I have never even heard of that Magazine did it evolve into another? Seems you guys had all the good stuff in the old days, seems like every corvette show used to have an Autocross, a big party, and a wet-t shirt contest, or from what I gather from all the old Corvette News I have been reading.

SMR 67 said:Bob, I'm confused about a couple of things in this article. At one point it says "...there were 20 C-48's produced, 16 of them with the aluminum head engines...". At a later point in the article, it says "Of the 16 aluminum head L-88's that rolled out to do battle in 1967, only three survive today...".
Isn't this confusing the L-88 with the L-89, since there were 16 L-89's (i.e., 16 L-71's with aluminum heads) and 20 L-88's? I wasn't aware that of the 20 L-88's, 16 of them had aluminum heads, which is what the article seems to be saying.
:confused
P.S. The production figures actually show that there were 35 C-48's (heater/defroster delete). I think we can all infer that 20 of the 35 were the L-88's. But I'm not sure that the other 15 C-48's necessarily were L-89's. Makes things more confusing.

0-60 5.5 seconds
1/4 mile 13.8 @ 104
top speed 143.

Ken Anderson said:The ones we dyno'd were 575 -580 HP and with the AL heads it went way down (no heat retentation). The Hemi's ate their lunch at the dragstrip putting out close to 600HP. The MPH turned in the 1/4 were a good measure; the Chevys at 123-125and the Hemis at 129-130. Also, the 1st design L-88 valve springs were good for maybe 3 passes before #3 or #6 piston came out the side of the block. The valve train was very poorly designed (cheap) by GM for any severe duty use.
DRTH VTR said:When were they dyno'd? Pre 1972? Was it net or gross? Were the cars prepped for the strip, or were they essentially stock? Just curious...
Ken Anderson said:All were race motors prepped (blue printed) for drag racing tested in 68 or 69 (too far back to remember exact dates).
