No Man! I was on the laughing gas. You know the nitrous. The only thing was i lost a carb linkage. so the hp was screwed and i had to shut down. the those cars that made big hp numbers were the real deal.i dont think the fan belt made that much of a difference.as far as engine size those engines could have been a little more mild than the smaller ones. also the air was a little different which caused things to be screwed up a little on some cars not mine but some.
