looking for any input any one has about what i want to do

so what i got to work with is a cast iron 5.3 block reason short on money and already have it, im wanting to bore it out to a 5.7 to start with and of course all forged internals.

and if i can maybe stroke it, still thinking about it, any suggestions?

then i wanna use a set of stock heads, well dont want to but most likely will cause of budget, help? which stock castings are good to use if i end up going this route?

im gonna get a good size cam, double springs, titanium retainers, and all the top end stuff

rockers is there any advantages to getting a set of 1.8 or will a good set of 1.7 be just as good?

thinking about a 100 shot of nitrous?

this is my first lsx build i have built plenty of old sbc but never a lsx
im pretty much lookin to get a nice reliable summer car/ track
not to worried about gas mileage or anything i use to drive a fully built 90s
383 sbc stoker
im hoping to get mid 400 range for hp
so any input is good thanks

 

come on someone has to have some info
