Thanks for the info. I had herd the second plug location allowed for the engine to be moved back a bit for pro stock if I remember it right. I was after the Looks value. Something like this. only a 8-71 blower. I think a big 10-1471 would make to much heat on a street car. there isn,t much that can mach the looks of a HEMI with this set up,and a Blower/Enderle. IMO
