I have a 1991 camaro that did have a 305 in it throttle body. Replaced motor with a ZZ3... with edelbrock carburetor... 600 electric.... car ran great for 2 days... like it idled fine took off fine did everything great i was so happy because my car had been sittin for the last 2 years so to have it workin great was awesome ....

but then i was driving it the 2nd day and turned it off went in my house came out started it up started going down the road about 40 mph.. i was easin into the gas and the car just had no response... tach went all haywire and the car bogged out and died... it starts up again everytime but then bogs out and dies...wont stay and idle.... maybe for just a bit but dies....

Im open to any idea or suggestion so POST THEM all i'll be sure to look into all plausible ideas... thx guys... later

 

Did you tighten the dizzy bolt? It could have spun on you...

Other than that i would say pull the coil and module from the dizzy and have them tested and/or replaced.
