Yeah, I remember you six-cyl SOBs giving me a run for my money at the highway 
speeds you were going! I did that 304 all wrong. I made the heads flow then 
put the wrong cam and axle in it. Dumb.

When I bought the current 258 from Mark, he'd got it from a Jeep friend who 
started to build a hot 258 then abandoned it, gave it to Mark. I bought it 
from him, he said it had a "hot cam". When I got it installed and worked out 
and found it idled at 600 rpm silently with high vacuum I assumed that 
the "hot" cam was... "stock". I guess it's not. I wish I knew what it was so 
I could repeat it! It gets good mileage yet goes like hell.

Weber 32/36 DGEV is about perfect, both in numbers and seat of the pants.

OK I'm a convert. What cam did you install?
