ok, i bought the car for 4500. it has eld headers and pos trackion. it is a 91 z28 the pre owner said it has a 350 but stickers read 305 tpi. 350 would pull harder! the speedomiter does not work until driving for 25 mins in car. the car does not shift correctly because i belive pre owner changed rear end diff to a drag race gear. IT is shift with a b&m shiftter with 1,2,3, and D, but does not shift into overdrive. it is a rabbit car and will take ofF strong for 0-60 after that it gets it *** kicked. i want taller gears and want to keep the orginal enigne but upgrade this 305 with a stronger bottom end and top end to the motor. ANY SUGGESTIONS ON GEARING THE REAR END OR TRANS, AND KEEPING THE ORGINAL COMPUTER IN THE CAR AND POWERING UP THIS ***** 305 240 HORSE MAYBE MOTOR. I REALLY DON'T WANT TO SWAP MOTORS, FUEL INJECTORS, COMPUTERS, AND CHANGE ALL EVERYTHING, OR I WOULD CUT OUT THE COMPUTER AND RUN A CARBERATORED MOTOR BUT I WANT FUEL INJECTED ONRGINAL CAR.

 

Wow

 

Dont waste youre time sell the car seriously.
Youre looking for something that isnt there and you are going to have to change a LOT to make everything work properly. It costs money lots of it.

Modding cars is a slippery slope takes $ time frustration doing things twice etc etc. I dont think youre ready for it yet. Just being honest from reading your post.

 

Amen to that! been there done that got the tshirt, 3 times. I wish I left my monte stock, and learning that lesson so many times over is what stops me from touching my 2010.

 

Based on what you DONT want to do, sell the car and get something else.
