race engines should not get the fuel times or the longetivity of a good rtr engine....such as the mach...they are just to totally different engines...for instance a nascar engine they ''hope'' will hold up for 500 miles...damn earnhardt jr...lol...any way but ur rtr box stock small block chevrolet should go 200,000...2 totally different engines...
You are 100% wrong there...race engines last much longer in actual driving hours then a sport engine, and they also get far better mileage....... Sport engines have nothing on a race engine other then being priced cheaper....thats all they have going for them...
