Interesting too my brother knows Wayne Vanouck who was an old time drag racer and now builds many of these engines for these pullers. He told my brother the main reason he switched over was for the life of the engines. At the end of the race you are actually stalling out whereas in a drag race you are still revving up. He said big big difference in the life of the engines. He has built and designed a V16 for pulling.
On the same note a good friend of mine out here in Alberta drag races on the central Alberta circuit. He said the best thing for him is with this circuit running an 1/8 mile track. The part that killed his car was the second 1/8 mile.
