Hi Gents, I'm a nubby to Buick,

Hello everyone,
Although my father was a Buick-only owner all his life I've run through all the US brands as well as a few foreign ones. My last "old ride" was a 64 Plymouth Belvedere which I sold after having a stroke ( that's life! ) Having recovered about 80-90% I'm now looking at a less than 50K mile 71 Buick Skylark - two owners. Here are my questions:

- I understand that the 350ci , 2bbl engine was the start of the "smog " motors , had only about 8:1 compression from the factory, and was a nice grocery-getter but not much potential for any performance without some serious work. What would you recommend ?

- the 350 have a few issues from the factory - 1) needs an updated oiling system 2) if you convert to a 4 bbl , the 350 likes fuel so going with a 650cfm+ from the start is not a bad idea. What would you recommend ?

- from the TA Performance site, it appears that the 68-70 10 bolt was relatively strong, and did not have the c-clips like a chevelle. What about the 71 ? is it a c-clip rear, and if so, what would the recommendation be for installing a Posi ? Manufacturer ? This is going to be a cruise night car with "maybe" a trip down the 1/4 mile ... once a year at a nostalgia event ? Considering 3:42's ?

- Will likely go to dual exhausts. My thought was to start with the 1 5/8 headers . Any recommendations on brands ?

I know this is a lot of questions and in advance I want to thank anyone who takes the time to respond.

Best regards,
Ted
 
Im not too familiar with the buick 350 (i believe some of them can have oil pump issues).....As for power there is definite potential....My uncle (when I was 8 or 9 yrs old) had a green on green on green 72 Lark GS 350 ram air that ran pretty darn good for what it was....His had the BOP 10 bolt with 3.55:1 gears......And yes, the buick, olds, pontiac, 10 bolt is a bullet proof rear end but because it's not a chevy 10 bolt (totally different internals, different axle splines, pinion splines, etc) gear selection is going to be limited.....I think the closest you'll get to 3.42:1 is 3.55:1....Auburn sells a nice LSD unit for it, I believe Eaton sells one as well...Check out (drivetrainspecialists.com) and (drivetrain.com).....They should have what you need.....
 
The 71 350 can be made to be a fun engine. Just needs a little tuning up.
Go with a quadrajet. Stock Buick quadrajet for a 71 350 was 750cfm. A stock Buick quadrajet intake would perform fine, and there are some aluminum options out there. They save weight, but don't have much power gain.
I have a 71 Buick 350 Quadrajet that I am currently building. It will be ready to ship in about a week. www.quadrajetpower.com

The other thing you need to do is work on the distributor to bring in your advance quicker and set your total timing, not initial timing. I have a sheet that describes this. Send me your email address and I will send that timing sheet to you.

The 71 rear diff in the Skylark was an 8.5" and they are great. I have been racing with one for years in a 10 second Buick with a 3.42 gear. Axles are bolt in. And parts are readily available for the 8.5" 10 bolt.
