at the odd similarities between the summit brand digital ignition box and the MSD 6AL... ;) ;) wink wink...lol .right down to the wiring diagram. the street msd box is for mild street apps only. for the price of the summit box and knowing you were getting a something very.... "similar" to a 6AL, i'd go with that. I've run them in multiple 600+ horse, 7000 RPM cars and been happy. Has a starter assist, a voltage/tach signal warning light. and it's completely plug and play, and makes the ignition completely independent to the vehicles factory wiring (dumping the OE ballost setup). that's my suggestion!
