I agree if it is a LT1 style block and it is still reverse cooled it is good

FWIW, having a lt4 intake and heads, doesnt magically change the motor into a lt4. Just like putting a ls6 intake on a ls1 doesnt make it a ls6. Go by whats cast on the block, it makes things alot easier.
Its not really that big of a deal anyway, is it?

It's funny they call the LT5 an LT motor when it's vastly different from an LT1/4. You can't even swap any internals from my understanding, so it's not like the LT4 is to the LT1, where you can just change the upper end.
Come to think of it, didn't the LT5 come FIRST?
