Re: Swap Mounts

Everyone I have seen use them have liked them. I personally used som $30 ebay 1" setback plates and standard sbc mounts. Cheaper and does the same exact thing.

Re: Swap Mounts

the 1" plates and hawk/spohn swap mounts are one of the few dead-on, no issue parts of the LSx swap. its everything else that needs work

Re: Swap Mounts

I used the set back plates as well and welded solid mounts the k-member and used stock SBC mounts. Everything lined up and dropped in. never even had the passenger coil even come close to the heater box at all. I didnt even have to notch the k member at all and ended up hitting the inside with a ball peen hammer after I flattened the welds and everything cleared good

Had a bit of an issue getting the last long bolt through the mount. Didn't matter which side I put in first, it was fine. The 2nd one required some "persuading".

2 different sets of mounts, same exact issue. had to loosen up the kmember to clamshell bolts all the way, still had issue, but much more room to play with adjustments.

motor from storage shed to driveway: 5 min
motor from driveway to engine bay: 5 min
installing 2 motor mount bolts: 1.5 hours + a very colorful monologue with the car

Re: Swap Mounts

I am trying to use some Dougs headers set back plates and the stock SBC mounts. Is this what you guys are talking about or are you talking the spoon mounts?
