you really made me feel happy because of your opinion
i think my bottom end needs a new set of piston rings , but the block is really healthy
my dynamic compression ratio will fall of because of the cam lobe , so i need a static CR close to 14:1 to keep the dynamic compression about 12:1
i founded speed pro -11cc pistons for about 300$ , does them have good quality ?
the water methanol can let me to use pump gas
You don't really need a big cam to make the power you're talking about anyway. I'd look for something in the mid-to-high 220's intake duration and mid-230s exhaust on a tight 108-110 LSA, with lift in the upper 500s on both sides. Such a cam would be happy paired with a static compression ratio in the 11.0-11.8 range, which is all I'd dare on questionable quality fuel, even with something like meth injection.
As far as pistons, I'd go with something like a Mahle powerpack. The Speed Pro pistons are generally heavy; you don't want to go with anything heavier than a stock piston. The stock pistons weigh 532 grams, by the way. The Mahle Powerpacks are somewhere in the range of 460 grams if I remember correctly.
What sort of resources are available to you in Persia with regards to machine work and tuning?

The Persian people are not at all what our leaders or theirs make them out to be. The unpleasantness is almost entirely political in nature, because the USA has persecuted Iran through sanctions and general isolation ever since the regime we preferred was ousted in '79 was ousted. Folks in Washington still can't get over it because Iran is in a strategic location and has a lot of oil pipelines and trade routes running through it, which our oil companies and the politicians who serve them naturally want control of.

is this converter ok ?
FTI Performance ESR Series Torque Converters ESRL8082
http://www.summitracing.com/int/part...8082/overview/
it's almost safe here but no one is happy 
if i put a 4k stall converter , i wont need low and midrange anymore !
after 1-2 shift , the rpm stays about 4300 and 2-3 stays about 4800 , so i need a better 4k-8k rpm range i think
i have to buy the cam and valve train parts anyway, so why not to go with a bigger one? if i can make more power with a bigger cam , what is the problem?
i'm searching for the parts in summitracing , but there is not any mahle piston for sbc gen I - gen II for stock 4.0 bore ... any other suggest for a website to buy parts?
machine works is ok here , but no one knows about tuning !
one other thing i wanna ask is that why not to go with 1.7 rocker ratio?
i'm afraid of this 4600 elevation ... that's why i want to go with a bigger lift and duration , am i wrong ?
really good knowledge !
thanks for your helping

the power can be soft in the low and midrange

Don't mind Jersey Shore. They are all angry by default.
