ls swap engine mounts ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jht3rd · 05-24-2010, 06:56 AM

Buying things for my upcoming ls swap. What engine mount adapters did you use? I want to use the truck manifolds and have room for the AC Compressor without to much trouble. I like Ece's but if I could get a forty dollar set off ebay that would be great! I know it would be cheaper to make them, but dont have the equipment for that.

Interested in knowing the magic combo also! If I remember correctly, the ECE mounts and POL frame mounts are the setup to use, but I am not 100% sure. I'm sure someone else knows...

1st of all, you wont be able to use the LSx compressor unless you are planning on cutting the frame some. You can use Kwickperformances high mount for a Sanden compressor.

Mounts: If it were me, I would spend the $ on ECE mounts, from what I understand you can use stock Trailblazer SS manifolds with them, otherwise you will need to use POL (http://www.performanceonline.com/sto...cat=455&page=1) mounts, this is what I used, they work really well putting the motor up about 1" so headers will fit, but the stock manifolds wont and fbody mounts wont either. Hope this helps.

I used the POL stand/mounts and then made my own adapter plates to go from the sbc 3 bolts to the genIII 4 bolt patern

The pol mounts move the motor forward and up. I tried to keep my motor in the stock 6 cyl location for balance, but the pol mounts put the motor a d trans up too high, the 4l60e hits the tunnel.

I am using stock frame pads and prothane versions of the 6 cyl mounts, with cheap steel adapter plates from summit.

jht3rd · 05-25-2010, 01:13 PM

I would like to run the 4l60e also. Is the ece kit complete or do you still have to order the adapters like with the pol setup?

I ended up using a high hump tranny cover with mine. I'm not 100% sure if I would have had to. When I set my cab on, the tranny was hitting the low tranny hump area, so I cut it out, then I realized the drive shaft was also hitting the cab, so I ended up moving the tail of the transmission down.

ECE kit is complete...I think (well, minus the LSx mounting bolts). Its what I bought for my swap.
