Street & Performance (S&P) Motor Plate Question
Has anyone used the S&P motor plates for an LS install? I tried them today and they were not even close to fitting properly! We have a 6.0L from a 2003 SS, the plates from S&P and OEM motor mounts! No Luck! Any ideas???

Re: Street & Performance (S&P) Motor Plate Question
Could you share more details about why they didn't work? Did you use the one's that locate the engine in the same position as a sbc or 1" back (seems I remember S&P offering both)?

SCOTI
Could you share more details about why they didn't work? Did you use the one's that locate the engine in the same position as a sbc or 1" back (seems I remember S&P offering both)? Gladly SCOTI, We were to test fit the engine and transmission today but were not able to get the engine to fit. As the motor was being lowered, I noticed severe clearance issues with the crossmember. As per S&P instructions, the plates with the motor mounts attached were bolted to the sides of the block. We were unable to lower the motor any further once one of the "ears" on the block, just above the oil pan, contacted the crossmember. At that point, the S&P plates with the motor mounts were still 4 inches away from seating in the correct position. When I looked at the engine head-on for perspective, it was evident that even if the block had cleared, there were two reasons why the plates would not work. Firstly, the angle that plates sit are not close to matching the angle of the crossmember mounting location. Secondly, the distance between mounting points was two and change inches wider on the motor than the crossmember. Therefore, with the width discrepancy, only one mount would seat properly and the other would be outboard of where it should be putting that mount on top and away from the mounting point. That obviously would not work... I can't understand why S&P would deliver a product like this that is so obviously incorrect... |

Re: Street & Performance (S&P) Motor Plate Question
Hi,
I have a LS-7 in my 67. My motor plates are from S&P and all I had to do to make it fit was elongate the holes on the stands about an 1/8th inch. I used a trans mount for the six speed from ECE. Are you sure your engine stands are from a 8 or purhaps a 6 cylinder?? The oil pan is usually the stumbling block, have never heard of the mounts being a problem. Mark from S&P will gladly help with your problem. Any questions send me a private message Rob |
