if ya wanna get rid of the engine i no someone that might want it lol. how much do you wanna spend on it? you can get quite good power out through the standard carb so the efi system should be fine if you dont plan to soend to much.

as for the twin forties, they work fine up2 a certain limit in power then 45s are much more free flowing for the engine and 48s only realy used by proprer racers if ya get me ( wont get a great gain over the 45s )

cam again depeneds on exactly what you want from the car ie, just track days, road use, abit of both, or weather you want low end or top end power. personaly as a rule i would change the oil pump and spray bar no matter what the milage is on the engine and regardless if it has bee done before.

if you are keeping it N/A then a rebore to a 2.1 is a good cheap idea. uses machined pistons from a v6 and a 2.something overbore, shud be ok if it is a 205 block.

skimming the head will rais compression which again depened on the age of the enigne " can" be a good idea.

lots of depending factors mainly money
