    LS1/ T56 280Z questions

    in Gen III & IV Chevy V8Z Tech Board

    Posted

    I am finally getting back to working on my LS swap after 10 years of it sitting.

     

    I initially installed my LS using John's Car's mounting kit several years ago. I have since put Austin Hoke's mount kit in.

     

    My original Sanderson shorty headers would need mods to work and I'm looking at Hawk's and CX racing long tubes. Leaning towards the CX ones as they appear to fit tighter under the car and in the engine compartment. I realize they are smaller primaries, but I'm not worried about finding the last few horsepower.

     

    I'm using a C&R 26 x 19 double pass rad with bar and plate oil cooler, does anyone know if I'll be able to route oil cooler lines between the block and headers? This would be very tight with the Sanderson's.

     

    I'm pondering the Silvermine electric power steering kit. will it clear either Hawk's or CX? Read in a post that on a 280, the EPS hangs a bit below the dash, this may be an issue for me as I have a prosthetic left leg and with no ankle joint I have to deliberately put my foot higher on the clutch pedal.

     

    Also looking for opinions on cooling fans, any idea how many CFM a LS would need? Running A/C, so there will be a condenser out front also.

    The core is 22 inches wide, and looking at Spal catalogue it looks like I can just squeeze one 10 inch and one 11 inch fan on a custom shroud.

    Combo would be well sealed to the rad support and ducting between the grill and support will be installed.

     

    I'd like to run dual fans, so the trinary switch on the A/C will trigger the second fan. 

     

    Thanks in advance for any ideas, opinions, and pictures, Martin.

    I'd be pretty leery of this swap. These motors are notorious for having the head bolts strip out of the block. My STS is sitting in my shop right now with this problem. It's a nice motor, but wide, parts aren't cheap, not many performance parts, and you can't get undersize bearings for them.

    I really wish I could forget about fixing mine and just put the time and money into my 280/LS1, but I need my carpool car. Good luck with whatever you choose to do, there's alot of Northstar info at cadillacforums.com

    Fan CFM needed to cool LS1

    in Gen I & II Chevy V8 Tech Board

    Hi,

    What fan CFM is needed to cool a LS1 in my 76 280? I'll be using a 19x26 aluminum 3" thick 2 core Northern rad. Unfortunately, the fin area isn't wide enough (side tank style) to use the F-body duals. I've read about the Taurus two speed but don't like the high amperage draw. I want the fan to trigger from the PCM and from the trinary switch on the Vintage Air. Any suggestions?

    Thanks, Martin

    LS1 water pump

    Hi All,

    Does anyone know how the heater hose nipples are installed in a LS1

    water pump? I want to run my heater hoses 90 degrees up and hide them

    under the fuel rail cover. Wondering if I can pull the nipples out and tap the pump for 90 degree pipe fittings, or will I have to TIG weld a 90 to the

    existing nipples?

    Thanks, Martin

    Revisiting: Spot calipers as parking brake

    in Brakes, Wheels, Suspension and Chassis

    Posted

    I talked to Dave at Arizona Z about using the spot calipers. He felt they had a tendency to drag, and if they jammed they could snap off their mounting ears and spin around and smash the actual brake caliper. He also said he may look into some form of a parking brake for his set-up. that was a few months ago, I know he is a very busy guy building some beautiful stuff but hopefully something can be made to work.
