Hey guys I’m looking for some motor mounts for my dart. I need something better then the ones I can get on rock auto. Maybe something polyurethane? I just had a 360 built and want something strong. Any recommendations??

In my experience, anything under 400 is fine with biscuit mounts, they are on ebay NOS and repros. If you are seriously worried about the motor twisting, torque strap the mill and you will be fine. Or go with solids. You could always look for a 73+ kmember and go with spool mounts too.
 
The fun is feeling every ounce of HP and hanging on :steering:

If your women like Harley's they will luv the car!!:lol:

Thanks for the tip. It’s a 67 dart with a k member from a 72 dart. I might just find some new mounts and try them. The ones I got for the 318 that’s in the car now are very soft. The motor shakes a lot from it being so soft
 
I had some biscuits from a teener a-100. They were considerably thicker, but may give you a little more stability. Don’t take as gospel cause I’m speculating. Probably raise motor by 1/2” compared to most passenger car ones I’ve seen. But I’m going to go as far as saying you’re not going to start breaking stuff until you hook. In the meantime, I found these

Mid eighties truck mounts. Overlapping tabs keep them from pulling apart, won't need a torque strap. Rubber biscuit keeps the fillings in your teeth. A little thicker than standard biscuit mount, but that can be a plus if you have to shim your mounts for header clearance. $3.60 a pop for good Anchor brand on Rock Auto.

I used the poly interlocked mounts, so far no issues with them, 408 560hp.
 
I was tearing mounts because I was using my old spares (old rubber). Once I bought New stock style I never had an issue. You can always add a chain or cable just in case it breaks but I don't think you'll have any issues.

good for 4-speed with steel bellhousing. could also use regular mount on passenger side with steel on drivers. adding 73 and up trans mount and crossmember would give a little flex. I don't think solid mounts with an automatic "were" recommended...unless the 73 and up trans mount/cm combo is used. I used the steel mounts on a 340 4-speed car that was mostly street driven with no problem, never worried about mounts breaking when side stepping the clutch,er,i mean my foot slipping off the pedal.
 
ran solids with my balanced 451/727 combo. Not harsh at all. Could feel the motor but it was just a massage chair. Just barely, like a manual transmission with your hand on the stick. The truck mounts are a good option if you got the room.
 
I didn't care for the vibration with the solid mounts with my 340 4 spd. steel housing but that's just me. I should have tried just keeping the left one in . I use stock with a chain bolted to the LH motor mount bracket to k member. You could buy this as well.

P.S.- These also happen to be the same thickness as stock mounts for early A's (up to '66).
