Drain plug on Type 9 gearbox

feeds@kickapps.com (Lecrin) — Fri, 19 Feb 2010 16:49:28 PST

Hi all (he said, shuffling his feet). It's taken me 3 days to pluck up the courage to ask this, but will some kind person tell me where the drain plug is on my Ford Type 9, 5-speed gearbox?
Thanks, David.

Destroyed water pipe on V6 inlet manifold.

feeds@kickapps.com (snowman40) — Sat, 16 Jan 2010 12:58:01 PST

I need to get my car back on the road, but when I looked at it recently, I found that a water pipe on the inlet manifold had fractured and crumbled to dust (it's shown where the water powdery residue is)

Does anyone know where I might be able to source a replacement and whether it's a screw or push fit into the manifold?

Cheers.

Help on engine/carb fitting.

feeds@kickapps.com (Hillclimber) — Sat, 16 Jan 2010 09:51:29 PST

I dropped the engine in the car yesterday and have some questions aimed at those who have experience of V6 with Holley carb type 4160 or a 4 barrel.

You can see that the carb sits about 3" above the scuttle where the bonnet sits down, thats about 2 1/2" too high and without a proper air filter. The throttle lever is within 3/4" of the valve cover so I cannot reduce the inlet manifold height.

If I turn the Holley by 90 degrees, throttle spindle in line with the crankshaft, I can drop the carb by about 3", since you can see I have one of the Burton Power "High" inlet manifolds.

BUT will the carb work OK in this position?

Otherwise its back to the drawing board and 3 downdraft Webers or 6 throttle...

Electrical issues....

feeds@kickapps.com (cplyall) — Thu, 24 Dec 2009 17:32:25 PST

I am beginning to have some issues with the electrical system in a 1970 gt (converted to a 3.5 rover V8). Initially, water was affecting the old-style fuses and i subsequently took it to an auto-electricians to get a new-style fuse box fitted in the hope of making the car a little more reliable.
After getting the car back, it still was not completely right and has since developed more problems. Due to this, i am considering trying to fit an entirely new loom, as this would be a much longer term solution rather than trying to bodge what is already there...
As i am completely new to the idea of auto electrics, i would be grateful for any opinions/advice you guys could give me. If anyone can recommend a good auto electrician i would be very grateful!

Thanks

Half Shaft Flange

feeds@kickapps.com (Hillclimber) — Mon, 14 Dec 2009 19:56:56 PST

Getting desperate to find a replacement wheel flange for a Salisbury 7HA - tapered bore. 1 of mine got seriously damaged in trying to remove it. 40 ton press and reddish hot and it still did not break off the taper + keyway.

Axle Location

feeds@kickapps.com (Hillclimber) — Fri, 11 Dec 2009 19:15:09 PST

Whilst the refurbed axle is in the car, what is the correct location of it?

Obviously central about the chassis members controlled by the chassis/panhard rod being eqi distant, but what about the angular position as both my upper radius rods are adjustable. Is the prop shaft flange vertical? or the horizontal axis of the diff parallel to the chassis member or what? Any ideas?

Supercharged V6 way back in 1988

feeds@kickapps.com (OldNoccer) — Thu, 19 Nov 2009 01:12:55 PST

Reading Marcos Owners Mag no 57 from 1988 I was surprised to read about a supercharged V6 Marcos reg no Q 412 LKH - which was being used in Drag racing and hill climbs. The supercharged engine was producing 320bhp in hillclimb spec, and 500bhp with nitrous on the drag strip - which for a 3 litre V6 sounds completely amazing.

There are photos and quite a description in the mag, but for all I know you guys might already know all about it and where it went (my suspicion is the engine grenaded and took the car with it !). However it had clocked a 12.36 and 125mph quarter mile in what looks like road legal trim - which is not bad.

Anyone know of this car? - it was based in Goole, Yorkshire. Owner was John Yardley.

