Even though I have not tried a crate engine yet I know about them. The car club has given away about every version you can think of up until last year when we gave away the H.P. version with rollers,aluminum heads etc. In our area the local dirt track boys have classes that run nothing but crate engines and the ones I talk to say they are holding up very well. And, as mentioned above give "uncle General" (chev dealer) a look before buying else where. If you know someone you may even be able to get a discount.
