hey,

I am cosidering in a while from now, to do a 4.6L DOHC swap in a 1999 and newer ranger, and i know that the mach 1 has 3 more hp than the aviator, but is there any difference in the engine internals that one should know about that can help performace?

thnkz,

DRFTNGKNG!! :P

good luck getting the 4.6 to fit, it's a wide SOB. only trucks i've seen had them crammed in there were 97 and older.

yea??

because they did a project on this on trucks on spike tv. i thought that it would be a better build because of the A- link suspension instead of the I- beam suspension and also the rack'n'pinion steering.

The one on spike they modified the frame of the truck heavily to get that 4.6 into that Mazda, so unless you want to strip the truck down to the frame, a 302 would be your best bet. Also the Mach 1 Engine does not have forged internals where as the Aviators are forged i believe. And BTW, my buddy has an 04 Azure Blue Mach 1 and man does that thing light em' up even at 305 horse

they are the exact same the mustang makes more power due to a more agressive tune on it

huh.. yea however, the 5L everyone does that. plus the dohc 4.6L is a lot lighter and creates more power than a 5L. so its a win, win situation. on spike they were putting the truck as a track vehicle so it had to be sturdy, but for cruising, it should be fine.

you still going to have to modifiy the hell out of the frount suspension to make a 4.6l fit in there

is it because its wider? arent the new a- arm suspensions in the 1999 and newer rangers make it better for an engine to drop in because its smaller and provides more space and cleareance in the engine bay? u c i still dont understand why a 302 can fit easily into an engine bay of a ranger, rather a new gen modular motor.

a 302 is a 60Degree v8 meaning each bank of 4 cylinders is 60 degreees apart whereas a 4.6l is a 90 degree v8 and it is much wider so it would hit the a-arms. dimension wise a 4.6l is bigger then a 460

look at that picture i posted. the 4.6 is like double the width of the 302. now go look at your stock engine bay, take some measurements. you can find dimensions of the engines online to help you make your decision. also, there are no headers pictured. there are headers specifically designed to drop a 302 into a ranger. there is no such system for the 4.6, so good luck first shoe horning the engine in there, then finding room for the exhaust.

exactly, Steve is dead on!..... but, If you have super deep pockets, go for it... it will def be a challenge,, and more than likely will lead to a dead end... these guys are only giving a fair warning

351 windsors are trouble some to fit in because there like 2" wider at the intake, that 4.6 is going to be hell to try and fit. I would go 302 also, you can build a 302 cheap since parts are everywhere

apparentlyy he says that its an easy install. idk but hes prob joking. :P

did you not see this picture i posted?

1) how heavy is a 5.0L (302) -500 lbs? iron block and heads?
2) would a 4.6L 3V or a coyote motor (5.0) b better?
