You are, Ken.
The 350 10.2 is a Chevy motor. Number 6 is for the 1.09 venturi, 750 carb.

Again, not available in the Skylark until 1979.

The specs you are looking at in this thread are pulled from the NHRA tech site, where ALL the engines used by Buick , in ALL body styles, are listed together.
Go to Dwight's site and use that .He's already sorted them all out for you.

The 350, 9 to 1 listing is a Buick engine. It uses the 1.21 v, 800 carb.

Doesn't anybody know how to use the Classification Guide??????

Look at the combo in the classification guide, look at the blueprint specs...That will tell what class you would run by the weight breaks and what the engine are for a 1977 Skylark

These are the only engines available in a 1977 Skylark according to the NHRA........


231..V6..Buick....301..Pont..........305..Chev


Factory HP
105hp............135hp..................145hp

NHRA HP Stock
130................155.......................180

NHRA HP SS
140................180.......................190

Locate the car model-body in the left column, find the engine along the top. Where row and column intersect is the power to weight factor. Click on that number when it turns yellow and it will return the classes, weights, indexes that the car fits. A button at the bottom of the page will take you to the engine blueprint specs including all the legal pistons, rods, oil pans, cranks, blocks, etc. Some cylinder head listings may have some flow data available.


Merry Christmas!

Now the next problem, how am I going to make a 2bbl 305 run low 13s in a 3200# car

To me...that is the fun of it

you have to go over every part on the car looking for an improvement

So engine wise what are some things you can get away with? By no means are these motors stock. Lots of rpms? Perfectly balanced rotating assemblies? What are some tricks that you are willing to share?

Patience and Money. You will likely have to spend a lot of both.

Seriously, if you want to do the engine yourself, you need to find some local racers and or a machine shop that has experience with stocker engines. Making power that passes tech takes a lot of trial and error. There is not really one magic thing. Everything has to be as good as it can be. Of course, start by picking a viable combo.

If you pick a V6 combo vs a 305 for example, they want different things.

I would say to research the rule book and the classification guides. See what classes the combos fit in. Order stats from Nitro Joe and see how others in those classes run.

You probably don't know enough about it to even ask the right questions yet. The more base understanding you have the better. ( before you choose).

If there are local association races or you have local class racers near you, get to know them. Have them show you their cars. I think that will help get you started.

One of the big things for you to remember, if you're going to run the 350/2V combo, will be to keep everything in harmony. You will be building a severely restricted combo. You're going to have to choose your cam very carefully. You can't afford to leave a few too many cc's in the heads, or a few thousandths too much deck clearance in it. Go to somebody that knows what it takes to build a set of "Stocker" cylinder heads. Don't put a 7500RPM cam in a 6000-6500RPM motor. Find every Rochester 2V that is the correct size for a 305 that you can and find somebody who knows how to use a flowbench.
THAT should get you started!
