hey guys i know most will disaprove of this but i have a 6.1hemi and 5 speed auto probably goin in my mav it has 420hp stock and will get much better mpg than my 306 but at least its not a chevy motor
idk if a new hemi has been put in a mav im sure old hemis have if there has been a new hemi put in one i would love to see some pics heck id like to see pics of a old hemi in a mav
Thats a big motor and trans. I assume you have removed your shock towers? Not so sure the auto trans will fit the tunnel either.
I meant no disrespect by that post. I was amused by youre statement. Ive lived long enough to realize that its all been done before. The sages on this forum have done it all. If you want to put a hemi in your mav these are the people who can help you. Be forwarned most here wont like it.
More power to you, in more ways than one heck if a guy can put a Viper v10 in one then a Hemi should be a cinch. Keep us updated like it or not we still like to read about it :Handshake
I'm intrigued by the intention, but forced to inquire; why go through the pain of trying to adapt a completely different power plant/transmission when you can obtain the same hp from the actual manufacturer itself, using what it offers and has proven?
Ah it cant be any harder to put in there then the Caddy motor was to put in a maverick. He just had to cut the towers, make the exhaust manifolds, redo the front suspension with a mustang II kit, have a custom rear driveshaft made and redo the tunnel before it could even fit. Of course getting rid of the little 8" in the rear is going to have to be factored in because if you are doing that much work and putting that big of an engine in whey dont you upgrade the rear axle too. Of course thats just getting it in the car making it run is another story you need to make your own wiring harnesses to run both the fuel injection system and transmission, yes the transmission is controlled by the ECU. So if you are pulling the setup from a donor car you might want to gut all the wiring with the car. But that brings you to another can of worms dealing with the factory security system, from there you have to start adapting things like the steering column and everything to make the ECM work, or else you have to get your Eprom re-flashed to no longer search for the chip in the key. Or you could get a carburated manifold and bypass the fuel injection and all the advantages it might bring, like the fuel economy mode where it shuts off the engine cylinders as you are driveing but you will still have to buy an aftermarket controller to run the transmission....Arent new cars wonderful... The other option is to buy something like an AEM universal setup for the EFI but those are pretty pricey, usually in the several thousand dollar range for a universal setup and wiring. Or you can go with something like a megasquirt III you can either build it yourself and save you some money or you can buy one pre-assembled, you still have to figure it out and tune it yourself... but wait you still have to buy the transmission controller with either one of those options..... Of course running all the new fuel systems is a given so I wont go in depth on that...and we havent even started on the price of aftermarket guages that you would probably need to get everything to work. And as for better gas mileage Why dont you pass around what you are smoking it must be good stuff if you think those engines got good fuel economy... The 2010 model year was the last year Chrystler put the 6.1L and 5 speed auto option in their cars, heck it was the last year of the 6.1L and they got a whopping 13 mpg city and 19 mpg highway in the rear wheel drive Charger, heck even the 2010 6.1L in the challenger with a 6 speed manual only got 14 mpg city and 22 mpg highway...(if you dont believe me on the numbers here you go http://www.fueleconomy.gov/feg/bymake/Dodge2010.shtml) heck even the 8.4L V 10 viper engine gets better fuel economy then that setup, just barely better but it is better. Also remember it is a premium fuel engine only, they will tend to knock on mid grade or regular unleaded.:16suspect There are plenty of members on here getting 400 HP and similar fuel economy if not much better for allot less money into their 306, 331, whatever. Heck you could put a vortech supercharger on it with 8-10 psi of boost get 400+ horsepower on your engine and get a heck of allot better fuel economy. Ironically enough if you look at the fuel economy for the last couple years that the 5.0 was put in the mustang say 1992 the engine gets 16 mpg city and 23 mpg highway with a 4 speed AOD transmission.http://www.fueleconomy.gov/feg/noframes/8698.shtml
You've gone to lengths in making my point abundantly clear - I couldn't have said it more thoroughly myself...
I don't think gas milage is an issue at 500+ HP. no different than the...4.6s...that are "being" installed ...just another motor... being different isn't always hard...for everybody... ...any 500+ HP motor needs a car built around it... some people take a year or longer to install a 351 and most if not all of them are carbed... I say...go for it... ...back to making......with my carbed, factory EFI only engine...
