1978 Caprice Ls Swap

[rwd_pete]

The proportioning valve should fix the front/rear split. On Impala SS's there was what was referred to as a "stealth bolt" mod where guys would add a piece of bolt inside the proportioning valve to direct more pressure to the rear. I think the 4 wheel disc master cylinder adds more pressure to the calipers. If you don't have to push too hard on the pedal to stop, then I guess you are OK.
So Ms. Vanessa is your car's name? I call my 56 Ford Fairlane Victoria Ms. Vicky. "Victoria's Secret" is a small block chev. driveline. LOL

I finally bit the bulketcsnd ordered more parts. Got some headers from speed engineering. Spark plugs and wires along with a fuel pump. I also got a stall converter for my trans. I also ordered front accessory brackets from Lssimple. Once those come in the mail I’ll buy the alternator and water pump. Then all is left to do is run the fuel system, out oil in it and I believe harness and computer.

Update! Drove 2 hours to summit and purchased Holley terminator x wire harness and ict coil brackets to clear for the fuel rails. System is pretty straight forward. Just needs cleaned up a bit. I was able to get it started.

Could you describe your motor mounts and how you decided on the placement of alternator? Will the truck alternator/PS bracket interfere with steering components? I don't see a power steering pump. Did you use SBC motor mounts in stock location and set-back plates on the LS to put the bell housing in the right place? Any reason you are going with the servo throttle body instead of a 98-02 drive by cable? I'm considering buying an early 80s LeSabre 2-door with a 307 SBO. Trying to form a plan how to LS swap it or maybe keep it SBO and buy a 350SBO long block. I don't see a Holley kit for B-body LS swap with 4L80... I like the holley hooker mounts I used to put the 2004 5.3L/4L60 in my '84 Monte Carlo - would use them again if they worked in B-body. Also bought a LS1 DBC throttle body from a Trans Am and kept my accelerator pedal stock (had to buy new harness/computer). What is your plan with the exhaust? Nice to meet you - I'm mike. Love your Vanessa!

What header kit did you order for this swap I know it’s speed engineering but which one was it long tube 7/8?
