Awesome project car!!! :prayer: If you were to decide to go down the rabbit hole of installing a 5.7 Hemi, they fit in an E-body with minimum hassle, and you can have power steering. The Gear Vendors OD will work fine, with just a little beating on the trans tunnel with a BFH. I put one in a 71 Challenger that was a column shift automatic with bucket seats, and you couldn't tell where the tunnel was modified under the carpet. That being said......if I had it to do over again, I'd have used a 518 OD transmission instead. A 518 CAN be installed without cutting the torsion bar crossmember. I have a 74 Cuda 360 that I plan on putting a 518 in. Good luck with your project, and have fun. O:)
