I'm looking for some advice. I currently own a 1988 Chevy Iroc-Z convertible with a 305 TPI. However the motor is on its last leg due to the following mods: 100 NOS, Paxton Supercharger and all the available bolt on mods without having to remove the heads from the 52mm Throttle Body to the Flowmaster Exhaust. The car still runs strong in the 1/4 averaging times around 12.8's squeezing into second gear without slicks. Although one major problem is when the car is parked for at least a couple of hours when I return and start it up it blows white smoke. I'm not quite sure what the problem is. But it doesn't appear to burn oil. I'm interested in replacing the motor with a 350HO. Unfortunately due to my recent layoff from my job my budget is tight. I originally wanted a ZZ4 or LT1. What would you recommend. All feedback is welcome. Thanks in advance. Also if anyone is located in the Southern California and is willing to help (willing to pay) please let me know.
My 305 tpi always gives a little "puff" of blue smoke if i havent used the car in a couple of days, i dont think thats something bad what do you think?
Not necessary to replace the Heads for the installation of Valve seals. Depends on your mechanical skills to replace them and it may not be your DIY type of job.
