i have recently applied the open air element, edelbrock performer tbi intake, ultimate tbi mods, lightweight drive shaft, borg warner 9bolt posi 3.27s. Also running an open high flow cat at 6degrees advanced timing. the engine has 175k with a full tune up.
now the question is are these good mods for the 305?
also does anyone know what hp/tq/et difference the engine would have?
is there anything else that would greaty compliment these mods?
thanks

 

230/330/14.5?
thats my best bet

those are excellent mods to start with, but too add to that, most people would suggest getting nitrous, i also recommend a new cam, new heads, and maybe a new full exhuast.

 

i doubt he is near 230/330 with that car.... you need a full exhaust headers all the way to the bumper as no matter how much air the engine can get it will still have to force it through the punney little stock pipes

 

Should be a mid to high 15sec car.

 

my bad, thats what i was suggesting, if he got the stuff i mentioned it would get that much if not more

 

possibly but not with his stock cam in there in which would require some tuning to the ecm and it doesnt sound like he is ready for that
