Ok so update, I cut out the tranny tunnel and opened up the firewall to about 21 inches where the tranny drops through. At first after cutting out the tunnel and setting it on the tranny i thought i did unnecessary work there, but after getting the motor in im glad i did it.
For the guys who want to drop in an LS with a 4l80e transmission you probably wont have to cut away as much as i did ,but the verticle section where the gas peddal sits will probably have to go. I think the fit is just too tight. The rest though you can probably get away with an aggressive message of the tunnel.
Motor looks like it will fit without too much issue and I might be able to run headers or a manifold without cutting out my fender wells.
Ive got everything pretty much where i want it side to side. Just have to get the crank angle just right. The plan is to make an adjustable angle mount.
I cut off the motor side of the truck mount and the body side of the stang mount. I will make a cradle bracket, if that makes sense, on each and weld one side to my 2 inch pipe. The pipe will act as my pivot point and onve ive got the ideal angle i want (im going for 3° tilted back) ill weld them in place and start working on my cross member. Because that mount is likely going to look like crap and will definately be bulkey I will use that as a negative to make a jig that i can use to make a nice tucked in tight mount hopefully with less unneeded welds.
Also got the front end frame mostly finished i stopped cause i spent 2 days straight on in and a little tired from it.
Now its time for a photo dump.
