Fires up like a race car and kicks ass..


------------------------------------------------------------------------------
Got my engine broke in , but it's got issues

Specs:

Edelbrock 1406 600 CFM -Carb
Summit HEI High performance Distributor
Power+Plus Polished Manifold
Competition Cams 327 - 350 HP Cam
Duration .280-.280 / Lift .480 /.480 Lobe separation: 112
(I will double check the cam specs, but should be right.)

I am putting all I can think of or done;

1. Timing is jumping between 8-10 degrees

2. Vacuum is weak

3. Hard to start (valves are set right-)
--> will back fire through carb (catches fire sometimes)
--> have to advance dist higher to start

4. At idle guessing 800-900 rpm, when I put in gear - it dies.
Idle is good and runs on it's own otherwise.
