I went fron 302 with C4auto to 351 with a Tremec TKO600 5 Spd. Just tried to start it up today and it started cranking when i turned the key to the acessory power. Tried switchin some wires around on solenoid but couldnt figure it out. I did have the whole dash out also. Any ideas?
Wow you must be new to this stuff. You only change one thing at a time on an old car, even when you know what the h**l you're doing.
Too late now. You're in for a lot of troubleshooting.
