89 tpi 5.oL computer to 87 5.7 tpi
what are the computer differences between a 89 305 tpi computer vs a 87 5.7 tpi motor with a 9th injector. Im trying to leave my 305 together for another project. Are the computers the same with differnt chips? thanks

so will i need a custom chip for my car to run the 5.7? I have the original computer out of 5.7 car. And should I look for an intake without the 9th injector?...I live in FL thanks

same 1227165 ecms but the calibrations in the memcals are different. You can use any 86-89 350 programing but some 88-89 have vats enabled. The 89 programing will get rid of the need for the ninth injector. Hawksthirdgen has the block off kit to delete the ninth injector.
