Bob, how many big blocks have we seen gernaded at willow springs? I have seen 3 in 3 events. I think that the biggest differnece is durability. In 2 years, I have put over 5500 miles of street and track on my 358ci motor. I adjust the valves, change plugs and
oil. Thats it. I have never done anything to the motor. Maybe I am on borrowed time and maybe a big block will beat me down a straight some day, but it has not happend yet. Mcfez, you may whip me on a road course some day but it will be because of the driver not the motor. I think the 358ci is wonderful. I have a number of winston cup drivers as clients and some trans am drivers too. These guys are not afraid to drive anything so the comments on the other post about fear of 427's is hard for me to believe. Also, I have been to the drag strip at least 200 times. I find it hard to believe that Bandits cobra, given to a friend, makes a pass and turns 10.50's on a true street tire. That would be a world record for cobra's on a true street tire. That kind of time is more likely to come after 200 passes and numerous tire presure and chassis adjustments, if it ever comes.Even at the drag strip it comes down to traction more than power. Other than bragging rights in a parking lot or gas station, I see no advantage for a big block. Scott
