I seen a BBC Camaro this past weekend at the track it was a 427.
Not sure what was all in the motor but sitting on top was a Holley 2bbl...
It had a homemade wooden spacer under it. So I had to ask the guy why and he said he runs the 6.50 index (1/8th) and needed to slow the car down..It had been running 6.50's all day long... :shock:
