I'm building my first 2004R that will be mostly on the street with some drag racing. The Buick 350 will put out 350 to 400+ HP but the Regal will get a 455 after that. I've been reading on different sites of what needs to be done so I hope there is a trans man here to help me out. I read on...

I am rebuilding a Buick 3.8L for my 91 Buick LeSabre. I went .030 over and I am working the heads. I had new guides installed, new valves, which a had back cut 20 degrees and I'm working the head ports just to see if it helps. The Question I have is the intake part of the head where the air...

I first got this Regal because it was cheap and rust free. You know the story, always garaged, grandma's car' few scrapes and dents. I won't lie. When he said 1200 bucks I said I have to see it. After work I checked it out. I got there and the windows were down and he said he started at 4500 and...

I'm going to put the 403 in the Regal for now so who makes the best cams for drag racing and street driving and idle needs to sound bad *ss but how high as in lift and how much duration before gas mileage suffers badly? It is close to winter time so might not drive it much. Does anyone make a...

I'm getting ready to pull the pan on the 307 Olds motor in the Regal and wanting to know what is the rubber rear main seal that you can use? Is JV748 for the Olds or the Chevy?

I wanted to start this thread to see what kind of performance you guys are getting from carb spacers. On my last intake it was set up for a small Holley SP1 for Big Block Buick. I had the 3" Dominator 4500 to 4150 adaptor spacer and found after that I added a 1" phenolic spacer and it went...

I'm building the 462 Buick again and checking endplay. The book says .003-.009. I have .005. I heard this is too tight for Drag Racing. What do you guys think?

I got my 86 Regal with an Olds 307 and thought maybe I would run stock NHRA class but most things I've read is it's hard to get 15's in the 1/4 out of it. I have contacted cam companies about a stocker cam with .474 lift and lots of duration and only one said they need more information. Has...

I just bought some Flowtech headers to put on my 86 Buick Regal until I put a 350 or 455 Buick engine in it. I noticed after checking the alignment of the gaskets that it will leak badly. I have the Zone getting me both exaust gaskets for the round and square to see how they fit. It looks like I...

Hey GBody lovers. I have had another 83 Buick Regal but had to let it go. I have just purchased an 86 Buick Regal and have been working on it since. It will be a drag car in the future but for now a street car. I live in Indy and need some help. Thanks Ron Butz.
