Mk IV, Superblower, CRS and other Continuation Cars Forum / Re: Mk IV conversion 302 small block to big block 427

Thanks Wescott !

Now the 5 speed TKO is in and I'm now working on constructing the engine mounts. I've tried very hard to keep the spirit of the Mk IV, meaning I've kept the glassfibre footwells, despite them being 3" wider. That alone took 2 months. I'm also keeping the under car exhaust, albeit a new larger diameter system.

…….and yes the bonnet does shut !

As of 2.30 this morning, after 7 months of intensive preparation finally, the big 7 litre 427 engine is able to check out its new home.
Thanks to Barry Rabotnic who built the epic motor and all my friends in the FB and other AC Cobra online communities.
Still a lot of work be done, but looks like I won’t be needing a Tesla just yet.

Rare opportunity to acquire this engine at hopefully a bargain price. I suspect the car that the engine is fitted to is unregisterable on the U.K., so a rare opportunity assuming anybody has a use for it. Shelby fitted 428s to the original Cobras. Engine of course needs verifying.

Lot 134 is a 1998 Autokraft Mk III continuation with a 427 engine, similar but not quite the same as above. These cars seem to have difficulty finding the right owner these days, although the original owner owned the car for 18 years. But maybe he was once made of the right stuff, right Steve? 😀😀😀

I think you may well be right Barrie, that the film will focus on the GT 40, but would be very surprised if the Cobra were to be ignored. Anyhow a film on the GT 40 story I welcome. Even a Hollywood version. I think Ron Howard's (Happy Days) film Rush, covering the F1 battles between Lauda and Hunt, is if not the, one of a very short list of the best motor racing films of all time. And Ron hadn't any knowledge of F1 before he directed it. So I for one will wait and see.

Bear in mind, Autokraft only built 11, 427 Cobras and many of those were LHD. Of the handful of original 1960s 427s in the country, most owners will want to maintain the original registration. So the market is very limited.
You might want to try a Cobra replica forum. AC 427 sold at auction a few years ago for around £9000.

 Finally the new design pedal box and relocated/remade steering column were finally welded up and installed today. I'm pleased to have been able to optimise a specific design for the Mk IV and improve on the standard parts, that were not really designed for this car. The new pedal box should be superior to the standard item as it will be attached to chassis at the bottom.
 We've fought for every 1/8" in this incredibly tight packag and the offset pedals are normally a big problem. But despite the new OE spec 16" Mota-Lita steering wheel, we found we could relocate the all new dual ball bearing steering column, 1" to the right. This allows proper clutch operation with the sole, not side of your shoe.
 It might look simple and obvious but everything is CAD designed and CNC'd with compound angles everywhere. Its rock solid and the steering is smooth, with no play or binding at all.
 Next will be remanufacturing the footwells to their original state. It will look unchanged, but the gap between them will be 3 " wider.

 Well done DKP for taking the trouble to post the images again. Good info for the few members (like us) who are not frightened to improve our Mk IVs.

 Don’t quite get the question. If the DVLA don’t suspect anything, the cars would get registered in the new owners names. I’d like to think of both care we’re registered in the U.K., the DVLA would have a flag system, that would highlight the duplication.
 But if the cars/owners lived in different countries, well there probably wouldn’t be any cross referencing and any problem. The DVLA isn’t Interpol.

Narrowing, prior to shortening the footwell.

Project 427 FE Mk IV

Made some real progress yesterday. Drivers RHD footbox cut out and narrowed,  pedal box cantilever frame cut through......all without sawing through alloy body, just 3/4” away. Now all set to shorten the box as no longer have to accommodate cable clutch quadrant. Determined that it will look factory to untrained eyes. It’s one thing that is working with me and will introduce more air into and out of engine bay, now the wing vents are unrestricted.
 Next will be shortening the pedal box, moving the column 2” where it exits into the engine bay.
 We will make a one piece bulkhead to bulkhead transmission tunnel, so the gearbox, bellhousing, clutch can all be removed from the interior, leaving the big motor in situ.
 All the experts have told me that you can’t make a good job of this installation, but that doesn’t mean you can do the best job that’s been done. Maybe a better job job, than even Autokraft did of the 11 427s they made. Certainly there’s room for improvement there, despite the Mk IV being a generally very well constructed car. Even has a prop roll hoop as standard. I wonder how many Mk IV owners know that?
 I’m also aware that in the end we have to detune the engine a little to make it more driveable, but that’s months and months away.

Thanks. I took the dash off yesterday (one of the few easy jobs) and saw the rivets. However I think they might be securing the footboxes too. I don’t have access to the big head rivets Autokraft used, but I guess could use washers when refitting.

Hi DKP

 I am putting in a 427 FE. I have to narrow the RH footwell 4 cm on the engine side and make it 2 cm wider on the outer side where the revised pedals are. When it is finished I want it to have the same factory appearance as before. To modify properly I have to somehow take out the bulk head pressing.

Mk IV, Superblower, CRS and other Continuation Cars Forum / How to remove polished bulhead pressing ??

« on: February 07, 2018, 19:10:53 »

Does anybody know how to remove the stainless bulkhead pressing at the back of the engine, bay without  removing the body? My engine bay is empty and I have undone the two screws underneath and the heater grommets. It flexes at the bottom, but its still held fast. It seems to be stuck under the hoop that supports the scuttle. If I just pull it will surely bend and distort, so if anybody has any further info, I'd be grateful to learn how its actually attached. If it's just glued for example, I could heat it up. Thanks.

Hi Hobo,
 All good information thank you! The point about exhaust diameter is interesting and you might like to search You Tube for a series called Engine Masters. They seek to explode myths about engine tuning, exhaust diameters for I think 400 and 600 horsepowers, X s. H pipes etc. Its a very cool series. I think on a 600 hp unit, 2.5" vs 3" exhaust pipe loses around 20bhp, but of course that is irrelevant if we don't have space of a 3" pipe! I am going to try for an underfloor system, but I don't want the down pipe in the footwells. I have another idea for that. Did you know the original 427 had footwell fresh air vents?

Thanks for reminding me about the O2 sensors, forgot about those.
 
I will wait your findings with the 0.64 OD. I was a tough call and sounds like we are both objective enough to say which is best.

 You will be pleased to know that you worried me when you said, the starter was very tight on the chassis. I thought I missed something. So today, I did another virtual fit and you can see it looks okay. I'm using a high torque Powermaster, Mini-Starter. this is much smaller than OE. If you already have that maybe the 460 is different. My engine is offset 12.7mm with the crank at 2.5 degrees to the horizontal.

It's taken forever to undo all the 302 EFI engine connections, but am almost ready to lift the engine. Will try not to drop it
