Guy Edwards had one in a Lola T290 in 1972, there was one in Luke Duffy's Crossle 22F and Nicholson used one in a March 752 in 1976.

The Nicholson motor was later fitted to the Kaditcha SR781,as far as spares go some guy in the States bought what was left at Cosworth and the production type engine features different things such as different inlet/exhaust stud sizes,extra retaining bolts on cam cover and different cam gear mountings.I have a spare head valve area part but the rest like the crank and rods i have had locally made(Australia)Another thing they used small block Chev crank pin sizes and the bearings are the same except for the rear main.

They would have made an excellent USAC midget engine ,i have had a full seasons experience running a COSSIE ford BDP in a STANTON USAC midget...Originally posted by A E Anderson
I believe the first two or three Cosworth Vega engines that Chevrolet released outside the company went to Bob Higman, the reigning USAC midget chief mechanic/car builder, in 1974/75, for installation in a midget. The car went like stink with that engine, Pancho Carter being able to pull "wheelies" almost at will at speed in it.

Look at the top of the thread list for a sticky titled "ATTENTION EVERYONE Solution for posting photos".
On the first page about half way down is a post by Bira with comprehensive instructions on how to use Imageshack. Works for me.
Cheers,

Never heard of that one, Dan - what car was it in?

Thanks. Actually that does set the faintest of bells ringing, but as I was otherwise occupied for most of 1978, I'm a bit blank on details. Any idea who prepared the engine?
Pity Derek Lawrence never got his hands on a truly competitive F3 car - he was a good driver and flew in the "Team Titan" FF cars a few years before.

I think Titan did something with the Vega engine. Whether there was any connction with the Cosworth engine, I don't know.

I have just checked up on this..cousin Oz at Titan put me straight.
Titan actually bought all the Vega parts from Cosworth . Blocks, heads, cam and crank blanks.
They built at least two up as F3 engines. Mike Blanchet had one in a Lola, (T270 in 1979 according to the Kettlewell book), and possibly Mike O'Brien ran one in a March. If Derek lawrence had one it didn't come direct from Titan, but Oz does recall him having one in a Chevron.
Of course the significant thing about the Vega as a production engine was that it had an aluminium block with no liners. The bores were just etched, or something. (not Nickasil coated). However the Titan (and I assume Cosworth) racing versions had cast iron liners.
Ultimately Titan gave up with the Vega block but did quite well when they used the Cosworth Vega head and crank with a Pinto block to make a rallycross motor they called Rallymaster. John Welch did well with it.

That doesn't sound like a promblem to me. In any case, apparently the production engine eventually had to resort to liners.
This is worth a read.....

(Lotus were initially involved too, it is suggested)

I seem to recall an alloy with a high silicon content being involved, along with the tem 'hypereutectic' being bandied about as the latest buzz-word.
Any thoughts?

I don't recall Mike O'Brien's March in 1980 having a Vega, Toyota I think.

Now David mentions it, I think Mike Blanchet did attempt to use a F3 Vega in his 79 Lola. It was the T770 tho' David, not the T270, the latter being the 1972 Indycar I think.
Dan, it said T770 in the Kettlewell book, and stupidly I thought it was a miss-print and changed it! Not my best area of knowledge

The REYNOLDS Chev v8 product ran in both linerless & linered form, it is still not perfected TODAY?????????????????.Originally posted by 2F-001
I've always assumed that Chevrolet's linerless-alloy block technique that was the basis of Cosworth's EA ('Vega') was the same as that employed for some of the later McLaren CanAm motors - with the material being, presumably, a Reynolds product.

Somewhere in the dusty boxes, I am sure I have pictures of the Martin BM16 - it was one of my favorite cars of the day, painted rather striking orange! I'll post if I can find it!
