V-8 motor: whose valve covers are these?

This 800kb photo can be enlarged; this British stock car, circa 1969, has V-8 valve covers that I don't recognize. Anyone identify them?

???

 

Here's my guess...... 57 Mercury Turnpike Cruiser

 

Definetly Mercury or Lincoln 1957 or earlier

 

Yeah. Mr Clean nailed it. They say Turnpike Cruiser right on them.

 

Did you all see the kettle there on the front bumper? Maybe he's gonna syphon boiling water from the rad for his cuppa??

 

I meant first to say thank you guys for those instant and informative replies. I like the look of that car --- an Austin Mini for serious track work!

 

One interesting thing is that the extra piece on top is only on one side due to the air cleaner snout on the other side. I have seen a hotrod with 2 of the same side valve covers which is pretty cool.

 

Tommy, I just Googled the motor, and the only photos I found showed that plaque on the right-hand valve cover for that reason --- this stock car has one on the LH cover --- thanks for pointing out this detail.

 

Personally, I'd like the old (Bedford?) Ambulance in the background left!

 

Check out that home brew Frame!
What the heck?

With a big Merc mill he musta cleaned house against all the bangers back then.

Thanks for posting, this is a Great picture

Those English guys took no prisoners. Here's a 430 Merc motored maniac ready to attack, also in the sixties. Accessory #1 was the heavy gauge steel bumpers. Nowadays it's money, sponsors, good behaviour ----:

 

Yep. 368 lincoln/turnpike cruiser motor.

 

Thanks again for that info, and also apologies for loading a too-big jpg photo --- I am a bit ignorant of the how-to's, and of course have not "read the instructions" for H.A.M.B..
