I have been reading posts/reviews both good and bad about Gronk Performance. I have tried his website with no luck. Seems like he has steadily been going downhill for quite some time now. I would really like to make the 2100-2150 conversion and get rid of all the clutter of vacuum lines and associated things. Can someone tell me if he is still in business? ...
You could check ebay for his products.
I got one of his offshore 2150 & adapter. I specified: new not reman, AMC Eagle 258 with 4.0 head, choke combo of electric & hot air (HX inline with the coolant out of the intake manifold), focus reliability & fuel economy. Worked out of the box without adjustment, except for bending the bracket to adjust the throttle spring tension, and adjusting the 'kick-down' so the trany isn't trashed. I did have a chore tracing down all of the vac sources to either use or cap. Others have had to rebuild theirs. This appears to be a YRMV. I'd recommend the 2150 over 2100, just so it's something slightly more 'modern'.

He's still listing on ebay. Kit with carb, or adapter kit (studs & gaskets).

Don't be so quick to get rid of the vac stuff. First understand what each does and brings to the table, then pick and choose. Emissions requirements in your area are a factor too.

Once you're back, you'd be surprised how much you can do yourself.

My last post on this topic.

Just wanted to let everyone know they just pulled into the driveway. From Page, AZ to Amarillo in one day. Then from Amarillo to Copperas Cove today.

Thanks again for all the advice and tips and help.

Thank you.

Doing a ECM Test bypass and a proper 2150 motorcraft carb would help. That will give you the chance to remove a bunch of problem vacuum parts. Only reason I would say avoid the Gronk upgrade ( I have one ) is the carburetor is a Chinese made copy. If you can find a original either in a junk yard or on evil bay I think you would be better off.
Even with my gronk carb and a ECM Test bypass mine ran better. I think the ethanol fuel is a problem. I also did a hei upgrade, used the gym style with the coil in cap and the controller built into the base.
Another problem is the electrical, bad connections wrapped in duct tape and over wrapped in electrical tape.
I spent most of the winter cleaning that up and installing the hei.
