aint that a waste of time wouldnt it be better to mod what you got or go for a 6 liter

everyone automatically jumps to a 6 liter.

with the right setup, you could make any motor run fast.. its just obtaining the right combination.

well i said mod what you got rather than try to put 5.3 parts in it...you are only gonna gain a few extra ponies for a lot of work.....im a 4.8 fan

You need to know the compression height if the pistons to know if its possible. Also the deck height. The comp. height is the distance between the top of the piston and the center of the hole where the pistion pin goes in. Common sense tells me that the dished 5.3 piston will have a bigger comp. height, but you never know.

Here's the formula

(1/2 stroke) + (rod length) + (compression height) < or = deck height

I guess it could be > than the deck height, but not by much!

I would try to use the longer 4.8 rod with a custom piston, in order to yield a better rod to stroke ratio, which allows the pistion to dwell a TDC longer and it slows it down. Nitrous would like that!

I don't think you could get the longer stroke of the 5.3 crank and the longer rods of the 4.8 to work. You wouldn't have enough room in the piston for the pin.
