Bolt in solid motor mounts- any recommendations

[john@thepier]

I am putting a 408 stroker small block into my 70 swb. I will be building the motor over the next week or two. I am now just thinking I'll need to up grade the motor mnts. as well as all the other things. Anyone know of a bolt in style for our trucks? or will I need to engineer something my self. Thanks

Prothane makes a performance bolt in, part #7-509.

71 DRAGTRUCK have you had any experience with these? Estimated torque for my build up is 540 ft.lbs. They look like they should work nicely. Any venders on the board with these for sale. Thanks

I have a set ready to go in with my new motor, they look good and have a internal lock system so they can't pull apart. I'm going to use them on a 640hp. 620flb. BBC plus nitrous, so I sure hope they perform well.

you should use a solid trans mount also if you use solid motor mounts.

Not sure why you are going with solid mounts, if its going to be pretty much a drag truck only I could see it, but if it is more street I would look at poly mounts and use a chain or cable with a slight bit of tension on the drivers side, I have never broke a mount doing this and it works real well. Do not make the chain real tight or you will feel the engine vibration, just a very light tension so that when the engine starts to TQ it will tighten up.
