427 Block
My son is looking to build a 427 which won't be for a while. We have been looking at current mfgs. But have only found Genesis, I had seen Dove from years back but can't find them on the net. Are they still going or are they gone?

One of the FTE FE guys, Scouder, is running a Shelby aluminum block. That will cost you in the $5k range, just for the block.
Expect to pay around $2k for a decent rebuildable Ford 427 block.
Check Ebay, they show up frequently, but fetch a good price.

68Torino,
There are really only 2 block manufacturers right now. Genesis, who makes iron and aluminum, and Shelby (www.carrollshelbyent.com) who only makes aluminum. Both appear to be excellent pieces. There are starting to be quite a few engines running all of the above with no appreciable problems.
The Shelby block is a little more expensive, but I chose them because of a couple of nice features. First, the custom head studs, which are required, thread into the block farther down along the cylinder bore causing less deck distortion than a standard block that threads right into the deck. Second, the cylinder sleeves come in 2 sizes, standard 4.25", and big bore at 3.75 that can be bored to 4.44. The sleeves are also dry sleeves that can be replaced very easily.
Other than that, the only choice is a used block.
Good luck, and if there is anything I can help you with just let me know.

Thanks for the help guys! I was wondering why I haven't 'found' Dove.
Next, the point for my son wanting to build an all aluminum block 427 is first of course CI. The other major reason is he wants to put it in his '68 Torino formal roof. He dosen't want to have to do a major upgrade in suspension to carry cast iron because at a later date he will want to go back to his factory stock motor which he wants to 'cherry' out and save. He plans on running a C6 with an electronic overdrive he found looking in the catalogs. I haven't checked it out yet. He knows this is going to be along term project with a frame off and the works but he 'lost' a '67 fastback Galaxy and that always bug him so he's stcking with the Torino.
And of course we are hashing out him wanting to run 4.11s with me telling him with 500 to 700 hp in a 427 you can run 2.73s and won't be able to afford rear skins.

I think the shelby blocks are the best aluminum ones out there. They seem to be stronger and have lived at 1500HP already. He's gonna need slicks to take advantage of all the power anyways. You won't be able to gear it to have any traction in first gear on street tires. A 4 link is definitely in order too.

Thanks Ratsmoker. He won't be using it for the strip(although he will stop there from time to time) he is looking to run it on the street as a daily. No winter. He fiqures the 4.11s with some type of OD will work. I fiqure run a stout C6 with 2.73s or there abouts will do. I also told him 400 to 500 is way plenty for the street but he sees the big numbers and starts drooling.
But we'll see.
He loves his '68 which when we looked at some books found out was called a Formal Roof. These got used for the GTs. To me it's a two door hardtop no posts.

The only thing I don't like about running low gears like 2.73s and 3.00 is that with an engine like that you will obviously need a high stall converter. It creates a lot of heat when you are in the slip range. 4.11 gears will get it out of the slip range with little effort. Also cruising at 2,500 rpm with a 3,500rpm stall creates heat. I myself would feel best cruising down the highway at 3,500rpm with an engine that souped up. With 3.70 gears I turn about 3,000rpm at 70MPH and I have a 3,200 stall. It seems to stay very cool at those speeds. I have a 3,600 stall that I will be installing with my 4.56 gears. The C6 will take all the power you can throw at it if it is built right. They use modified C6 trannies in monster trucks all the time. They are the toughest tranny out there with the exception of the powerglide.

I agree totally with ratsmoker, I ran the stock 3.08 peg leg rear under my old drag truck at first with about 450 horse a 3500 stall, etc. and the tranny temp would heat way up even cruising. with the 4.10's it ran great cruising at around 3500-4000 on the freeway. I never figured gas mileage with the 3.08's, but I got 14 mpg+ with that nasty small block in a 4000 pound truck cruising at 4000 RPM and a 700 double pumper holley w/50cc pump. Not too bad if you ask me.

I think it comes down to setup. A friend of mine in the Army in the '70s had a Grand Prix Model J with a stroked 400, stock T400 and somewhere around 3.3 rear gears. This thing weighed in over 4000 lbs and would crise at 75 all day long and return 25 miles to the gallon. So if my son runs 400 to 500hp in a 3200 lb car with something in 3.00 to 3.30 I'm betting it will live and work great. Ihave run a Mark IV and a 454 Impala both had gears under 3.50 with the Impala coming in at 2.73 or so and both were very heavy and were great highway cruisers.
