Thanks for the compliment.

I have a few questions for you. Did you weld the chevelle frame brackets to the crossmember? I did not see any bolt heads in your pictures. Also, how did you make sure that the engine was square in the frame? Did you simply use the frame rails as a reference? I am trying to make my plan right now, so any advice that you have would be awesome. Also, you mentioned notching the crossmember for the oil pan, but I do not see that you cut any material away. Would you comment?

Thanks!

i have started notching the backside of the front cross member. its not very pretty.. alot of swaps have shown this isnt needed. I want to use the Fbody air compressor eventually. so I need to move my engine a little farther forward to accomplish that. its easier to hide on the back side.
Theres no bolts because the frame stands are sitting on the front crossmember. Im waiting on my welder to finish up my transmission crossmember. I plan on marking the holes, pulling it back out, drilling them and then i can bolt it into place. Once i have the crossmember in place and the driveline centered and with correct angles.
Actually i think one bolt hole actually lines up. but im going to use a angle finder and and level to double check.
The Edelbrock mounts are designed to bolt and at position the LS within 3/8" of where a small block would sit using the same motor mounts and stands. but they dont tell you what accessories (too many options) or oil pan to use. Well they do recommend a aftermarket steel pan. With Fbody pan and accessorys the holes dont line up for the chevelle mounts. The pan requires the engine to go farther back to drop in. and the alternator vs steering box limits the room to slide forward. it makes a big difference on the driveline angle how close the alternator pulley is to the steering box. But the edelbrock mounts are really thick which should elminate the problems ive seen where others have fabricated their own mounts and having to raise the engine to clear the steering linkage.
