Hey, im 15 and i gotta 87 z28, its got a pretty much stock 305, i just put high performance wires and plugs on it, and high output moduel and rotorcap. I sold my dirtbike for 750$ and now i need some tips to get more hp with hurting my lowerend. so if you couldgive mesome tipsto do to my 305 foraround 700$ that would be GREAT.

thanks, Cole M

 

my nephew is in the same position as you are. he has an 88 formula. your z28 probally has 2.73 gears in the rear end if it is an automatic. i would use the money to put 3.55 or 3.73's in. it will give you the biggest seat of the pants increase. after that, i would put an exhaust. putting a 350 in place of the 305 will be a cheaper increase for power than trying to get more power out of the 305. You will probally only be able to get the gears for $750, but now you know what you have to save money for.
