Default Re: 427 quadrajet selection

I need to add, after further research, that the compression test on the 427 may have been inaccurate, the engine was on a stand and hadn't been ran in a few days so it was cold at the time of the test. That being said, there was consistency with seven out of eight cylinders with one being considerably lower than the rest.

I would suggest two things...

First...confirm the engine compression problem one way or the other before going any further...all the other tuning and carb issues are academic if the motor is not ok.

Second...talk to Eric Jackson [Vintage Musclecar Parts] his ad is on the right...just give it a click. He can help answer your carb questions and point you in the right direction. Chevy used the QJ carb on everything from 305's to 454's...and lots of motors in between. Some of the later carbs may have more "smog" features built in...Eric can recommend the best way to go. His reputation and quality of service are well known on this site...

good luck with your project...post a few pics for the gang to see.
