good job man! she sounds nice

[kingofnone]

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

[skateforlife150]

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

[BlowingPumpkins]

@skateforlife150

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?

[BlowingPumpkins]

@wootness3000

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?

[BlowingPumpkins]

@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.

[truebassB]

@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...

[bikr1975]

haha....mine sounds the same way if i disconnect the mass air flow connector.  blows lots of black smoke like a diesel too ;) but seriously, i only did it once.

[TheKing0fHalo]

Oh, cool. I got a 2000 XLT from my parents recently. Everything breaks lol. I've replaced the ball joints, control arms, I'm working on the mass air flow sensor right now, next is my front right bearing, it decided to go bad last week. Overall it's a good truck though. I'm looking to get some flowmasters though.

[TheKing0fHalo]

What's coming out of your exhaust, it doesn't look good. Also it sounds like it's misfiring.

[oddieboi]

@TheKing0fHalo Its water that's comming out of his exhaust pipe... It's condensation from the cold pipe meeting with the warm exhaust... and it was just Idling... not misfiring....

I can't wait to get a cam put into my 93 explorer(ohv)
