Interesting that the same question was asked 14 hours ago.
But the main difference among the Cup, Busch and truck engines is the size of the carburetors -- 830 cubic feet per minute (cfm) in Cup and 390 cfm for Busch and trucks -- which allows a richer air-fuel mixture in Nextel Cup. According to the NASCAR media guide, the torque is 550 feet per pound at 7,500 RPM for Cup, 535 feet per pound at 6,500 RPM for Busch and 535 feet per pound at 6,500 RPM for trucks. That gives the engines the ability to produce horsepower in the range of 850 at 9,000 RPM for Cup, 750 at 8,400 RPM for Busch and 750 at 8,400 RPM for trucks.

Wheelbase 110" 110" 105" 112"

nothing really ....it's similar to major and minor league baseball...with the Busch series being the minors. Actually it is the carburator that is smaller, not the entire engine. 105" wheelbase, Nextel has 110". Busch cars are about 100 lbs lighter. And Busch cars are limited to the number of sets of tires per race.

A lot!
What you do in a Busch car doesn't really help in a Cup car except for the "tendencies" of the racetrack.

HP and weight are two of the major differences.
They stopped running V-6 back in the late 90's
they run a V-8 with 9 to 1 compression ratio.

. The Busch cars have less horse power and a shorter wheel base. They are also lighter. The biggest difference is the aerodynamics's of the car.

The Busch cars are wider I think, and slower.

Well, first thing their lighter, and they have smaller engines. Then, if you compare them to the car of tomarrow, There are many things different. For example, busch cars have no wing on them.

The Busch cars are lighter and have smaller engines so they have less horsepower then the cup cars.
