Currently finishing up my 90 formula started as a 305 tpi I had a bbody lt1 with 60K so I thought why not.I didn't want to deal with new wiring harness so I'm retuning the prom and using the tpi harness putting a distributor in and getting rid of the redheaded optispark stepchild so be done in the next couple off weeks using a a/c delete,bbody p/s lines and making AN fuel lines
