So I found this Engine for $250. It ran when pulled lol. We all know what that means right. I would like to keep this build between $2-3000. And do most of it myself. I just want something reliable that sounds good. I also have a rebuilt 200R-4 to put behind that I’m going to swap at the same...

I replaced all the guts in my distributor. Module, rotor, button and cap. I got a distributor out of a local salvage yard and used a couple of parts off of it because the wiring harness was in better shape. The problem I’m having is that it runs good at idle but when I put it in gear it starts...

I have a 1984 Buick Regal Limited with a 3.8. The issue I’m having is that I have to pump it about 10 times for it to start. It will start and idle just fine and then it will just start to hiccup and run choppy. It will run like the 125 hp beast that it is at high rpm but at idle and low rpm it...

I can pick up an 85 t-type engine with 55,000 miles on it. It was in a wreak 20 years ago and hasn’t ran since. I would love to put it and a 200r4 in my 84 regal. What do you guys think that motor is worth and how much would it take to get 300hp out of it? Here is my Buick. I have a aluminum...

my blower motor would not work on high so I put a new switch in the dash and that fixed it. A month later it quits working so I replaced the relay and come to find out it was the fusable link. All the wiring seems like it is in good shape. Has anyone had this problem or have any ideas on what...

Does anybody have some good pics of their engine compartment? I have a 84 Regal with the 3.8 and AC. My smog pump is missing and the wiring is a disaster. I know there are schematics out there but my brain doesn’t work that way. Any help would be appreciated.

I’ve been trying to figure out the lights on my instrument panel. The fuse is good. All the bulbs are good. I’m sure the light switch is good because it turns on and dims the courtesy lights. I finally found the culprit. The fuse is not getting any power and it’s the only one. I also found two...

My 84 Regal has a stock 3.6 and has no problem starting but it seems to idle at high RPMs. The engine wiring seems like a mess and the thermac plug is missing so if anybody has a pic of it that would be helpful. Other than that the car runs and drives pretty good. Thanks for the help.

Does anybody have any pics of how the grill is attached to the body? I know it uses springs but I can’t figure it out. Thanks

I picked up this Regal from a salvage yard for $100 and have been working on it for a couple of years. It wasn’t too bad except for the paint as you can see. It’s definitely been a challenge since I’ve never worked on cars before and I don’t know what I’m doing lol so I pretty much wil be asking...
