thanks for your answers

yes, I am under rules, I need to use carbs
6 days rally, 300 miles at day, reliable is the key, last year I use 2 engines,

I'm new to this engines

the original ignition needs injections signal ?

what parts and how many integrate the original ignition ?

what is the gm ignition ?, distributor, coil, module, harness, crank trigger, which car ?

If I need to build and adapt ignition, I believe m104 and edis will be better option. ?

do you know a place to buy this engines ? used low miles, rebuilt ?

thanks a lot for your answers
