302/350 mounts are the worst if you are trying to gain clearance. They put the engine the lowest in the chassis. 307/327 mounts will gain you 3/8 up clearance. Moroso makes motor mount shims...not sure if they will work on a ls.http://moroso.com/catalog/categorydi...?catcode=28100

Use the stock GM gaskets. :yes:

Nice job gaining the clearance. :thumbsup:

I Used the same mounts you did but I think the difference is you did not use a stock steering box. The 307 mounts are higher on the passenger side but they tilt the motor over to much to the driver side. Buy using the 302 mounts I was able to get the motor level again and picked up the clearence I needed. I also used the 302 engine mounts which are much thicker buy about 1/2 inch. next time I will use these.http://www.brphotrods.com/NEW First gen LS1 kit.html
It was just to late and running low on the budget.

I guess I didn't notice it moved anywhere but down when I swapped mine out. Not having the steering box in the way sure makes life easier. The are definitely thicker and more suited for our applications:thumbsup:

so you think this is the kit to go with? I havent bought anything yet..

call them and get the measurements, but I think they are going to be much easier to work with.

Mike, the BRP setup would work. It places the motor more forward and higher in the chassis than most the other more conventional setups you see here.

If I did it all over again I would go with BRP.

The only thing about the brp is the height.. I'm running a victor jr fule injected intake, so I'm a little concerned with hood clearance.. Should be ok but not sure yet.

I also already have t56 crossmember from ATS for the 6 speed in the car.. I'll call brp and talke to them

I had the same concerns. I plan to go with a blower in the future. So I ordered Autocraft pan/mounts and ATS trans mount.
