LS motor installation kits

[LoRollr]

I called S&P today and they said i would need to buy a modified oilpan (don't have to with the BRP kit) and they don't make a bolt in crossmember for a t-56 in my car (BRP does). The spacing from the back of the engine to the firewall is about the same with both kits so i couldn't understand why I needed an oil pan for one and not the other. BRP told me that I had to lift the tunnel a little and I'm not sure if the S&P kit requires tunnel modification or not (forgot to ask). So I'm guessing that the engine sits lower with the S&P kit which causes the oil pan to hit the crossmember. BRP assured me that the pinion is in the acceptable range on their kit, so I think the BRP kit is the one for me.
