Anyone have any experience with a riviera? Or old Buick 430's in general? One in fairly decent shape... supposedly with original running gear and in running/driving condition just popped up for sale right down the street from me. I'm going to go look at it this afternoon. Any advice or experience... things to look for other than the usual rust and poor body repair?

Well, I bought it.... so it's all your fault for not saying bad stuff about a Riviera. Getting the title transferred over and some decent tires on it today. Hopefully I can get the fuel system working and get it fired up tonight or this weekend. Its got a 1970 455 in it with true duals and glass packs.... so it should make quite the ruckus

UHHhhhhhh....
Sir.

Where are the photos?
And other pertinent information?
Well, no-one responded to the initial post... so I was holding out on providing any automotive porn. By the time I had bought it and had it towed home after work yesterday, it was already too dark for any pics. I'll get some today when I get home from work. I had a hard time finding some decent used tires for it, so I'll need to do some more scrounging until I spring for some nicer ones. Just gives me more reason to burn the old ones off without feeling the burn in my pocketbook.

Oops, got sidetracked with stuff around the house and my wife’s 2011 burb lost all forward gears on Friday… so yay transmission repairs on the 6L80 again. Pretty sure it cracked the 1-2-3-4 piston, which was original and has 205k miles of abuse on it.

I did manage to get fuel to the carb and momentary firing, but I need to rebuild the Holley carb on it before I think it will run. It’s just flooding bad as it is and leaking out of everywhere. Also found out that a freeze plug on each side of the block is knocked out right in an easily accessible location… not sure what that’s about, hopefully it was just for long term storage. I bout two new plugs at the auto parts store for $2 and will point those in with some sealant after I get the burb driving again.

That looks like the bones of a sweet cruiser for sure!

You may find some good deals at the Portland Swap Meet this weekend.
Maybe even some wheels and tires.....

Hahaha, it came with wheels and tires... not very good ones, but they are there. I have them of so I can inspect everything and get the fuel system sorted out. The fuel tank was crushed up at the back and had at least one puncture hole in it. I decided to work on getting it running and making sure it was healthy first.

Tried to crank it with the fuel hose dropped straight into the fuel tank you can see in the pics above. No dice. Cranks well and tried to fire, but never lit off. Little bit of troubleshooting and fuel was flooding out of the holley 4160 and no spark. Pulled the carb and rebuilt it.. flooding fixed but still no spark. Seems like there is a break somewhere on the ignition power, so I just made a cable to go from the battery straight to the coil resistor input. Also the R45TS(wrong plugs) were totally fouled, so I went and got some correct R44TS plugs. Stuck them in and hooked up the drivers side wires so that I could check timing before firing it up. Bumped the starter and it fired right up!!!! Ran fairly smooth but definitely seemed like it was weak, quiet and not as snappy as I would have expected:(

Then my neighbor came over as I shut it down and I started chatting with him on the passenger side of the car. Turned around and realized the passenger side plug wires were still laying across the fender :eek::banghead: .... how the F was it running like that on only one bank :happy175:

So I went and plugged in the passenger side bank of wires and cranked her up again.... holy cr@p!! Its an absolute animal. I definitely need to get a full exhaust system that is bigger than the POS 2" with glass packs exhaust on it now. I've seen some nice dual 3" systems and maybe some decent flowmaster 50 series mufflers to keep it a reasonable volume inside while cruising. Headers, exhaust and mufflers are gonna run around $1k. Full interior redo is about $2k. Just ordered a fan shroud and all new door/trunk rubber for $300. It should make a nice fun family weekend cruiser and maybe a bracket race car in the future.

I had run a compression test when I pulled the plugs and its about 180psi in each cylinder, so she's a healthy, original 10:1 compression 1970 455. Still has the switch pitch TH400 in it.. seems to be the original trans to the car. I pulled the fuel tank and it is super clean inside. It was banged and dented up and had some rust pinholes on top and a big cut through the back. I cut a hole in the top where the pinholes were and banged out the dents and flattened the area with the hole. I'll weld up the cut area and put in fresh metal on top where it was rusted through before welding the cut out piece back on. I was going to just order a new one, but they are $300 and almost impossible to find.

I forgot to takes pics again... so I'll post some tonight when I get back out there to work on it and finish patching up the fuel tank. The only thing left to evaluate and make sure it's right before driving is the brakes. Once I get all of that straightened out, then I can hot wire the ignition and drive it up on blocks in the shop so I can start figuring out where the wiring is messed up. Basically none of the ignition wiring is functional including the windows and driver seat power. Interior lights and starter work as they should, but thats about it.

Yep, it's a boat just like I thought. Looks to be a very sturdy boat to begin with too.

That about sums it up. Its funny how much the body lines look like the camaro though. If you chopped about a foot off the front and a foot off the back, it would probably only be about a foot longer than a 67 Camaro:happy175:
