I had 300 lbs springs on the front coilovers but with an iron block and a 60 lbs turbo, i need another spring because my 300 pounders are almost maxed out on height. Does that sound right? if so should i step up to a 325 or 350 lbs spring?

It depends.
How much are you wanting to raise it up, and how much adjustment do you have left until it is safely maxed out ...?

I normally recommend 325's to iron block turbo guys. But it also depends on if it's a full weight/street car or a lightweight track car. If you are almost maxed out on height adjustment on the 300's, ten it sounds like you may need to step up to the 325's.

Its pretty close to being coil bound, not really close but close. So 325 will be enough or will 350 be better? its a street car with the battery in the back, and no ac with a cage.

IMO, since you said you almost maxed on height adjustment an it a street car, I'd go with the 350's then .
BTW do you springs show visual signs of ever being in coil bind...?
