5.3 liter bored= 5.7 ls1 style iron block?? Is it possible to have a budget build up using a 5.3 liter motor and do the following? Thus making it a 5.7 liter iron block? Any benefits? Will it make just as much power with bolt ons as a LS1? or less? can it handle more nitrous?
What are the pros and cons of doing this? Becuase this setup can be put together for pretty cheap... just need your opinons

I don't see how that would be cheaper than just buying an LS1 block, but assuming you could, these are the pros and cons as I see them-
Bore/stroke ratio has something to do with the performance of an engine. longer stroke makes more torque but doesn't rev as high. Bigger bore is generally better for making power than longer stroke, because you make displacement, and don't lose the ability to rev high.
Traditionally knowledge says Aluminum blocks are weaker than Iron, so your iron LS1 will be heavier, but I'd guess it would also handle more nitrous. The block itself would anyway. But putting the LS1 pistons in an iron block won't help. The LS1 pistons are considered a weak part of the alum block, putting that same weak part in an iron block doesn't mean the pistons will now withstand more nitrous. If you put the pistons in the iron block you're essentially upgrading the strong link in your chain. The weak link is still gonna snap. Our stock rods are also pretty weak from what I've gathered.
It sounds like an interesting set-up if you put it together well and really thought about it. But these cars have been around for awhile, and theres a very active aftermarket. If it hasn't been done yet, theres probably a reason.
my $.02

Once its bored to the 3.90 eetc bore there are several stroker options all depending on what stroke you go with on the crank...Yes it can be done...Yes I like the idea for a small budget big power combo.
