Thanks for the compliments guys. I'm in Northlake, just west of Chicago, where 290 and 294 meet. What about you 79?
Finman, I don't know if the Hookers are all that much cheaper than the Miller's, but I don't like mini-starters, and you need to run one with the Miller's, so the choice was made for me. As it turns out, the full-sized starter fits without any problem with the Hookers, you could change it without touching the headers. I hung the headers in their approximate position with coat hangers and dropped the motor on top of them. There was a slight interference on the passenger side putting the motor in, but once past this, it was easy. The frame mounts are your typical Oldsmobile ones. I've heard that the motor mounts themselves are different for 307s and 455s, I'm not sure about this. I went into O'Reilly's and asked for a set of motor mounts for a 1970 Olds 98, and that's what I installed. Lined right up, and as you can see, even with the Edelbrock Performer and the medium height air filter, it clears the stock hood.
I don't have any good pictures of the headers installed in the car, I'll try and get some for you. Here's what the headers look like, you can see the one primary that sort of loops out. I currently have very small tires on the car, but I don't have any issue with the turning radius. I park in a pretty tight garage downtown, and I think the furthest I've gone is 1 3/4 turns on the steering wheel either way, and they didn't hit. To keep from having a problem, I'll just put 215-65s on the front.
It took me almost no time to find the axle. The first and only cruise night I've taken the car to so far, a g-body buddy of mine mentioned he knew someone who had an axle, that's who I'm buying it from. You just have to put the feelers out, you'll find one. Toby might have an extra one.
I think eventually I'd like 3.08s, just for a slightly lower RPM on the highway, but 3.42 is close enough for now, and I have experience with a car in this range and it's not that bad, so it may work out. And if I drive 64 MPH with the 3.42s I'll be at the same RPM as 70 MPH with the 3.08s. Not a big deal to me.
Burgundy, big blocks don't really cost more than small blocks, and on the upside, you can spend a lot less on a big block, and you'll have a milder, more docile engine that makes as much or more power than a wilder small block. Plus, you get to say you have a big block.
At this point, I am dying to get back to working on and driving the car. I'm glad I got it drivable before the winter, but then just when I was starting to have fun, the snow came. Next up is that axle, interior restoration, and some baseline runs at the track, in no particular order...
