75 280 Chevy LS swap runs and drives

Eight months ago I started swapping a 1999 Chevy 4.8 V8 (LR4, poor man's LS1) into a 75 280 four door sedan. Two weeks ago we went for a first drive. There have been multiple low speed drives since then as I work out the bugs. One major bug was that there wasn't enough steering travel so I shortened the steering arms and moved the Toyota Corolla rack closer to the ball joint centerline. That was about 20 hours of work in and of itself. I have also managed to tune out most of the bump steer. Anyway, it's 100 degrees here in Sacramento today so I'm taking a break from the heat to type this. No new pictures at this time because photobucket isn't working but here is the link to the original build thread:

Very interesting! It's hot here in Nevada City also. I'm interested in the rack & pinion conversion-I have often considered the feasibility. Is it power?

300td 4 x 4,

Have you been to the place in West Sac that custom makes brake hoses to DOT specs in rubber and braided stainless, inverted flare and bubble flare?

I came across them when I was looking for USA made brake hoses for my wife's '61 190SL. The concept of made in China brake hoses is positively scary to me.

It's even 100+ degrees over here in Sonoma County.

How is your turning radius? Is it close to normal? The Ford R&P I have in my '66 250S is horrible and I need a better replacement with more rack travel.

I don't know my turning radius but it was unacceptable when I first installed the rack. The steering arms are 6.5" long stock. I shortened mine to 4" by heating and bending then moved the rack closer to the ball joints. My steering radius is acceptable now but I'm sure it is still not as good as MB's legendary radius.
