A couple of summers ago I had a conversation with a "good old boy" NASCAR team mechanic who, along with one of his team's cars, was apparently satisfying a sponsorship commitment by appearing in a Grand Union supermarket parking lot in P'Town (of all places!!!). We talked engines a bit while the mostly gay crowd walked by in complete indifference. I asked him about the cylinder heads and he said that they "machined them themselves out of billet aluminum." Btw, the tubular steel frame had very nice weldments, and the body had surprisingly good fit and finish.

The engines are manufacturer specific.  However,
they no longer resemble anything in a production
car.  Example:  I saw a supposed "small block
Chevy" NASCAR motor.  The cylinder head did
not resemble in any way anything in either the
old small block nor the new LS1 series motors.
It was sort of a cross between a big block head
and the LS1 head, without the adjoining ports
of the old small block.  Another example is the
Toyota engine - it's completely NASCAR specific
with no resemblance to anything else Toyota.

Hey guys:

Paint work aside, what differences exist between a NASCAR Dodge, Ford
or Chevy? Does a Toyota have a Toyota engine? I know NASCAR supplies
a sealed black box to each car that limits revs, etc. Is NASCAR truly
single spec racing or if not, how much difference is in the cars? The
bodys are identical.
