Did you have to cut????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

FRENCHBLUE72 · 12-02-2005, 09:11 PM

I am installing some headders tonight and they are crashing into the motor mounts should I just cut the mount to clear???? I f you have ran into this problem what did you do to claerance it??? btw its a 454 on 350 stands 2wd 1/2ton

What headers did you use? I wouldn't cut any motor mounts, especially being a BB, lots of torque there.

**clay68c10** · 12-02-2005, 09:40 PM

The BB stands have an extra bend to clear the original manifolds. Maybe the SB stands are too tall? I had Hooker comps on my old 396 and they cleared the BB stands by about 1/2" in that bent area.

My bb mounts have a clearance curve right under where the mounts fit. Small block mounts don't....
i am not sure what company has them but there are tubular aftermarket mounts that are around 120 with mounts and they are suposed to clear just about anything.

we put a 454 in a 70 model with sb stands and the hedders hit the stands. had to change to bb stands and then everything fit ok

ratrod67 · 12-02-2005, 09:57 PM

Yep, you need BBC stands. I tried it on sbc stands and it didn't clear either. I went through 3 sets of headers even with the right BBC stands before I found a set that didn't hit either the frame, oilpan or motor mounts. 3rd set was the charm.

FRENCHBLUE72 · 12-02-2005, 09:59 PM

Here are a few pics...... Can anybody tell me what year these motor mounts are for?? Btw they are headman headders..

71Dragtruck · 12-02-2005, 10:34 PM

What they said, mine didn't work either had to get BB stands, the ones that you have off look like the ones you need, with the dip in them.

**kwmech** · 12-02-2005, 10:39 PM

When you install the correct stands the engine will be pushed back 1''. If you don't want to do that you will be drilling

71Dragtruck · 12-02-2005, 10:41 PM

I just had to notch the big hole a bit for mine, then used big thick washers from balancer bolts, you can also make some out of thick flat iron.

ratrod67 · 12-02-2005, 10:57 PM

Those your holding look like 68-71 mounts. The 72 mounts look like this:

Longhorn Man · 12-02-2005, 11:09 PM

the stand you were holding is the 68 - 71, the ones mounted are small block and then there's the 72 style ratrod posted.

FRENCHBLUE72 · 12-02-2005, 11:24 PM

68-71 Those Are The Ones That Have The Rubber Part That Is Hard To Find Correct????

ratrod67 · 12-02-2005, 11:29 PM
