I would be cautious if the car has Borgeson steering on it now or if its planned for the future.  My JBAs, while nice headers, hit the box hard on my '67, and required a pretty good sized dent to clear.  A 351 might be a different story though because the engine is taller than a 302/289.  This could move the header up enough to avoid the interference, but if a Borgeson box is in the car now or in the plans for the future I would ask someone who knows that specific question. 

In general I will say the quality of the JBAs is first rate.  I liked the ones on my '67 so much I bought a set of my '89 GT too. 

Not sure what part number mine are, but they are designed for cable clutch. I do not have steering box, so clearance is no issue.

I have the JBA shorties in my 68 with the 351W. 67-68 engine bays are the same and I also have the Borgeson steering box in mine. I have no clearance problems with the headers or the Borgeson box. The only issue I had with the JBA installation on the 351W was that I had to cut off a small 1/2" protrusion on the block at the forward end on the driver's side to get enough clearance for the tube on the #5 cylinder exhaust. My block was from a 1976 Torino. I also have GT40 cylinder heads from a 98 Explorer 5.0L, so maybe that contributed to the issue, or maybe not.

Oh yeah, I forgot, my left front header hits the block ledge also. My block is a 73 with Eldebrock Performer heads. I had to modify the header but it is right at the bend and was hard to persuade.

I was able to find a picture online of the JBA 1653 (351w).

Anyone running these with T5 bell housing (cable setup) and 351w?
To me this looks like a No-Go.
Running stock gear box too

Thanks for sharing information.
Looks like I will skip this option.

I had run across 1653 ( non cable) and at a great price.

Not giving up my cable clutch.

I have a pair for sale but they are not for fitment with cable clutch. Somebody with an automatic could get a good deal.

   Ill PM on those headers.
