Can anybody on the V8 Buick site point me to a link where I can get the general specs on the 73 Century/Regal GS 455. I believe there are two horsepower ratings, 240 and 270. Thanks for the help.
the gs455 was 240 hp, while the stg1 was 270 hp. don't know of any real site for 73 gs's alone. just from my experience. john
Thanks John. I located some information on the NHRA website. They have specs for the '72 and '74, but not the '73. I'm just guessing that the '72 specs are pretty similar as they list both the 240 and 270 horsepower versions. I'm guessing that it won't take much magic to get a '73 well over the 400 horsepower threshold once all that emissions crap is eliminated. Mark