Exhaust Noise

feeds@kickapps.com (cactusdave) — Wed, 11 Nov 2009 15:34:03 PST

Whilst I agree that our cars have nice sounding exhausts, people who run Hill Climbs and Track days have other ideas. They typically want a noise limit of ca 95 - 100db ( at 18in/0.5m) My car is ca 105-110db with standard Marcos Exhaust. I have tried inserts from Carbuilder - no effect. Has any body else solved this problem eg fitting a different silencer or extra silencers. I am of course going to do more track-days and join the HSA (Hill-climb and sprint association) so need to reduce the sound level preferably without reduce power!

Improved Braking

feeds@kickapps.com (cactusdave) — Wed, 11 Nov 2009 14:19:42 PST

Since I now have a tuned V6 engine. I improved the brakes by fitting Wilwood 4-pot calipers on the front with greenstuff pads, vented disc and improved linings for the rear std drum brakes. I don't like the standard 'plumbing' system ie rear brakes plumbed in series. Has anybody improved this setup eg by fitting twin master cylinders or plumbing in a different way with a bias valve? I don't yet want to go to the expense of fitting rear disc brakes.

Salisbury 7HA Diff

feeds@kickapps.com (Hillclimber) — Sun, 11 Oct 2009 18:40:52 PST

Hi

Has anyone overhauled one of these, if so do you have any info on refitting tolerances, end floats etc. and procedures.

Also who stocks the new parts required?

Suspension Bush's

feeds@kickapps.com (Hillclimber) — Tue, 29 Sep 2009 19:50:37 PST

I am advised by MHS that they do not supply replacement "Superflex" bushes for the 1969 V6 steel chassis radius arms.

Has anyone installed a set, if so which ones?.

I see Superflex list a set Number SPF2111 for a Marcos, but which model.

Any help/advice appreciated.

Axle Identification

feeds@kickapps.com (Hillclimber) — Tue, 01 Sep 2009 15:32:09 PST

Hi

Need some help to identify the axle fitted to my V6 - 1969. It,s cast iron with a tin plate rear cover and fitted with both oil level and drain plugs.
Its 52" wide from wheel flange to flange.
The main tubes where the radius arm brackets are welded on are 2.25" diameter
There are 18 splines on the half shaft, bearings are Timken 14276 and inner oil seals 3HA 027
9" diameter brake drums fitted with 3.58 diff ratio (43tooth wheel and 12 tooth pinion)

I suppose its an Atlas from a Capri?? if so which model with the unusual diff ratio.

Gearbox and Axle ratio's recomendations

feeds@kickapps.com (Adrian2) — Mon, 31 Aug 2009 17:32:00 PST

Does any body have any recommendations of whats the most suitable ratios for the gearbox and rear axle on a 1970 steel chassis V6?

My car is currently fitted with the original cortina axle that has a 3.77 ratio along with the 4spd gearbox with OD that has the following ratios
1st=3.163, 2nd=2.214, 3rd= 1.412, 4th=1, 4th+OD=0.82

Having looked at the different gearboxes available there doesn't seem much advantage of fitting a 5spd gearbox as it won't really improve the ratios the only advantage is a stronger more reliable gearbox.

In my opinion the best way to improve the drive ratio is to change the rear differential. The easiest change is to fit a 3.54 differential for the english axle (expensive and quite rare).

The other option is to fit a Atlas axle available ratios are 3.09, 3.22, 3.44 and 3.75 this would be stronger. However it would have to have the mounting brackets fitted, made narrower so it looks ok as i don't want...

V6 Essex Engines

feeds@kickapps.com (cranniev6) — Fri, 21 Aug 2009 17:12:07 PST

Can anyone provide guidance in respect of the essex engine?

I need a replacement engine, but need to know how to spot and avoid the early Zodiac engine (with the oil pressure problem)?

Do engine numbers identify them?

Is it possible and easy to replace the essex with the cologne, or should that be avoided?

Thanks cranniev6

I have miss-matched wipers (black & s/steel + different arms/wiper sizes) on my V6 & want to replace them with suitable components.

Can anyone tell me what the originals were? And maybe a source?
