Timing advance barely moving
I finally got the car on the road tonight for a test drive, The engine really has no power, and the advance on the crank pulley only moves about 5 degree's.
The engine will idle, and will start up easy. I am running KRE Aluminum heads, and a Crower 60919 Hyd. cam. The motor was completey taken apart to resleave a cylinder, and I had the machine shop, reinstall the cam and crank. The cam was set to a 108 degree centerline, per Jeff Kaufmann, Crower say's 109, but I listened to the Pontiac engine guru. I had some trouble getting the lash correct, but the rattling from the rockers has pretty muched stopped....1/3 lash at this point. With more lash it rattled alot more and at 3/4 lash the engine rocked harshly in the engine bay. So I backed it off.
Any idea's?
Cam installed wrong?
Timing gears off......Timing set at 15 degree initial, 15 degree bushing, where it was last year and really liked it with the big heads.
MSD digital, blaster coil, Msd dizzy, with the vac. advance plugged off.
Any suggestions as to narrow down what is wrong? I have a good balancer with all the timing marks and it only went on one way. Lash way off? I triple checked it also....I am just learning as I go.
