I like it. ive always been a fan of the gt's more, but this one looks nice. i had an 89 gt for about 2 weeks when i was in hs, the tranny went, and i didnt know much about cars so i sold it. :/ should of kept it

the GTs are more expensive for insurance, whether its a notch or a hatch. this came with the same motor as the GT but it's like $80 cheaper on insurance than the it lol. no idea why but whatever lol.

Guess I'll be the one that says it....

In before part out. :rofl:

I really do like the look of the notch 5.0 cars. I looked at one of before I bought my trans am, but finding one in good shape is nearly impossible. And I couldn't buy a ford :coffee:. Keep it looking clean like that man.

Nope, this one isnt getting parted out. Collectively the family loves this thing. They are just happy I dont have a Honda anymore, especially since if I spend $15,000 on this thing it will be an 8 sec car. :ricer:

Realistically yes, but the money to make it go fast isn't worth it. This thing is probably 250 with the cam and exhaust but the torque is unbelievable. Something a Honda is hard to come by.

Should be getting in the 9mm wires, B&M Shift Kit, and Wix trans filter in today. Will also get more pictures.

Next working on getting the 3.73 with LSD rear parts and get them installed. .

New 9mm FRPP Wires, B&M Shift Kit, and Wix Transmission filter. Also picked up some Bosch plugs, Dayco Serpentine Belt, and a new Turn Signal Flasher.

Getting a new 100amp Alternator too since this one is barely keeping up.

No Coyote swap. Even though those Modular motors are nice, they are kind of like going from D-series to K series, they're way too smooth. This B cam is pretty nice now. I have plans for the future. After I get the 3.73s in the rear then I will be starting on the motor. GT40 heads, 1/2in or 1in Phenolic spacer, Either a Trick Flow intake or Edlebrock intake, 75mm TB, and then after that going to save up for a Pro Charger build. I'm looking in the ball park for ~500whp.

Thanks man, so far loving everything of it. Got it sideways yesterday on accident.


Changed out the plugs and wires today car is running quite a bit better now. Doing the full ignition tune-up is exactly what this car needed. Seems like the previous owner lacked maintenance. Still going to need to pick up an MSD Coil to finish up the MSD/FRPP ignition system. Going to change out the tranny filter and install the shift kit hopefully sometime this weekend. Also going to install the new serpentine belt and adjust the "TV" cable; having a little rough downshift every now and then.

Ignition switch is fucked up. Almost caught the starter on fire last week. Replaced starter and Starter Solenoid and still had the issue so down to replacing the actual switch and see if that fixes it.

Hey if you go and pull the GT40 heads off an Explorer you could pull the intake manifolds too. They are supposed to be almost identical to the Cobra one. Be careful those GT40P heads need different headers to clear the spark plugs. I think the 96 to early 97 Explorer had GT40s. 97+ had GT40P. And why not do a 130 amp alternator?
 
#16 ·
I may be getting ahold of a 429 FBB here shortly. It's a package with a C6 trans, but I'd pair it with a C4 since it is lighter and has that 4th gear. Still working this with my buddy so nothing set it stone.

Im not a huge fan of the Cast GT40P heads, they're cheap and easy to come by, but they are super heavy. I'd go with Aluminum GT40 heads if I decide to keep the 302. I wouldnt need a 130amp alternator honestly. At this point I dont run enough stuff to need that much output.

Man. You just come up with all sorts of good stuff. I have to salvage yard build my stuff. Guess that is what happens when you have a wife, 3 kids, and 1 income. What sort of size rear end are you running? I still have the stock 7.5. Figure it will probably hold with the mild 302. Awaiting 429 build. You can ship that whole 302 setup to me when you do.

It is the 8.8 rear end. Another buddy of mine has a Currie 9" rear that he is selling stupid cheap that I might jump on, but I cant justify that cost on only a C/I/H/E block right now. The only downside about looking into a 429 is the weight. I'll have to throw a couple go fast parts on it from the start just to make up for the additional weight of the BB now.

I really am considering a Kenne Bell Blown 347. I keep getting talked down because for the price of that setup, I could have a full big block possibly making more power. A big block, especially a 429 will have plenty of low end power to make up for the weight, so pretty much going back and fourth. Either way I will need to sell the rest of the civic stuff and save up more monies to get this build fully started.

Nothing new with this. Still cutting apart the civic and trying to get rid of the left over parts. This has been running just fine. It's nice getting compliments just driving it around.

Found out I had a headgasket leak, decided to replace all the other upper seals/gaskets while I was at it. Only picture I have from last weekends work.

Picking up another 302 as an interim build until I can get ahold of a 351w. If I can get ahold of a bare 351 block with main caps for around $200 I'll pick it up and scrap the interim build all together. This build will be a long one.

got the car back buttoned up, runs like a champ. going to get started on installing the shift kit and changing out the trans filter and it will be back on the road.


Also found a local 351w out of a 1991 Ford F350 Rail Truck. It is pretty gummed up with old/cheap oil but I will be picking it up once someone comes and grabs this damn K20 out of my garage.

Picked up a 460 Big Block for it.

Plans for this right now is to basically do a mild build. The torque put out on this in stock form is plenty to cruise the streets on. Looking to make well over 1 per inch, maybe if I'm lucky 1.1 per inch which would make it ~520hp/600tq.

Started last weekend with tear down. Going to deburr, rethread, and pre-clean the block to get it prepped for the machine shop. Going to be going .060 over standard bore (4.420), press in new cam bearings, and hot tank.

Got a little more prep work done today. Cleaned up some of the rough casting edges, deburred the cam ports in the lifter galley, scrapped off excess paint and gasket material. Also ported a few of the oil passages to remove all 90deg into a better flowing rounded edge, and opened up the water passages from years of build up. Going to give the block a nice pressure wash pre-clean before sending it off to the machine shop.
