It looks like the 5.3 stroker kit is not very common, I'd like to know more too.

 

the economics are a little skewed, too, because an Fe 5.3 is only worth $400 or so these days and the stroker kit's going to be in the $1000s by the time you're done.

We're boosting a 5.3 in the shop right now with the 317 heads and LS1 intake to clear the hood. we think it's a cheaper way to get to 500HP.

 

Based on what your after and what you have to work with, you should copy the iron 5.7 I had built for my truck. I'm not trying to push my ad in the classifieds, but if you want details on it..............look there.

 

thanks guys, im still new at this sort of thing so all help is appreciated

 

I believe a 4.8 or 5.3 block can handle a LS1 383 stroker kit, but I could be wrong.
