Well guy's I dove in and tore it apart tonight and what I found is in the picture below, on the left is the edelbrock timing set that was in the car and on the right is a spare set that I had kicking around the shop, Anyone notice a difference? the edelbrock set has keyways on the crank sprocket that appear to be 45 degrees out compared to the set on the right this corresponds with what I noticed when I was playing around with my dial gauge before pulling it all apart, All the valve events seemed to be 45 degrees out. So the question is how is this possible? the crank sprocket fits on the crank perfectly(like it was made for a pontiac) So what is this thing actually meant for? Tommorow I'll install the spare set and hopefuly everything will work out.
