Ram Air for 351 4V
#1
Hello Fellow Enthusiasts; Would like to add Ram Air to my 1973 CJ Mach 1. Since Ram Air was only available on 351 2V engines, does this mean the 2V ram air cleaner will NOT fit the 4 barrel carb on the 351 4V motor?!....Has anyone adapted Ram Air on their 1973 Mach 1 CJ?!, and if so, will you Please share your experience/s?!....Thanks!!!...Mark

From what i know...The 2v ram air will not work on the 4v...I think the 2v ram air cleaner is too small "that is i think"...lol...I know plenty of 73 owners just put on 71-72 ram air set ups on there 73..Same carb on 1973 cj as previous cobrajets...Even boss has the same carb...4300D....No issues that i know of putting a ram air from 71-72 mustangs on a 73 mustang....Only big issues i hear about is use of taller aftermarket manifolds.

There is no 71-2 VS 73 ram air set up
There is small block 351 and big block 429 set ups

The base hole size for all 302 - 351 2 v , 4v 's and 429's were the same
It is a pretty standard size - that is why the after market chrome air cleaner fits almost everything

If it is a stock carb and intake it will probably drop right on
If you still have the EGR plate you may have to remove it.

I have a repro kit for 529.95 or some original set ups too
The originals are just a bit more money Tongue

The reason the 73 351C 4V didn't come with ram air is because that year used an EGR plate for emissions making the carb too high to use ram air. You'll need to remove the EGR plate if its installed. I you dont the hood won't close. You can swap in an Edelbrock Performer while you're at it for a couple hp.

Hello Leon; Please correct me if I'm wrong....But didn't the 1973 Mach 1 351 2V Ram Air car have the EGR plate?. That didn't have obviously a "Hood Closing" problem.....Mark

Nope. The 2V was a non performance engine and didn't require EGR thus no plate.

Yeah, ford two barrels, unlike mopar and gm, use the same size air horn and air cleaner as the four barrels.
