Off-Road Carb for an 85 CJ7 4.2

I am looking for a good off-road carb. It seems like I have narrowed it down to the Holley Truck Avenger 470 or the Motorcaft 2100. Most threads I have read about the Holley Truck Avenger are mostly about a 304 install. Has anyone put it on a 4.2?

Any thoughts about the Holley Truck Avenger 470 vs Motorcaft 2100?


Thanks,

What's wrong with the carter?

Or are you assuming its bad for off-roading because of all the crap on the Internet about how terrible they are.

I have the 470 TA on my 4.3 and I really like it. I am still having to dial it in but so far so good.

Did the previous owner throw the float bowl baffle in the garbage?

Look for a butterfly shaped baffle between the floats and the needle and seat.

After playing around with an old 1979 vintage MC2100 with 1.08 throat and installing a rebuild kit, I gave up and purchased a Weber 32/36 from Redline,4 years ago. Very happy. I installed another on my other 4.2 recently and happy there also.

Yes, I'm surprised he didn't look at the Weber 32 from Redline.
