Some more info for your LS swap D,
No more Gasoline powered Vehicles by 2050? I find I kinda don't think so.
Here's an LSIII going into an early Nova Wagon. Worth watching. Nice shorty headers that look promising. Then, at 6:20, She goes into detail concerning the motor plate/engine motor mount components. Mentions difficulties with the AC drive, and names some suppliers in the video. Funny flexplate lessons. Flip Flops made me cringe, but one loaded ratchet to a toe will cure that.
Hope this helps. Good American Family Fun Video. Cute Dog, Good Skills, Nice Car!
Quality Chevrolet never could get the correct lower mount for one side. I ended up chaining down the high side of the motor in the Impala. '73, '74? Always a good idea anyway. Especially a 283 backed up by a PG...
Traded that $250 '65 Impala to my BILaw for a '59.
The drivetrain then went into his Econorail.
Carlsbad Raceway is buried under a Business Park now. But the Heartbeat of America lives on.
