The biggest issue with LT1 cars (1993-1997) is the Optispark distributor. I would recommend buying only a AC Delco distributor if you need to replace it. The LT1 cars use reverse cooling, no issue with overheating that I have seen. If a car runs hot, I would check to see if the cooling system has been properly flushed and maintained. Good luck! |
Make sure the air dam is still in place under the front of car, people tend to hit them on parking stops, and rip them off, or remove them if they're hanging by a thread. If the front air dam is missing it will overheat.

I used an Optispark from AIP Electronics. They are pretty inexpensive but they are made in China so quality could be hit and miss. However, many have been happy with them including those with C4 Corvettes. There is also a guy that rebuilds them and he has extra Mitsubishi sensors that he uses in the rebuilds. He goes by the name of Optidoctor on the 4th gen forums.
He can be found on Ebay: https://www.ebay.com/str/optidoctor Also reference this: https://ls1tech.com/forums/lt1-lt4-m...ble-today.html |

I know that some people replace the Opti distributor with a coil on plug set up like the LS1 has. |

Also, for a 93 you will be running speed-density (no MAF sensor) and can only reprogram by replacing the chip. 1994 and later are EEPROMs and can be reprogrammed from a box (Hypertech/etc) or laptop. Big advantage if you are planning on doing significant mods to airflow/power. I've replaced the function of the opti (still uses wheel and sensor for just crank position) but it really is a pain. Unless you go to the "full front LS1" conversion with LS1 computer you will be working with the classic LT1 computer and a Dynaspark to go to multi-coil but even then its 4 coils for 8 cylinders, not full coil-on-plug like LS engines. |
