So I've been doing all my reading started gathering parts and got started. Engine is a aluminum 5.7 from an 04 vette. 44000 miles dissasembeled gapped rings for the blower got a nice cam and springs new gaskets put it all together. Got new fuel pump trans dapt 1 inch set back plates and pacesetter headers. Sold the engine and trans out of the car ( kept the f1r) and here we go

Engine out ready for new one

This is where the mounts were

Set the new engine in

Doesn't fit hits the cross member with the new gm muscle car pan. But just barley so I try and move the mounts to a slightly further back position fight that for an hour. Doesn't work so I put the mounts back where they were and decide to "clearance" the cross member

Ignore my high value of safety equipment (bare feet) with a plaza cutter
Set the engine in again for another hour fight. Now the engine goes down but the mount holes WILL NOT line up the adapters do not fit properly or I'm missing something it is midnight and I'm 4 or five whiskeys into the evening any one else seen this


Any ideas!!!

Same issue here. Ended up using the Transdapt standard adapter and installing them 1 hole back (sets engine roughly 1" back). Cleared the crossmember.

Getting the bolt holes to line up was impossible for me. Others have had success, but the 1/8" thick adapters seemed to just mess up the geometry enough since the frame mounts are angled (I am using Moroso solid mounts). I even tried loosening the frame mount bolts and had issues.

Solution- I dropped the motor in where I wanted it to be side to side. Made sure the car and engine were level and tacked the solid mounts in with my MIG. I was able to utilize a few of the frame holes, had to open up a couple a bit and it works great. Since you have a plasma I assume you have a welder 8)

I am sure others have a better solution, but this is what worked for me.

Ya I have a welder, and I think Im going to bolt the mounts to the block set the mount pad on the frame set up the engine angles and such and get them where I want it all to be. I may be able to get it moved back a little more that way also. Tack both lower mount plates to the frame then remove the 2 long bolts pull the engine back out and drill some new holes wherever they lay. Then since they are the 3 piece mounts I can run a bead all the way around the lower plate to the frame. sounds good!!??!! oh ya then box in the crossmember also. Ill give you a shout before I pull the welder out so you can join me with a few water buckets.......

The worst part is the trans dapt plates that are "designed" for this I paid for then when I got them they were prerusted and paint flakeing off in the box so I had to spend another 30 on them to have them cleaned and powder coated. What a joke product....

That is exactly what I did in terms of having it bolted together, dropped down, leveled and then tacked the frame mounts. Pulled the motor then drilled the few holes that needed to be opened up, bolted the frame mounts down, dropped the motor back in and BAM, perfect.

trans dapt = made in china crap. call their customer service or tech line.....
I've never had a customer of mine call with that problem as long as they used shells and frame mounts that worked with their distributor chev engine. Even the moroso solid mounts are imported quality and usually require a little "massaging" to fit stock applications.
Also, mine are aluminum and don't rust.

What kind of mounts do you have?

I'm not being secretive, [-X I'm not an advertiser, so I can't openly discuss the plates that I "use" because it steps on paying advertisers toes. I've been warned by the administrator already.
By the way, you have a p.m.

Question guys when you're doing the LSx engine swap, do you use the same vaper canister that came stock in your gbody or do you have to buy vap canister that the late GM vehicles with LS engines in them use?
