ScottNM Posted May 27, 2011 Posted May 27, 2011 My 454/467 I am getting is rated at 517hp/564 torque. What is a good motor mount that is good for street? Do I need poly or is a standard metal mount OK. thanks Quote

That's about what hp I'm putting out and I'm using Energy Suspension poly mounts. I also switched my tranny mount out to poly. Seems pretty solid with little movement and no vibration transmitted that I can feel while in the car. Quote
72 LS5 Posted May 27, 2011 Posted May 27, 2011 I also used the Energy Suspension motor mounts. Bill - I used a poly trans mount on my 98 Trans Am and there was so much vibration, I had to buy a stock replacement. I wonder why there is no vibration on the Monte.... I'm wondering b/c my trans mount needs replacement. Quote
Ian Posted May 27, 2011 Posted May 27, 2011 It might be because the ends on the Monte cross member are set in rubber... Quote
71monteme Posted May 28, 2011 Posted May 28, 2011 i still run the stock rubber mounts, they lasted for 10 years and over a couple hundreds of mid to low 11 seconds 1/4 mile passes. but i'm going to go with the poly if/when the stocks one goes. thanh Quote

Actually I have removed my rubber pads on the ends (I needed that extra clearance) and still no vibration. Quote
Sam (Bones) Posted May 28, 2011 Posted May 28, 2011 the aftermarket mounts can/do vary in hieght which can change the driveshaft angle, some cars are more sensitive to this than others Quote
ScottNM Posted May 28, 2011 Author Posted May 28, 2011 the aftermarket mounts can/do vary in hieght which can change the driveshaft angle, some cars are more sensitive to this than others That is a good point. Maybe I should go oem. Quote
Heckeng Posted May 28, 2011 Posted May 28, 2011 I just installed solid mounts, and I am very happy with how little vibration there is. And, they were tons easier to install than the stock style because it is easier to get to the lower bolts. Quote
CrazyDavey Posted May 28, 2011 Posted May 28, 2011 I have solids in the Chevelle too and I really don't feel anything different. The Energy Suspension polys fit fine.... Quote
