i am trying to switch my six cyl to a 302 in my 66 f100 im told the perches will not work will the perches work from a early 70s bronco with a 302 or can i shorten up the six pearches
thanx paul

 

Paul, There are only 2 perches not 6, afaik. When looking at them the 302 perches angle back towards the firewall where as the I-6-FE perches are more straight out. I think I read that the 400 M uses them also, so there could be more choices.

I believe you will have to look in 68-79 trucks for them, but can not advise on the bronco.

Bronco perches do not work.

you need small block 302 perches or 351M 400 perches form any 69 to 79 ford truck.

The 300 perches work but place the engine too high in the chassis. And create drive line issues along with exhaust clearance issues.

 

thanx guys i found a set out of a 1975 f100

thanx paul

 

Paul that has been covered several times but I don't remember if you drill another hole or move the perches to another set of holes.

Use the search feature and see what pops.

When I converted from a 300 to a 302; using the perches that came from a 66 model F100 with a 76 model 302 as a donor truck I use; I had to move the perches back to the last upper holes, I believe and one lower hole line up, it was the front lower one that line up. I then drill the lower rear hole to fit. The only issue after doing this was my oil drain plug was too close to the crossover frame mount; for which leaving my perches in the holes I mention , cause me to have too drill a 1 1/2" hole into the crossmember to allow me to unscrew the drain plug completely to change my oil. also my C-6 seem very tight to install as well; but was able to do so.
