Cobra Engine Swap in 03 Auto Mach!

[1979rs/z28]

Hey guys looking for some tips along the way here as I'm a ls guy and this is a totally new venture for me! My mach was pretty much a stock car with 150 shot, tune and H pipe till last week when a rod decided to propel thru the block! Car ran 11.50@117 on the old setup although. A good friend of mine (fomoco08) came to the rescue and sold me his 04 Engine from a wrecked cobra he had so here I am!

I know I have to extend some wires (iat, alt etc) and find a 8 bolt flexplate.
Plans for the new engine are just 2.76 pulley and the longtubes I had already on the car unless I have enough left over for the blower port. I need to work on the fuel system as now the car just has a aem 320lph drop in since I plan to spray it again with a little.

Always wanted a termi now I guess I'll be building one out of my mach :banana:
I'll keep updating this thread along the way. And again any tips are very appreciated!!!

Heres a few pics

The car

The break. Happened after a couple street battles with a TT300zx and Bolton LS3 vette

The drop!

The poor car. Thanks for its engine sacrifice though :beer:

Thanks man, been kind of tough finding info and getting help on this wouldn't think it would be with it being a mustang!
I'm kind of figuring things out on my own and I have a couple buddies helping since I haven't got much assistance online but will try to post all progress to hopefully help other.

I think you will be happy when it is all finished. I cannot wait to see how it runs with this swap in place.

Very interested in this as I have a yellow automatic o4 mach and I am in the process of putting together parts for a cobra motor

when I swapped a full cobra swap in I just used the Cobra ECU and Cobra harness. Used the fuse box from it too. buuuuut then I sold it after I swapped it in :lol1::lol1:

Good luck with it. def a fun project.

I would have used the cobra harness/ecu but in my case being a automatic it would be a lot simpler just extending my iat harness, map, and egr stuff. Im following all the eaton swap threads on auto mach's.

 

[stroked mach]

good looking start you have and with a small 100 shot on that setup it should be a good running car

 

[EVO-lution]

ahhhh okay...well regardless once it's done it'll be fun to drive around. I never got to drive my terminated mach around.

I used the flexplate from the Navigator. the transmission guy said the truck had 2 different flexplates but one fit my FTI converter and the 8 bolt crank.

Very interested I to have an auto Mach 1 and most of o4 cobra motor collecting parts at this point

Are you guys interested in selling the yellow mirrors off the cobra

 

[1979rs/z28]

Sorry for not following up lately guys! Weathers been tough on me in this area and from these pics you'll be able to tell I don't have a lot to work with!!! Got the engine in, need to do small things, route the harness some more, hook up exhaust and now swap out the blowers and after a tune it'll be running again. Heres some update pics ill get better ones tomorrow weather permitting!!!

Got a steggy stage 6 and some afs 18''s for it also today

What long tubes do you have everywhere I look I get mixed info on what fit the AUTO cars

 

[1979rs/z28]

They're Mac's they seem to fit fine. I had just put them on the old engine a week before it blew up!

have Kooks LTs and X pipe with borla stingers on my car lowered about 2 in they fit fine.

I was looking for a cheaper alternative then Kooks. I do have Kooks on my 6 speed ca tho.
