its funny how some things will always be the same, one engine is better then the other. Now I remember guys were running 327's and thought 350's were junk and heaven forbid if you used a 400 with its steam hole heads and short rod design. They laughed at me also when I built my 400 but 10's and street tires (M&H's) became reality, no juice either. yes it was lots of work and money. But LS1 or LT1 can both run depending on mods. heck my friends class car has a 267 Wayne County motor (for you older guys) that runs mid 10's at 12000 RPM
