Answer 1

first the link you gave gave me nothing second it can be to much gas for a stock motor if you want to up one thing you need to up the cam and exhaust and the key word is to balance you need a cam and heads to mach the intake and carb you run then it will have to breath so the you need to modify the exhaust to headers and then if you get a little radical about it then you may need to put a stall converter and a shift kit in the trans
