Hello Jim, I have to ask why would you consider removing the crossfire setup? Troubles with drivability? Looking for a little more umph under the hood?
Edelbrock has their 4 Gen Pro Flo system out now. Improved and self learning. That is a multiport injection system.
Holley Sniper EFI is a good one too. They just released a Q-jet version of their throttle body.
Then there is the option of having the stock throttle bodies reworked and bored out along with a Renegade intake mainfold that it a direct performance upgrade for the '82-'84 crossfire engines.
I hope your travels went ok. Sorry I didn't get back to you, a few things came up and I completely got sidetracked. My apologies. Oh and I did talk with old Ken a couple weeks ago. We had a nice long conversation. It was good to talk to him. I let like 2 years slip by. I guess I'm really bad with time management. yikes!
