vin V and Vin H 4.6 motor differences... which is better or are they the same

[4drpower]

ok I have another question, are there any differences between the vin V 4.6 used in marauders mach 1's cobras (i think) etc than the vin H 4.6's motors used in aviators etc... please let me know all your info you have to spare and fill me in on this... any differences internally, is the block different? what..

I believe that the Aviator motors have a different calibration on their PCM's due to the fact of their smaller throttle bodies. The MM, and Mustangs use larger oval shapes TB's as opposed to the smaller 70mm round one on the aviator.

I don't believe there is a Mach1 cobra. There are Mach 1's and there are Cobra's of different varieties. The engines are different but the sizes are the same.

The Aviator uses a different set of cams than the Marauder. Or so I've read.

Pretty sure e wasn't saying there was a mach1 cobra, he just wasn't using commas in his sentence, otherwise he was asking about a marauder mach1 cobra.

Not quite.................

Marauders have a twin 57mm throttle body. Not oval.

There was a group buy on some twin 62mm throttle bodies for the MM awhile back.

You are correct, I was referring to their overall shape though,and the fact that they have higher flow rates. The intake tube on the cobras and marauders are an oval shape as well as the overall TB shape.

so if they are said to have different cams in the aviator, would it make a difference in the torque and hp since the aviator is also the exact 302hp and 318lbs ft of torque? im doing a swap in my MM because the motor is blown, and the owner of my work has a aviator 4.6 with 3k on it for 1500$ i know id have to change the upper and lower intake as the aviators lower is taller and the upper is opposite side TB, and the motor mounts of course along with the cooling fan mounted to the front and some minor other misc stuff like the oil filter and thermostat housing, swapping my headers, pulleys, and whatnot also didnt know if the harness was the same or not... help me out
