Well, I don't know about anyone else but I love your setup. Is that a GM blower? Are you using forged pistons? C'mon, give us the skinny, like C.I., heads, compression ratios, cam duration, etc. You can expect ~40% more ponies over stock depending on your blower's %. It sure beats centrifugal setups and the chrome is beautiful.
What trans? RE? Tires?

Motor is a 390 with factory 390GT heads we think. Compression is 9:1 or so, blower should run about 7 to 8 lbs boost the way I have it setup right now.
Cam is a 236/236 572/572 108 103
Tran is a C6 with a 9" out back(right now stock stall, which I'm sure will not stay in there). I haven't done anything with the rear end yet. She will need some changing when I get there.
Rear tires are 275x45x17s, not really a drag setup at this point. Same tires I have on the rear of the olds also sitting in the one photo.
I still have to finish the throttle linkage, fuel lines and get the correct belt, I ended up with one about 6" to long, and run the coolant lines. Click on small pic for bigger view.

Yeah, you need a stall converter. With your cam, driving is a fight w/OEM. Also consider a lower RE gear, just to keep the RE from breaking.
Are your pistons forged? This is important when using a blower.
Love, love, love your setup so far. - DaveMember, Sons of the American Revolution

Are you keeping the coil spring setup for the RE? (I hope you go with leafs on the same axle.)

We are thinking on the rear, we will either go with a four link, or even a HotRod's to **** setup. I do have a full Cobra cradle, but I haven't figured yet if it's width is okay, since I would like to narrow the rear end up from what it is. And the Cobra also does seem to fight wheel hop from what I've read? And if all the work that would require is even worth the effort...Comment

I love the Cobra cradle. It's so convenient and easy to adapt.
The 390 is a great engine. It shares the same crank as an FE 427. I know some folks used a 410 crank in the 390 but not sure if the Mercury is the same. If you can't tell, I prefer the 390 because it's commonly available everywhere and so much can be done to it because of aftermarket support.
My next choice is the 351W-based 427 (Coyote) engine. 351Windsors are everywhere because they are SBF. Ford put them in Mustang Cobra, F-150 Harley trucks, Lightning trucks and a host of full size cars. Great engine, great support and many come with roller cams and EFI. - DaveMember, Sons of the American Revolution

The Cobra rear end I have seems perfect. LSD with 3.73 gears and the axle shafts are massive. Has a nice stout sway bar. I'd just need to fab up a way to mount the cradle under the car. My one worry is the width, I haven't sat and looked hard at it yet.
I actually picked it and two Lincoln 8.8 cradles from a client when they were available. Reason I grabbed them was for our CTS-V, but then I read what the balance of that conversion was costing and kinda halted it.
He had a 56 TBird with a supercharged Coyote and the Cobra 8.8 out back, and the cradles I grabbed were "extra"Comment

Your 9" is actually stronger than the 8.8 and I don't know if I would trust the independent axles with that much HP. All you need is a pair of leaf springs and four perches from a '59 or '60, bolted to your 9" axle.
3.77 may be ok for your C-6 but you're crankin' over 500HP. I wouldn't go any taller than 3.90:1. I ran a 4.30 posi in my Mustang for many years but it was fed with an AOD. The C-6 is stronger than an AOD but you're limited to three gears.
Here's something that will help you... The sun gear from an E4OD will fit your C-6. First gear will be ~20% lower, second will be ~15% lower and third is stock (straight through). I did this on my C-6 and it really helps a tall RE gear. You still need a stall converter. Any good gear and axle shop should have parts, or know where to get them.

Bryan - you might want to send a PM to Tom Wollenburg (Tom's bird) here on the forum. He is currently installing leaf springs on his '58 and replacing the springs (along with rear discs and some other upgrades). Guess that could help with the decision.
Tom's a super nice guy - I'm sure he can give you some details on what was needed.

Whats the plan for the hood? Pins?
Otherwise love it and do agree that you should leave the 9".

To be honest, I have not been worrying bout that stage of the build till I get there.
I've been trying to do this without making un-reversible? changes to the car, so far I have accomplished that. Right now I can still pull this mess out and stuff the original drive train I kept back in, if I was so inclined anyway.Comment

On my list is doing rear discs, the drums just get in the way.Comment

The width of the 8.8 isn't much different from the 9". Mustang GTs used straight 8.8 axles. Cobras are the exact same body with a cradle bolted on instead of the straight axle. The big difference is, independent suspension.
Your 9" is actually stronger than the 8.8 and I don't know if I would trust the independent axles with that much HP. All you need is a pair of leaf springs and four perches from a '59 or '60, bolted to your 9" axle.

NICE! Curious to see what you do with the hood. I am also going to have to modify mine at some point.
mattyel is going to have a blown 460 in his car. I've seen some pics on facebook. (he lives in Australia)Comment
