5.0 ignition system. which one???
ok guys so i'm all but ready to drop this engine in my F150 and start screwing up all my wiring b/c i'm still confused on the mass air system. BUT im trying not to think about that right now. the question at hand is whether i should stick with the stock ignition system OR if i should run MSD?? Do y'all think i would benefit from using an MSD distributor, coil, and everything?? if so which stuff should i get?? like the pro billet distributor, blaster coil or what. i saw they had a bunch of different distributors and boxes... is accel as good as MSD???
if you don't already know this is whats in the engine, 9.08:1 flat top pistons, GT40P heads, typhoon intake, B303 camshaft, forged 1.72 roller rockers, and probably going to use 24lb injectors for now. not sure which throttle body to go with yet b/c i don't know what i'm going to do with the mass air system yet.

The stock ignition system is all the motor really needs, it produces enough voltage to produce arcing between the wires if they are misrouted or degraded. But a higher output ignition won't hurt the motor so if you got some $$ burning a hole in your pocket....

You can't go wrong with MSD or Accel - they're both well versed and more capable than the stock ignition system. Yes, your stock ignition system will work, but aftermarket systems will work better. Both MSD and Accel's distributors and coils are high quality goods. Mallory makes some nice spark goodies too.
Going with an aftermarket ignition system gives you better adjustability over stock equipment, greater reliability (the Pro-Billet distrubutors are bulletproof if you ask me), and they claim to improve fuel economy with the multiple the spark systems. Get ready to spend some cash though.

I agree with Conanski, the factory ignition is going to sufficient for your proposed combination. I would suggest good quality replacement parts such as MSD cap/rotor and their replacement coil. Toss on a set of Ford Motorsport plug wires. Great combo for the money IMHO.

I used the stock dist. I put the box and coil on the same time the motor went in so i don't know how much difference it made ... Lew
