I think the big hold up is NASCAR rules require rear wheel drive and most pacific rim and euro cars are front drive
Along with the fact that fuel injection isn't allowed and most of the overseas manufacturers haven't built a carb in a long long time
I know, your all gonna say nothing on a NASCAR is stock anyway
But Ford Chevy Dodge and Pontiac supply the blocks and the rear ends
I just don't know of any japanese or euro V8 blocks that would qualify under current rules
And as for Darrell Waltrip running a toyota truck
He has been for the last two years thats nothing new
