I bought that Road and Track issue when it was brand new.
Yes, I still have it.
There is a lot of good reading in it, if you've never read it.
I highly recommend it. :upthumbs
Just to take the guess work out of the question and to give some of the new people something to look at , a year by year comparison list would be a great idea. Show a list posting figures between what Chevrolet offered and what Callaway offered for the same year starting with the 1987's to...

I think I should clear up some mis-information.
The only rework to the bottom end of the Lt-5's done by Callaway was to have a option to change out the factory rods for Oliver rods. These were only available when the 490 packages became available, I believe around 1995. The rods or any rework to...
Thats not completely correct.
All the Callaway 475's had a high flow exhaust as part of the 475 engine package. Note: the double D exhaust tips. It was the center outlet that was the option over the dual exhaust standard upgrade. I also have the Dyno sheet that came with my car, which were...
