I'm going with Hypertech's cap and rotor for my 305 TBI (p/n 4060), but I'm still torn between which coil to go with. Hypertech has a kit (p/n 4054) which contains the cap, rotor and coil producing 55K volts for $72. MSD has their Blaster GM coil (p/n 8226) producing 48K volts; which when combined with Hypertech's cap and rotor will cost me $61.

1.) Is 7K more volts worth $11?? (they claim as much as 5 hp)

2.) If I just go with Hypertech's kit, will I be able to hook up my 6A box with the same ease?? or is it not compatible?

 

i have msd 6a box...i use accel cap and rotor, accel coil, accel plugs, msd wires, hypertech chip(for now, once cam and heads go on a a custom fast chip will be in order)

 

if im not mistaken i had a to get an adapter plug from msd for my coil............call em when you get your coil theyll set ya up with what ya need
