Really hate to hear that. I'm glad you found something, just wish it had been something simple.

I missed the post about finding a bad cam lobe.

a lot of times a guy such as yourself does not post enough information on what you want out of your car and the combination you have put together. Also what you are willing to do to get where you want to be. You are drag racing one of the most popular cars people like to race, and like to go fast in, but your combination is not one for doing that.

It now sounds like the used motor you bought is not that you thought it was and has a bad cam plus what else. So i think you are at a point where you need to step back and see that you really want to do with your car, what you want it to run, and get some honest help with a combination to get you to where you can afford to go.

Just trying to save you the grief i went through in the beginning. It becomes no fun to waste good money after bad and never really enjoy your car. Just saying.

installed new cam and lifters. Took the car for a ride and around 3000 rpm it starts missing and backfiring.. I double checked the valve adjustment and test ran again the same problem??

Did you go back with the same cam? Did you check the obvious, plug wire order, look at the plugs to see if it's lean?

What did you find out on this?

Did you do a complete cam with lifters and springs? Did you do a compression check to check the rings, valves and head gaskets?
