LSx 1967 Mustang

Thanks , it's approx. 7 1/2" on the Cougar bezel so I'm sure the Mustang is the same . The Cougar bezel only has locations for the speedo , tach and one small area between the two . Thanks again .

i measured the aluminum gauge support so it is most likely has a larger opening than the plastic bezel. i think with a little cutting you could possibly use it on the cougar dash.

I decided to go cheap and mod my gas tank myself. I went to a local pick a part and got a 2000 mustang gas tank for $20. I cut the fuel pump ring off the top and drilled the fuel pump basket spot welds out. I bought a 98 cobra fuel pump module (has 3/8 feed, 5/16 return) with a walbro 255 pump installed. all in all i have in tank efi for under $200.









the mustang fuel pump module is pretty unique, the pump assembly snaps into the welded basket and the hat is separate and connected by the feed hoses. The 98 mustang gt and cobra were the only year that used this basket setup with a feed and a return line in the hat, the previous years used the pump on a stick setup like a fox body. all years above 98 used a pwm fuel pump with only a single feed line.



running a vette filter regulator



also picked up a Holley HP LS1 kit.

I ditched the GTO pan and went with a canton front sump. Gives loads of room for the factory cross brace and steering. Im going with manual for now, but power will be an easy upgrade.





ditched the power steering pump and re located the idler pulley. easy swap back to power if needed.

That alternator may hit the fender. I have the Holley alternator bracket and it's very close. That bracket looks like it's even farther out.

Here is a decent picture to show how close it is...

*edit* Or not....I see in a previous post you already had it mocked up...LOL

Just went through the thread. Scope Creep has been crazy on this one!

It funny, mess with a Mustang and the purists get their pantys in a wad. I didnt have one person give me crap about putting a Caddy in a Pinto.

Huh. Go figure.

progress has been very slow. I went back to school, who would have thought a Masters Degree would stall my progress... lol

I had major issues with my th400 trans i picked up back in April. The guy i got it from was super sketchy and i got screwed on the deal. I had to replace the tail shaft on it. he some how threw on a th375 tail, thankfully the trans is a TH400 and had the larger main shaft. found out the filter tube was wrong, governor was missing, speedo drive gear and driven gear missing. mixed bolts on the pan, greasy case was painted over. thankfully the inside looks good and has new gaskets and seals. I have my fingers crossed it runs okay.

I had a Champion 24" core 67 mustang big block radiator made for the car. I had the outlet and inlet sized appropriately for an LS motor. I need to adapt my F body fans to it.

I will photograph more of my goodies as i get time. I am about to take a load of sandblasted parts to get powdercoated.

Cant wait to see this running.

did a little work on my hacked up trans tunnel. i used sheet metal screws to form the patch to the floor then i cut it out with body saw and welded it in.

[Pt109]

cool project. I likw the ls in the car but my brother, however would bite his tongue off screaming about this. For those moments i just tell him it is cuz you want to win a race. LOL. I hope you are saving money for lots of tires tho.

looking at this again it looks like you duplicated the same wiring as a 10/12SI alternator? i just watched a youtube video on a 10si to cs130 conversion and the guy used a gm harness pigtail that has a resistor in line and the additional wire for the "bat" stud.



thanks again Andrew!

I don't have a wire from the 4 pin plug going to the Batt terminal. I have the L terminal going to the Dominator through a resistor and I have the S terminal going to the hot side of the starter relay, which is what I'm using for most of my additional power feeds.

im just going to use the holley alternator plug i have with the resistor already installed and call it a day!

andrew, i ordered a painless (3) relay bank (pn:30107) to trigger the fuel pump and my fans. looking at the holley hp diagram the harness already has a fuel pump relay that can handle 12 amps, i saw in a holley forum that you can use the large green wire to trigger an additional relay if you have a large amp draw on the pump. is that what you did, run a separate relay from the green power wire? the fuel pump is powered by the ecu already so it isn't a separate programmable output like the fans correct?

i will have a week off from work and school here shortly. expect lots of progress.

************* never mind! did more digging and discovered this!

I've never used the ECU's fuel pump trigger wire to directly power the pump (even if it is less than 10 amps).
I've always used a separate relay (2nd relay) because that green wire is still only 14 AWG.
The 2nd fuel pump relay is used so the fuel injectors aren't subjected to the pump's amp draw.
It's only a 20 amp fuse and it also feeds power to the fuel injectors (& ignition coils - LSx).
I prefer to use 10 gauge wire due to its long length, especially for high output race pumps.
You'd simply use the green fuel pump wire to trigger the primary fuel pump relay.

Here is what I did for the fuel pump relay:

I spent most of the day figuring out a way to mount my champion 3 core radiator I had made. I chose a big block mustang radiator but had the outlet and inlet swapped and sized for an LS motor. I originally wanted to use the factory saddle brackets for a big block but quickly realized that the way the radiator was made the tank sat on the frame rather than the repo saddles I purchased. Also the core is too thick and the top bracket would not fit. I moved to plan B and got some 1/4 inch thick aluminum bar stock off ebay and made my own radiator mounts. I drilled and tapped it to mount the radiator 1/8 of an inch from touching the frame rails. To top it all off I butchered a set of 2000 Camaro SS fans I had laying around and mounted them to the fan shroud brackets. All in all, I am please with the way it turned out.



I marked the aluminum, i still need to cut out the overlap.







I also pulled out the parking brake from under the dash. My pull handle was broken and I could not get the pin out of the handle for the life of me. I ended up cutting off the old handle with the grinder and pulling the knurled pin out with vise grips. I will replace it with a billet handle in the future.

I test fitted my 10" speedway torque converter. plugged into the trans just fine. what do you all think of this gap? its about .20, i stacked all the washers from the ARP bolts i have and its a perfect fit. do you think i should use all 3 washers or just 2 washers and pull the converter forward a bit?





I also cut up a cheap-o TH400 flex plate shield from ebay and made it work on my 5.3.



yes, i cut the "ears" off my trans case. i drilled and tapped the case to accept the shield.

I took a load of parts to the powder coaters last week. they turned out better than expected. I use all of the original parts off of the car. since the vent and quarter window frames had some heavy pits and peeling chrome i just had them blasted and coated. some of the large pits are still visible, but that doesn't bother me much.







this is the worst area of pitting on the drivers vent frame. its only noticeable when you look for it.

I just dropped off a pop open gas cap, tail light buckets, and all of the front and rear glass window trim. next after that the bumpers and my choice of rims will get the same gloss black.

[chunger]

If you don't mind me asking, what did it run you to get all that powercoated?



It looks great, btw!

not at all! everything pictured plus the door glass surround stainless (not pictured) was $280. that price included:

Vent window frames
vent glass frames
quarter window frames
door glass trim
door handles and buttons
reverse light housings
parking light housings and brackets
tail light trim bezels (6 total, 4 pictured)
headlight retaining rings

all these parts were original ford pieces, removed from the car and boxed up. they were dirty, pitted, and peeling. the shop baked, blasted, and acid stripped most of them. i cant wait to see how the gas cap and window stainless turns out!

the powder coat is far less thick than expected. the glass channels are .33 and the glass is .22 thick. leaves me with roughly .055 thickness for setting tape. i can use the recommended 1/16 tape or chance using 3/64 tape for the difference. i may try both and see what fits the best.
