My last dragster had a std valve body in it. I usually had about .030-.040 delay in it on a .400 tree. It was a fairly short wheelbase suspended dragster...215"...
My present car is 235" and way slower reacting.....

What makes the longer car react slower? chassis design? the fact that it's just longer? engine combo?
