Conversions & Hybrids - first gen camaro question

i have been searching/lurking this forum/site and cant get a good answer. i am building a 67 camaro with an LS3 w/4l60e. what crossmember and engine mount is works best.modified t400 crossmember? i have found answers for the t56 swap but not the auto.my first post here but i thought this was the best place.

bump. my ls3 is ordered.

any info would be greatly appreciated.

There are several options, BRP Hotrods, ATS, STS, etc. Below is information from the forum that would be helpful. The swap has been done several times....though not with the ls3....however it should be no different.

i had my crossmember made at a muffler shop, you should start there they have the tools & can make it to custom to fit your exhaust exhaust

TH400 crossmember is offset 2" to the passenger side. TH400s were used behind BBs and their exhaust manifold wouldnt clear steering box so they offset the entire driveline 2" to the passenger side. You might had to cut and reweld your stock mount on center and the maybe redrill holes in your frame rail depending on engine setback.
