Granted this is going in an old bronco, but it runs mustang electronics.

It is a mild cam naturally aspirated 393 stroker (approx 9.7:1 compression).. RPM heads P&P, Lightning lower, Explorer upper.. doesnt see RPMs much past 5500 .. 90% of the time under 4k.

I need some suggestions on the MAF/TB sizes as well as injectors.

I dont understand why you would have a MAF substantially bigger than your TB.. so unless you guys convince me otherwise, I would like to keep them fairly matched..

I had been thinking about 30#s w/75mm ... but some reading on various forums has me thinking 42#s w/90mm... I will be porting the upper, but opening it to 90mm seems like I am asking a lot of the stock casting.

Ok.. so lets hear your thoughts!

Thanks in advance.
