331 bronco
im building a 331 stroker with summit headers with a old mustang block i have laying around with 4.10's and aussie lockers front and rear behind a five speed tranny. Will this combo be okay without a mass air conversion?

I think you'll be OK, it's gonna stretch the stock injectors for all they're worth and it may not have stock like manners at first, but the more you drive it the better it will get. An adjustable FPR would help stretch the capacity of the injectors some and combined with a wideband O2 sensor will allow you to dial in WOT.
