Hi Cyber Mopar Fans,
Well...I am about to take the plunge into the world of Modern Hemi in a classic ebody.
I have a restored and stock 1970 Barracuda convertible and I am going to transplant a modern 6.4 Hemi with a NAG1 transmission. My goal is to use 100 percent stock modern Hemi engine and transmission components (no aftermarket hot rod changes) and to drive the car as a cruiser.
I want to keep the exterior appearance of the car stock and I am aware of the need to modify the following components:
Naturally some advice from guys who have done this swap would be helpful.
I am either:
1). Buy a low mileage engine and transmission with the various modules and the shifter as a package.
OR
2). Buy a new MP 6.4L Hemi production engine and then buy a low mileage NAG1 transmission and the modules and shifter as separate units.
I am leaning toward option 2. Yes it is more of a pain in the butt to find those parts however those transmissions are very easy and cheap to find because nobody is using them as swaps and the same goes for the modules.
Has anyone gone either route and would like to give advice and or send some photos or link to build blog?
Does anyone have any of these parts available for sale?
What year transmission and parts should I pick?
What vendor do you recommend I use for the engine/trans harness?
What vendors should I stay away from (offline comments are preferred)?
Here is the stuff I am aware of…
Shifter:
Naturally the shifter will need to be adapted to the existing automatic center console (the 1970 OEM console will need to be elevated to accommodate the increased height of the modern shifter and cut open to accommodate the width of the modern shifter OR I can delete the console completely and just have carpet)
Transmission:
The OEM trans cross member support will need to be redesigned to accommodate the girth of the NAG1 and the lower support fabricated. Trans cooling lines will need to be plumber as well.
Drive shaft:
Drive shaft will need to be altered.
Fuel system:
A in tank high pressure fuel pump will need to be installed and a new fuel line installed. I hear guys are running the 99 Corvete fuel filter/regulator and then running a single fuel line to the engine compartment.
Engine compartment:
Radiator and cooling system hoses. Engine mount. K Frame will need to be modified to accommodate the oil filter. My hope is to cut out a chunk of the K Frame where the conflict is with the oil filter and then fabricate a stiffener as needed. This will only work IF the suspension parts do not attach where I need to cut out parts.
Gas pedal:
Gas pedal will need to be converted to the electronic unit.
Speedometer:
Speedometer will need to be GPS sensed with an electronic servo motor OR the mechanical workings replaced with calibrated needle drive. What is the best route? My guess is the speedo mechanism removed and replaced with new. What vendors can do this?
More stuff I cannot think of right now
