    Just rebuilt motor in my 78 Z28, it is now a 383 stroker made 407 horse and 475 ft lbs of torque on the dyno.
    I was told i may need SFC with that kind of torque? if so any recommendations of SFC and what fits the best on a 78 Camaro, 4 speed car with stock drive train.
    Any help appreciated
    Thanks

    Don't buy the competition engineering ones if you have a newer gen2 camaro they won't fit inside your subframe rails without spreading or removing some metal.

    I went with Custom Works. They fit perfectly and work well

    You'll also need to use solid frame mounts too

    I bought Custom works SFC from Keith back in 2019 just getting around to putting them on now and i need some opinions on how to support the car whether to use jack stands with tires off or use my tire cribs i made with tires on.
    I heard its easier to weld the rears with tires off but where would you put jack stands to support and what would you do for the front? Would like opinions from members who used Custom Works sub frame connectors.
    Thanks for the help

    I use cribs and if you want to remove the rear tires put the axle on jack stands which will keep the loads in the same places if you keep cribs under the front wheels..

    I would ask Keith but I'm pretty sure he told me to weld them with the weight on the car tires. I think jack stands on axles would be fine but he's a phone call away so reach out. He's probably installed them once or twice. I have the ones he sells and welded mine on the cribs with engine, trans and most of interior except door panels.
