Any other pointers regarding chassis you want to share?

A non pressurized crank is good for 5000rpm+- with standard rods or a bit more , in my experience a pressurized crank is often more trouble than its worth forget Renault rods too much trouble.The secret of winning a highplace in the A7 world is reliability and finishing that gets you the points to win a championship! Engine runs with 15 to 20lbs (overbored oil pump) splash fed and full flow filter.Enjoy !

Only 2 bearings 😮, ridiculous

@@marmac567 Agreed. A four cylinder engine needs at least three main bearings. I can't imagine the flexing of the crank at even modest loads and speeds.

In my case. I live in an area where temperatures reach 100F during the day and with stop and go traffic my black car with a V8 swap runs extremely hot. To combat that I will need this.

I was also gonna ask this but he seems to not reply to comments i can’t quite understand the pictures and make use out of it please let me know if your any wiser than i am

@@will6635 I am sorry, I did reply on my phone but for some reason it did not record it. Anyway I explained that I did not have a drawing of the plate that was welded on the underside of the gooseneck. However it is a simple plate that follows the shape of the open section and is then bent to fit the gooseneck. It is then arc welded to the gooseneck and this stiffens the weak section. Let me know if you can follow this, if not I will try to make it more understandable. thanks for taking the time to follow my video

@@johnsutton3279 No worries ! I’m building my an ulster and i wanted to stiffen the chassis but i’m struggling to make out what you’ve done as i want take your advice on board

@@will6635 Did you do this as I am trying to do mine and I cant follow teh goose neck bit or the cross member if I'm honest

@@edwardbuck1687No never botherd cars nearly finshed i was advised it wasn’t needed

Hi, Martin. Very good to her from you. yes we are finally making progress. Having restored the original bonnet Larry has had difficulty taking a mound off it and so has decided to use the Swedish bonnet modified to fit. The engine is a 1300 cc Cosworth that was built for Andy Seward for HOO 144 but was part restored and so I bought it and completed the rebuild. Interestingly it was built by my old friend Stuart Rolt and he had all the details of it. Dry slumped and tested to 170 HP it should go very well. Keep in touch and give my regards to Gord Davidson. John

Martin, Thanks for your continued interest. Actually Larry has decided to use the Swedish bonnet after all as he has had difficulty making the mound for the reworked original one. The power unit is a 1300 cc Ford 109E unit that I purchased from Sewell who owned the Minoprio car when he was stationed in Europe. Interestingly it was built by my long time friend Stuart Rolt and he had kept all the details. It was brake tested to 170 bhp so it should go very well. Thanks and please keep in touch, john

Malcolm, Thanks for responding and well done with your Chummy. I really miss my chummy which I drove all over the UK and Europe. My youngest daughter, Lucy, still has it. Do you recall me providing the transport for your wedding with my Vauxhall 14-40. I will try to find the details and do an article about it. At present all my notes and photos are packed up as we are moving to our new house in Guyana, However once unpacked and installed I can start again. Best wishes, John

Merci it was a pleasure

Thanks

An "Ulster" is the sports version of the Austin 7. The title came about after the successful 1929 Tourist Trophy race at Dundrod in Northern Ireland. My car as shown is one of the 6 works cars entered in that race. Previous Austin 7 racing cars were designated in various other names. But after the 1929 race they were called "Ulsters" as Ulster is where the race was held.

Most cams are total worn out today we need new cheap supplies

It is a 1961 car and is the prototype Marcos designed by Denis Adams. These cars were made with a plywood chassis are very lightweight Raced very successfully by Jackie Stewart and Jackie Oliver and myself.

@@johnsutton3279 First cars were made in 1959. They made many between 1959 and 1961 when frank costin left the company. There is no way it is a prototype made in 1961 since there where many made beginning in 1959. The first ones were called the Marcus GT, often called the Marcus 1500, nickname because they had ford 1.5 liter engine. The company tried a 1.8 liter volvo in 63 that flopped. introduced a Marcus mini with metal frame in 1969 also with the volvo 1.8 litre and it failed. Company died in 1972. But was bought and relaunched in 1976 and the sold home built kits of the car. NOW I know what you have is A luton Gullwing model. Those cars were sold from 1961 and 1962 and only a few were sold. they were exclusively home built kit cars, and they delivered everything you needed to put one together. They had 1 litre engines. The chassis was put together and delivered as a whole. Those don't appear to be the original rims. The original were solid and had no vent holes. Its not really a prototype. Its more of a one off . Still it is a very nice historical car . I would make it look like a museum piece. I just love to restore unique cars. You should see the rare 64 MGB i did, first electronic overdrive car. taking it from Basket case to museum. The car you have was made specifically for the home grown GT racer.

@@josephkaminski1857 Actually they are called Marcos which is an acronym of Marsh and Costin.

Sounds like a chancer trying to aquire your historic vehicle at nil cost. Is this the actual one which you raced, or a replacement? I imagine the termites in Florida would very much like to eat her!@@johnsutton3279

o you read the Marcos history pages then...@@josephkaminski1857

This is a 1961 model and was the prototype for the second Marcos. Mar for Marsh and Cos for Costin I was the first person to order a Marcos in 1959 and went on to race it winning the Autosport Championship in 1961 and was in the winning British team for the World Cup Race at Zandvoort the same year. I went on to win the production class at the Nurburgring in 1963 at the 500 km race. The videos of these races are included

You're welcome
