Why use the GM Crate 602 instead of a GM Crate 604 as the LAMOT engine?
The GM Crate 602 has a lot of power (350-400 hp) and has been widely used on the dirt and asphalt divisions across the country. The DIRT Sportsman division, which has used this engine, has fields of 20+ cars weekly. The 602 currently sells for $3,300 (plus tax). The lower cost and No-rebuild rule will allow more teams to move up to a Late Model class. When factoring in the cost of a refresh to a custom built or 604 crate engine on a yearly basis, the 602 which can last multiple seasons without being rebuilt, makes it more economical to the weekly racer. GM does not sell re-seal bolts to engine builders, they only come with a new motor, making the engine more tech friendly. The difference between the LAMOT legal 602 and the 604 is approximately 50hp or only 12%. The 602 works well when combined with the longer lasting Goodyear tires.

Johnson, Mike Ticco, and Jason Gwin will be entering their 3rd season in 2010 with LAMOT on their original 602 crate motor with no-rebuilds. The cost of the motor: $3,300 averaged out over three seasons = $1,100 is substantially less than teams are paying for their engine programs in other divisions and that doesn’t factor any $ gained back if selling
