i dont know about actual kW output increase, but it will be noticable - i went to willowbank drags on wed night with a guy from work, he has a '80 (or therabouts) cortina, 4 speed manual, open 3.25 diff and a 250 crossflow
it has a holley 465 carby and a torker intake manifold, full head porting and a 'towing' cam, double valve springs, stock rockers and pushrods, with 14 degrees of timing running on optimax.
the engine used to be running LPG in his dads wagon for the last 4 years, so it isnt a spring chicken.
with no tuning whatsoever it did a 14.88 second quarter at 149km/h
he only got one decent run (the previous two he accidentally did with 5 degreees advance, then with 0 degrees advance because he was adjusting the dizy the wrong way - silly - and did a 15.8 then a 16 flat...) so with some practice, an LSD and a bit of tuning a 14.5 easy will be the go! then a proper cam (for hp, not lb/ft) will go lower....
your car might not be as fast as it is heavier, but if it all gets tuned right it will give a lot of cars a damn good run!
just make sure the mods compliement each other - no good getting a massive race cam and roller rockers of you only do a very mild port on the head - port the head as much as possible, then get a cam to suit the airflow the head shop can achieve, and then get an intake manifold and carby to suit that.
and make sure you take it down the strip after you know how to drive it, and tell us all how you did - im betting you will do lots better than i did
