1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub
Sigh, so there is still an issue. I'm not sure if this one has been since start up or happened after. I didnt do a compression test before startup because I was excited. Never again. The car pulls pretty good now but there is still some blow by. Finally got around to a compression test and cylinder 7 and 5 are 80psi >.< the rest are 180. Machine shop had put the bottom end together again. And the shop is very reputable and have built motors for me before that get their *** whooped with no issues, so its not something they're doing.
This time I had a tune in the car from the sloppy tune cabinet and timing was way conservative at like 12 degrees. BUT a friend from sloppy did notice something. I'm running the round 585 coils and apparently their dwell time is supposed to be 4.2ms max. And holley defaults to 4.5ms. That can cause all sorts of hell with advancing the timing a ton on its own. Idk if that has been my issue all along but we changed that last night. Hopefully gonna have the motor back apart this weekend and see what happened.
On the bright side, I did get it aligned. And the engine bay looks pretty awesome lol.
