The worst thing about the crate motors is the authorized rebuilders/sealers....they are contracted to inspect for legality and seal up legal motors...they also do rebuilds. The rebuilds are the problem. Anybody who goes and buys a crate engine straight from the factory will get blown off the track by the rebuilds. Look on the classifieds for crate latemodels and you will see ad after ad selling a USED crate motor built by so and so for 8-10 grand...the autorized sealers also go in and tolerance and bluprint everything right to the limits of the specs and charge handsomely for it. Even though you don't gain hundreds of ponies from the tolerancing you gain enough to see a big difference. Thats the worst thing about underpowered racecars, a little extra goes a long long way. Thats why a legal briggs go-kart motor sells for 2 grand these days, they have found another half of a horsepower which is a big deal on something that only had 5 to begin with.
I love the comment above about people who have to spend 50 grand to outrun 10 grand... why does it seem like the majority fit in that category these days?..haha
