Been working on this for awhile....
The engine is a 351C 2V backed by a rebuilt C4
This was an early mock up. I've since added an intercooler in front of a new Champion radiator edit: rotated image

Awesome! Can you share photos of how you routed the piping?

Here's the oil pick up and return, and the Puralator fuel pump I'm using to circulate the fluid to the smaller cooler mounted above the intercooler

I love it, a Cleveland on boost. How big is the trans cooler, is that what's above the IC? I'd have a large trans cooler for a serious power vehicle. The early 2000's Super Duty trucks have one that is very long(wide) and short. It should fit in most vehicles, it's as long as a typical radiator, I'd say it's almost two square feet in area. I'm looking for one or two more of those myself.

I totally agree. I tried to keep it clean. Aside from the blower, intake, MSD Atomic fuel injection, and Hooker headers, the engine (block / crank / rods / pistons / cam / heads) is stock as far as I can tell. It makes 7 lbs of boost, even moving air through all that plumbing. The MSD has a boost referenced timing retard feature. I monitor the afr with a Zeitronix dual channel ZT-4 gauge. NA it ran 14.36 @ 93.41 last year, with 3.89 single track. With the Paxton, and not completely dialed in, it ran 13.34 @ 101 last weekend. Pretty happy so far, but I'm starting a list for my next iteration ---- a t4 turbo. Edited by jbach72gts - 30-October-2020 at 1:50PM |

I have a used turbo somewhere from an Eagle Talon, wow that's been a long time since I got it(about 1999). I was going to use two of those for my 91 Mark VII at the time. Things change and I saw too much power doing that, so I stayed on a NA path, a 347 and a new 92 LSC. Have fun with that, I love the 72's.

Right above that is a small trans cooler for cooling the Paxton. Behind the supercharger cooler is the transmission cooler. Its hard to see, but I mounted them there to allow more air flowing to the ic. I dont remember the size of the coolers but could look it up. |

Gotcha, the blower has fluid in it and that's a cooler for it. I missed that before. Monitor the ATF temps, you might not need any more cooling depending on how it's driven etc.

Really nice work and great looking GTS! Of all the cars with extra room for coolers in front of the rad, the 1972 Gran Torino has got be be one of the best. There is a lot of empty space up in front of the rad support.

Thank you sir
I didn't do the paint work, but I did reassemble it afterward and replaced or refurbished all of the suspension and brakes Not nearly as nice and detailed as your build. That thing's impressive. I actually wanted to build a 400 but couldn't find an early block to go with my C4, which I'd already had rebuilt. And yup...there's an acre of real estate in front. I ditched the ac condenser in lieu of the IC If anyone's gonna replicate this, I will be happy to give advice based on my experience. One thing to note is that I changed the radiator for one a little narrower to give me the clearance needed for the tubes to and from the IC. It's a Champion CC-381 for a 69-72 Ford purchased from Jegs.

thank you, Steve
It's amazing how long it takes to get a car to this (or any) progress point, then start over again. My wife and I bought this when our daughter was first born. Took her with us when we picked it up. She was in a "bucket" (infant car seat) Now she's 15. Yikes !! Soooooo many stories. Like how my vinegar-and-water neighbor ratted on me for a shed that was too close to his fence. So I gave away the shed instead of moving it like the town building inspector wanted. Unfortunately everything from the shed had to go in the garage, and the Torino went from the garage to my dad's. So I decided pretty quickly to finish the car because dad's getting on in age,and the car had been sitting for 12 years (it was the Big Red Shelf) Thank you mr neighbor !! Jon |

Thank you Steve
The sealed hood scoop was definitely worth the effort and only took a couple evenings. The Paxton has taken way longer than I hoped. I bought it last December and its taken this long, but well woth it. I may try sealing the hood scoop to the Paxton next because under hood temps get pretty high. Or I may just yank the whole supercharger setup and try a rear mounted turbo. There's something about giving away 50 hp (minimum) that it takes to drive a supercharger.

I like this project. I toyed with the idea years ago but I'm afraid my compression is too high now for any boost.

Ditto, many late model cars have high compression and OEM supercharging. I think making it work with high compression is about the control system, the AFR and timing. An older type of control won't be able to handle it, but the number of aftermarket systems now is large. So it's doable, but carefully.

25* abdc? what cam are you running? i think your using a .050" number instead of the seat number. quick swag you can divide the difference of the adv and .050" duration by 2 and add that 1/2 to the .050" to get a seat number. typical intake valve close on the seat is around 70*-75*, 25 is crazy early |
