The big block under the hood makes you forget that you in a two-and-a-half tonne boat. This Buick is a sleeper, looks slow, but isn't.
THE most comfortable car I've ever had a ride in. With almost every option, this car is as luxurious as it is fast.
The 403 is a small block oldmobile engine!
Nice review and good luck with your Buick, however, 1; the 403 V8 in your Buick is a small block not a big block, and 2; it's a Oldsmobile engine not a Buick engine. Also, next time you do a review, you might want to add more details into your review. Just a suggestion.
The previous two comments are 100% correct. The 403 V8 is an Oldsmobile small block engine. It was available in 1977-79 full size Buicks, Oldsmobiles and Pontiacs. GM downsized their traditional full size cars for the 1977 model year, and part of the downsizing was the elimination of big block engines in the interest of better fuel economy. This applied to the full size Chevrolets, Pontiacs, Oldsmobiles and Buicks. The only exception were Cadillacs-they too were downsized (specifically the DeVille/Fleetwood models), but had Cadillac's own 425 V8, which was a big block engine.
*ahem, http://theserviceadvisor.com/part/reman/buickbesttsagmc_403lb.html looks like a buick 403, most likely just an olds engine, but it does exist.
To the individual who posted about the re-manufactured engine website: That same 403 V8 is listed for Oldsmobile and Pontiac as well as Buick. That doesn't mean there were Buick 403's and Pontiac 403's. There weren't. There is *one* 403 V8 and it was designed and built by Oldsmobile for use in Oldsmobiles, Buicks and Pontiacs. GM started sharing a lot of engines between different divisions in the late '70's, especially between Buick, Oldsmobile and Pontiac.
I have driven this this year & model car at least 450,000 miles. The car weighs 3770 pounds. This car is the first totally CAD auto built in the US. All were built in Linden, NJ. If any reader has problems with theirs call me at 610-564-8113. I promise I'll return call. Can diagnose over phone. Just bought 4th for $1000. 34K original miles. Have two definite MUSTS for all: 1) Next oil change use a chemical flush. Switch to total synthetic; 2) 90% of major problems are due to poorly designed catalytic converters. Exhaust flow restricted intentionally to increase torque. New LOW-RESTRICTION converter ASAP. Gas mileage goes from 8-10mpg to 14-17mphg. Over-heating? Change converter NOW! You may have 2,000 miles before you blow head gaskets. It has MAJOR collector potential. They all have the same problems. Don't ever want to drive anything else and am able to buy any type of car I want. I choose these. Bought 1st 8/11/77. 325,000 miles. It's as if they want to run forever.
