Are these hookers too close...
. The car is a 1st Gen Fbody. The passenger side front header has maybe 2mm clearance (pic) to the upper A-arm. I'm using polyurethane mounts. Will the engine move enough during revving/acceleration to hit the A-arm? If you can get some more clearance and put a heat shield around the frame/suspension, that might be ok. but your still short on room.

As others have said I would use solid mounts and not look back.

too funny!
The mounts are short/wide 350 mounts; the headers are maybe 1/2" lower than the frame at the their lowest point..not bad at all. That being said, I wouldn't go with hooker headers again. The quality is a bit cheesy (ie cheap bolts, had to dent a couple tubes to make fit)
.
(1st gen camaro Part # 2288)1st set I received QUALITY was VERY POOR but since I had them did a test fit,clearance was good on both sides. Replacement set QUALITY VERY POOR fitment on this set VERY poor. hit p/s box / stater / and very close to controll arm. 3rd same as 2nd had to trim 1/4 off the controll arm end as it was very close same as posted pic and had use a hammer for steering box clearance. Next project I'll use another brand. HOOKER=
It made me sick to pound 4 dents on three tube of these brand new headers

It's hard to see on the pic, but the driver side has about 1/4" clearance around the steering box now.
I still don't get how some folks using ATS style mounts are getting away without beating their tubes like I did
To dimple the header. I would not directly hit on them, In the past, I have used a heavy hammer, but used a pipe or round steel rod, placed it where it is needed and then hit the rod/pipe. I made a cleaner dimple and didn't look as bad or I did any wild banging on the tube.
