Welcome to CHR Geo!

We’re a pretty knowledgeable bunch but I’ll be darn if we’re not fresh out of crystal balls.

Could you give us a little bit more info like?
1. What engine
2. What car
3. We know it’s an automatic, but is it TH350/400 etc.
4. You replaced cam and lifters and timing set – did you use stock components
5. Where are you timing the engine? If it’s a stock 350 Chevy, I start with 8 degrees and work from there with all vacuum disconnected.
6. Do you have a stock ignition?
7. What is your idle speed?
8. Is this an Edelbrock 1406? Great unit but tend to be rich out of the box and on a stock engine might need to tune a bit.

Others will chime in I’m sure. Once again welcome and get us some more specific details and we’ll see what we can do to help you out.

Regards,
Glenn
