    1987 Buick GN for Sale

    I am the 3rd owner of this Grand National since my purchase back in 1998. The car spent most of its life in Texas until I moved to Oregon in 2002. I have spent countless hours, (and dollars) working on this car to restore it to a reliable, performance muscle car. The Grand National has been a...

    oil fitler adapter

    I just got the Precision Turbo oil filter relocation kit and it is a very nice assembly for the money. I can't believe I never install this sooner as it keeps the turbo feed with fresh oil directly from the filter assembly. Anyways, I think I lost my original oil filter adapter bolt because I...

    Found the water leak

    I first noticed it when my windows were unusually foggy in the morning, then I found the wet passenger floormat. After reading a bunch of posts, I decided to re-seal the heater core and replace it while I had things apart. After the heater core replacement, I got out the hose again and sprayed...

    pulled intake for lifter tick

    Had to pull the intake for peice of mind, I have gone about 1,200 miles on a comp camps ductile roller and was tired of hearing the slight off idle tick. It is a tick that is most noticable when coasting to idle or slightly off idle, but I can hear it in the car if the radio is not on. I know...

    Install Hooker Ex

    Got a hooker system and removed my 2-ch flowmasters. The pipes and mufflers were top notch for the money, nice bends and fit. The instructions with the kit are terrible and they give you hardware that you don't need IMO. I haven't done much driving yet since I found my poston DR replacement...

    chain slack effect on cam

    Is the spring on the stock tensioner weak? I pitched mine after my last cam change and now I was wondering if the tensioner every did anything more than just keep the loose slack of the chain in control. I would think a camshaft, with all the valve spring loads, would have a tendency to...

    double roller chain

    How loose is the double roller timing chain supposed to be? I know it doesn't use a tensioner like the OEM single chain, but my engine builder told me he was concerned with the amount of slope in the double roller chain that comp cams provided. He actually go another companies double roller...

    roller rocker life span??

    I am in the middle of an engine re-build and I am trying to decide if roller rockers or stock rockers are best for a mainly street driver with occasional strip runs. I have heard from a friend that aluminum roller rockers will not last very long in a street car and that the stock set up is much...

    Wiped #3 intake, what now?

    My 87 developed a light ticking noise at light throttle and idle. I thought the noise might be a stuck lifter or maybe that one of my adjustable pushrods had loosened up. WRONG.... The noise presisted and got worse, so I removed the intake last weekend, I discovered that I had wiped the #3...

    I have two quotations on a full paint job for my 87 GN and I wanted to see if someone with more painting experience feels that they seem out of line? I have been quoted $4200 and $4000 for completely repainting the car. I know from examples that both of these shops will provide a great paint...

    Passed Portland, OR emissions

    Passed the OR DEQ tailpipe test yesterday. I didn't do anything special like change the oil or run gas cleaners before hand. All I did was put my old poston 36lb thumb wheel chip back in the car before testing, set the chip to stock and crank down the FP. OR runs an idle testing and a dyno...

    FYI...good muffler prices

    FYI...I found this website the other day when I was looking for some new mufflers for my mustang. They had a huge deal going on the Borla (stainless steel) turbo mufflers. These mufflers are IMO better than ultra flows. The bolras are basically the same construction as ultraflows internally...

On some shifts, the Knock goes from 0 to like 45° and within a frame of the shift the system voltage drops substainally to...
