During that era, I had a bright red Mercury Comet Caliente with a hi-pro 289. Fitted out for drag racing and daily driving. Fenton mags. Hurst shifter. Traction bars. Had lots of fun with that thing in high school at the local, informal, drag races. Good against anything comparable, and a lot of cars with more hp... but couldn't touch the two Chrysler hemi's that friends owned.

Nice wheels on the Chevelle! Too many go for the big, modern wheel with a bit of rubber stretched around the outside which is out of keeping with the rest of the car.
Those look "right".

I saw this one recently. Mercury Racing 7.0 SB4 engine rated at 750-hp powering this Chevelle.

Always admired the design of that-era Chevelle SS.

I love those 66-67 muscle cars, all of them; The GTO, Chevelle, Hemi 'Cuda the 427 Fairlane and even the lowly R-2 Lark.
I remember going to the Baltimore plant in 1966 for a 4 hour tour of the "line" and watching those Chevelles being built. Especially interesting was the 396 model coming off the end of the line, a man in white coveralls jumped in, started it and driving onto the rollers which had a large "clock" showing MPH he ran them up to 100 mph and then out the door!
A buddy put down his deposit right there, and he may still have that car.

The 396 Chevelle was very tempting but I am a Ford guy... and worked then as an apprentice mechanic at the local Ford dealer in Alexandria, Va. (which was also an east coast distributor for Shelby)

(Those "muscle cars" were deadly in the wrong hands, and still are. Two close friends (one was a lover) were killed in separate GTO incidents. Two other pals were killed in a 440 Belvedere, they missed a corner and hit an oak tree head on at something over 100 mph. The local PD left the car there for several days perhaps to influence the impressionable youth in town. The grill was perfectly formed to the shape of the tree and under the dash, the engine was in the front seat. It worked, I remember it like it was yesterday)

Nice clean installation, as we used to say...sanitary

Did I say clean before?

Skip, you forgot to footnote your source!
Hotrod Magazine: Where It All Began (http://www.superchevy.com/features/1809-street-beast-big-block-powered-1967-chevelle/)
It’s a good article, with details on the owner’s intention and process.
I check in at HRM about as often as I do here!
All the best to all y’all!

Those look "right".

The article details the owner’s intention and design decisions, the selection of the proper size tire in relation to the wheel, which were finely calibrated to produce, with a modern wheel, exactly that old school look that you and I respond to so deeply.
