Re: 1971 5.3/4L60E first time swap

Big Update guys! motor is in! it was the fastest motor install ive ever seen. Our engine hoist operator got a little carried away with turning the handle to lower it down slowly.... balancer left a small dent in core support but it went in smooth other than that lol.

The Speed Engineering Headers fit great!

The transmission wasn't quite centered on our crossmember, so i loosened all engine mount bolts and was able to pull it to the middle by hand.

Only loose ends are
1. Drive shaft taken to be fitted/shortened.
2. Figure out how to get proper radiator hoses to fit 5.3 to our Aluminum radiator we had gotten when it was still a 350. (any Ideas guys?!?!)
3. make custom transmission lines uses 6-AN fittings
4. Have a High pressure power steering line made
5. Get 3/8 line I Bent Brazed into our sending Unit
