anyone break motormounts?

my 302 roller is finally here! it is going in very soon. my engine was dyno'd at 406 horsepower out of the car. as in, with no transmission or car. i still have my original diff with 1 wheel drive. i am wondering if anyone else out there in the 350 - 400 hp range has broken motor mounts. i have been trying to find aftermarket performance mounts and ...... well you know the story. I am not the most aggressive driver, but i do like a good smoke show now and then. let me know what your experience is. thank you.

 

I have broken the left mount with less than 400 HP on tap...heck less than 350HP.
You may want to consider a torque strap set up of some sort.Or solid mounts(not fun in a street car)

 

I've heard drilling a hole through the mount and putting a bolt through it works well. Never done it myself though.

 

I use a turnbuckle from a hole in the frame up to a hole in the head. Then just tighten it up.

 

Here is how pinned my mounts in my Falcon. I don't have a V8 Maverick mount in my hand to look at but I'm think the same thing could be done. http://1bad6t.com/motormounts.html

 

I broke a motor mount in mine and its nowhere near 400 hp more like 250-275 hp

 

the new replacement ones i bought at the local Advance were made like that
