91 Vette with LSx idle video's at long last Finally got around to uploading my videos.
I can say with certainty that big cams (a comp 232/238 on a 114) and an automatic with a 3200+ stall sucks to tune. Idle has been hellish and I'm not 100% yet. The car does idle now... but I still have some issues with startup learning and transition to idle from high rpm. Just needs more tuning. When I drove it previously I should have said I babied it around for a while being very gentle so as not to upset it.
I've got videos uploaded...
With the first LOUD (dual 3's into 5 inch oval back into dual 3's) exhaust:

Then with the revised exhaust. Basically, I cut out most of the oval pipe and merged the dual 3s into a 3 inch center with a 3x18 bullet muffler and then separated back to dual 3's into Edelbrock RPM mufflers. Still loud... but tolerable:

Still no RPM tach or coolant gauges in the car... but I'll get there. First things first. Next is a getting some new fan relays... seems my 1991 vintage relays are dying and sticking intermittently. Can't trust em to drive!
