Projected hp. around 550 all motor also how important are the ohm values in wires should i get the least resistance wire available or is it not that big of a deal? any info wont be over looked and i will be very grateful thanks 5liter.

BUMP ALL THE WAY FOR MSD IGNITION

I strongly feel that MSD is the leader in Ignition technology. Amazing products, Phenomenal Tech Support, Extremely Durable Parts. Might come with a hefty price tag. But yet again Ignition is one of the key essentials for a great running car/streetcar/drag racer. Everyone around my town is running the MSD set up and im still encouraging all my friends to spend the extra money and buy MSD products. In my eyes Mallory is BULL$hit crap. They should of stuck with there marine line of products. Ive heard a few good things about ACCEL but I would buy MSD.
Hope that helped ya out. If you need some help with what to set up lemme kno.

MSD all the way. Ignition systems don't give you horsepower. What you need to look for in an ignition system is something that is reliable and will fire efficiently. I wouldn't go crazy with ignition parts either. Get what you need, don't buy a high dollar ignition with features you don't need that is going to cost you more money. If all you need is a good ignition with a rev limiter get a 6AL. The 8227 Blaster TFI coil is a direct replacement for the Ford coil. MSD also makes 351W TFI distributors for 87-93 EFI cars as well as 94-95 EFI cars.


Also I am curious if you bought the cam yet or if that is a list of parts you are planning on buying. That cam you listed is a bit small for that combination. It will work but you will be leaving alot of power behind with it.

thanks guys i think i know what im going to do now. and to darrell i do already have the cam though not installed i can send it back the reason i went with this cam is cause i am planning on running the factory eec with a custom tune and comp shows it as being computer controlled compatible, and it is going to be a street car, and i wanted to keep it a hyd. roller as well. However i am open to suggestions from a guru such as yourself. The afr 205 heads flow chart does not show any flow numbers past .600 inch lift but at .600 they spec 310 cfm i thought the cam would be good considering it gets close to that and because the flow numbers between .550 and .600 was only a difference of two cfm. So having said that lay some kowledge on me man, Thanks 5liter

You can give up running a factory computer. You might be able to get by with an SCT chip or something but you really need a piggyback like a PMS. Your combination is wild for a stock computer. You will probably experience flooding during cranking with injectors that big and a stock computer. I'd call Jay Allen and have him grind you a stick that fits your combination.

AFR 205 heads flow to .700 lift. They flow 310 intake and 233 exhaust at .700 lift. The lift isn't all to be concerned with. Cam timing, lobe separation and duration are factors as well.....probably more so than the valve lift itself.
