Hi,
You NEED to 'O' ring the heads for blown 302 engines, use head studs instead of head bolts also.Fel pro makes an O ring head gasket that fits the tfs grooved heads.
The factory Ford tfi dist is best with the factory EFI, if you go with another system a duraspark dist will trigger it fine.
Msd makes a 6 BTM ignition box that retards timing as boost increases. Also you need a Vortec or Paxton FMU fuel regulator that increases fuel pressure as boost rises.
You only need 1 EFI fuel pump, has to be big enough to support your boost level, say 255 L/hr for up to 15 PSI.
I ran 8 psi boost and knocked 2 seconds off my 1/4 mile time, but the car overpowered the traction and would go sideways at 100 mph. Spend $$ on good suspension , a rollcage and tires.
Good Luck,
Perry.
