Would I have to Bore out an LS1 to make it a 408 Stroker?

So with this kits http://competitionproducts.com/products.asp?dept=817, are your basically putting in a new engine? Or are you just adding the internals to be a stroker?
It looks as if they are selling complete shortblocks and that is an easy way for you to go if you did not want to do much assembly work yourself. You have to ask yourself what are you comfortable doing? The more you can do yourself, the more you will save.

My advice is, don't use a Darton sleeve kit. A good 408 will be built from an iron block LS engine. The blocks don't cost much. You cannot make this from a used aluminum engine, although you can from a used GM truck engine (it its the right casting) - you can bore out iron, but not aluminum.

Iron block, (new) don't cost much, and are bulletproof.

Sure you can do the 408 with an iron block and it is fairly inexpensive to do so but what is wrong with the Darton Sleeves?
