le1 le2 or lt-4 conversion

It's too bad really, Brett spends money on r/d and people spill his formulas out for free.
Did you happen to calculate the car's mpg? I wonder what the LE2 package would do to it gas mileage wise?

Alright, I have cast iron heads that came from my roadmaster engine that I am building up. Will Lloyd exept them or do I need to pay the core charge? And if I do need to pay the core charge how much will it be?
I'm looking at the LE1 package because of the cost. I want to make 400rwhp. Can I reach that goal with the LE1 package, all the bolt-on's and a really good tune(I'm going stand alone)?
Sorry for thread jacking
thanks
Edit: Also does his heads come with all new springs, valves, etc.
