New issues - Help !!

Edit: ---> Solved-----> Swervin Ervin--> is the winner !!!!

Thanks Swervin !!

Changed out the ditributor, and shazammmmm....
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.

NV,

I don't know anything about your engine, so forgive me if I'm bringing up things you've already checked. It really sounds, as if you have timing issues or a vacuum leak. Have you checked that TDC on the balancer really corresponds to TDC on #1?

Sounds like my problem I had when I got mine started the first time as well. I was a tooth off on the dist. Check to make sure that you are dead on and retry. Also check for vacuum leaks.

Other than Brian's suggestions, I only wanted to add I don't care for Summit's distributors. I bought one before I got the MSD. I sent it back real quick. The one I got was junk. I never could get my engine to run right with it.

When you mentioned the Summit distributor, a light came on. Although mighty dim, it still came on.

I remember the trouble I had with the one I bought. I tried everything I could to make it work. Something was wrong with the Taiwan made piece of crap. I wasn't going to buy a new distributor and start replacing stuff on it. I also wasn't going to risk sending it back for another one. This is when I bit the bullet and bought the MSD Pro-billet HEI and never looked back.

Glad you found the problem and I was able to help. At least I can still win some things.
