So what's up at the Doghouse these days?
Yours truly has been a busy ol' Mutt.....Marco's stablemate has officially entered rehab.
Today, a buddy of mine came over and we got the nasty old 351 Windsor and the even nastier old C4 FMX trans out of the Mach 1. Got the engine torn down too......and I have encouraging news on a couple of fronts there. Stay tuned. So here we go.....ready for extraction... Extraction......(blurred my buddy's face....don't want him falling victim to a croc attack at some point) On the stand......Pretty nasty....wonder what it looks like inside? Let's have a peek inside....shall we?? Lifter valley looks pretty clean....no sludge to be found. That's a good sign.... Not too bad! Let's dig in a little further....BTW...there's an easter egg here...let's see who finds it. Tiny ridge in cylinders....very tiny. Pistons came out easily. I think this thing's a builder Wonder where my buddy left the heads.....OH...here they are.... It ran rich for quite a while....plugs showed the same carbon buildup. Here's what it looks like inside 4 of the lungs....I put oil pan back on with two bolts to catch any oil that drips until I can get it off to the machine shop. Pretty damn clean. Now the old C4 "Cruise-o-Matic" was another story....YECHHH!!! It's going off to Southwest Gear for a rebuild when I get a chance. I think it has Ebola....it's leaking from every orifice possible. So there's where we stand so far.....goal is have the car back on the road by August. Also going to up grade the Armstrong steering to power while the motor is out....much easier to get to. Got a lot done today. I'm exhausted....gonna go scrub up and hit the hay early. |

Looks pretty good to me, I've done rebuilds on much worse looking Mustang engines. Also, that C4 can be replaced pretty cheap if necessary. They are a pretty simple rebuild as well.
Are you going to have the block and heads machined and rebuild it yourself? |

I know this engine has been gone through before, and I don't think it got a ton of miles afterward. I was really surprised how good it looked inside. The C4 will go off to SW Gear. Bob quoted me $550 to rebuild the trans and the torque converter. He's done a lot of work for me in the past, he'll do it right. Quote:
And I'm just doing a stock build on it. I've been down the hotrodding road tooooo many times, and I know how slippery that slope is. This car will never see the track....I'll take cheap and reliable, and leave fast for the young guys. |

Isn't that a lot of carb for a basically stock 351? I know it'll breathe better in the upper range, but I'm considering a smaller carb for throttle response on the bottom where it's going to spend most of it's time.

*** CORRECTION *** Sorry, just looked in one of my old books, the 4300 was on the 390 and ran out at 650 CFM, may be what you're looking for. Too many years since I did a Stang to trust my memory. |

I once had a rare 725 cfm holley vac sec carb that had small venturies that really had some throttle response. It ran lean on the top end though, my 11:1 355 was too much for the metering it had. I believe it was originally designed for a high revving 302, but point being it was an interesting carb that kind of fit in between the straight 600 cfm and the double pumpers or big cube units.

Summit has a CFM calculator on their site too. If I put in a max rpm of 6000 and 351 cubic inches, it recommends 517 cfm for street and 670 for strip

That was why i said good choice. i only have experience with Holley not Edelbrock. But for an engine that was factory set for a 2 brl I assumed it would be cammed and valved for it as well. So unless there is a cam head change I thought a 600 would work without over carbing. I do remember the Holley being very easy to work on and tweak.

Looks like a fun project Friz, I see you have a solid limited rust body to start with , that makes it alot easier to get the end result perfect..Why is one of the pistons different from the rest???. Is that the Easter egg you spoke of ??WW

I was wondering what was up with your project Friz. I'll bet you can't wait to start putting the pieces back together. Looking good so far

I do like the sound of a 4bbl opening up, but I have seen 350 cubic inch cars run 13's with 2bbls. Those motorcraft carbs are sooo simple to effectively rebuild, I would keep it around.

Yes, almost no rust in the structure of this car, but I have found some things that need to be addressed. One shock tower has some cracking I will have to weld, and the heater core had leaked for a lonnnng time....pinholes in pass floor. There are quarter sized cancer spots on rear quarters, but under carriage, trunk, torque boxes, everything else is solid as can be. Quote:
I found a ton of bubbafication on this car along the way. Wrong headers that didn't really fit correctly and leaked. The P.O. also routed the speedo cable between the header and the floor pan.....yes, it melted. Torque converter nuts were loose....no more than 8 ft lbs on them. They would have come off at some point. Rear trans mount was gone....as in just chunks of rubber. Left motor mount had wrong bolts....which wouldn't seat, and thus were loose. #7 spark plug was finger spin loose. It's a wonder this car ran at all, but it did. I bought it from a buddy and he drove it home when he bought it. It then sat for 10 years until I got it. I'm shooting for an August 1 maiden voyage. I'll keep you all posted. |
