Hi all the car is almost ready to be put back together all I need now is bearings and gaskets to finish the Stage 1. I have two sets of gears I can put in the Chevelle I just wanted to know what would be the best to use. I'd like some fuel efficiency :grin: even with a big block but I don't want the thing to be weak off the line. I have a set of 3:42 posi's & a set of 2:96's kicking around what would you guys use. I am leaning towards using the 3:42 the car will mostly be a cruiser but every now and than I'd like to tear up the track and smoke anyone who doesn't respect the Big Block Buick transplant:Brow: or should I step up to a 3:73 gear. Thanks for any advice.
I think the 3.42's are a great street/strip combo. If your crusing speeds have a little more rpm than you like, just put on some 28" tall tires and knock it down a bit.
the 342s are the way to go , i have them in my gs with a 28" tire it cruises great and it still moves very well at the track . mike
I have 3.73 and am getting rid of them. You will be buzzing down the highway at almost 3300 rpm's at 70 mph. Stick with the 3.42's or 3.55's.
Should it be possible to break 11's with 3:42's ,slicks and a 500 hp BBB???The car should way in at 3500lbs.
my car ran a 11.90 at the track the first time out and i weighs 3500 and makes around 500 hundred horse power with 342s.mike
Hi there, Just thought I'd say hi to another Buick guy on the rock.....not many around anywhere never mind here in Nfld. I use the 3:73's in my '70 St 1 and find it ok on the highway @ 3000 or so but most of the driving is ariound the city. Drop me a line at fmcgrath@nf.sympatico.ca if you like.
