I've been using my hands as well, it is effective for most of the bends but I've been thinking about my brakes, and I've just about convinced myself to run 3/16ths lines for the rear instead of the original drum size lines (1/4), in hopes that I will build pressure sooner and haver a sooner harder brake pedal. I also would like to have the adjusting capabilities from the wilwood PN260-11179 proportioning valve, so i would like to nice 90 degree bends and make it really nice and clean. I figure the only things that can make the braking any better would be a big brake kit and new calipers, so before I go or consider that route I want to get all I can out of the 11" rotors and stock calipers and see how I like it.
....also the 327 is coming out, so I can have it sent to a machine shop and make sure everything is true and a good fresh start, then I'm going to install the 69 double hump 327 heads on in addition to a new 470 lift, duration 272 comp cam, double roller timing chain, stainless steel valves, and possibly some roller rockers and roller lifters. Also want to run the "tru-ram" manifolds from speedway motors, which I will choose the cast stainless steel manifolds. BIG QUESTION!: will those straight dump manifolds work/clear the stock c10 crossmember and engine stands? If they don't clear the engine stands then I wouldn't be so against swapping those out for some new ones from cpp, since those look like they'd give more clearance.... In the mean time... There's going to be a 383 that will make itself quite comfortable in those frame rails....
