now i know what mine sounds like from the outside.. always wondered..

@BlowingPumpkins 15mpg doesn't sound bad for the screwed up mixture. I though i would hear about 10mpg highway,lol.

Regarding y'alls mass airflow sensors... Mine is currently KILLING my engine! lol
Turns out that with heavily ported heads/intake, race valves, a big cam as well as a higher compression ratio.. a TON more air gets into the engine to be burned.. WHO KNEW!? hahah.. because of this my MAF is over compensating and dumping fuel in like theres not going to be a tomorrow, it's running super rich and needs a tune quite dearly. Just need the monies...

With the cam did you HAVE to get longer pushrods? New valve springs?

Yes and no. With the cam I chose (422) yes, 5.550" pushrods and dual valve springs. The 410 does not require either, but at the least you should put new valve springs in it.

Why?

Because it's original, very, VERY few people have built Ford 4.0 V6's like mine.
I refuse to be another built 5.0 / 347 stroker douche (absolutely no offense to those who have them).

Hey,nice truck,i came here cause of the Flowmaster video you have,your engine looks well built.
Just a question. Did you noticed any increase/decrease on MPG after the camming?

@truebassB
Because I don't have the motor tuned, I get about 15mpg highway with the MAF plugged in and screwed up air/fuel ratios, and I've seen 25mpg highway with the MAF un plugged and the computer running on a baseline preset A/F ratio.
