TA Performance has the high and low compression pistons for the 300/340.
Or, take it to a "Test and Tune" day at your local dragway armed with your timing light and a jet kit for your carb. It would be more fun and less expensive then your tuner.
Welcome aboard Butch. 67 is a great Buick year!
The 64 Riv had a ST 400, but it was not a switch pitch like the 65-66 Nailhead ST 400. They are dimensionally the same size and bolt in the same location using the same mounts. The fixed pitch...
Alex, The 1963 4 barrel carburetor 401 (JT) was advertised at 325 hp. The 1963 2 barrel carburetor 401 (JR) was advertised as 280 hp. It will have more grunt than you think.
The engine code...
Scroll down below where you post when responding and you should be able to click "Manage Attachments" in the Attachment section. Amy picture in your computer should be fair game from there.
A 69 Cat would have a 430. That is a good strong engine already. Pictures are always appreciated!
Welcome - Steve
This should not be that bad. The mounting is the same. The bell housing is correct. You will need a flywheel for the 425. You will need the correct flywheel bushing for your transmission and the...
Be sure to check your brake lines and hoses. I don't think the rear reservoir was empty by coincidence.
That is a head casting number common to both the 300 and 340. The difference in compression in these engines was in the CC of the piston crown and depth down the hole.

That should be a switch pitch if original from 67. But, that was a long time ago and transmissions wear out over time (even the durable ST400). You will want to check the date and Id tag on the left...
Yes, the 400 in LeSabre 400 was the ST400 transmission. It was an upgrade option from the ST300 transmission in 67.
some serious kackle there!
You could have had a lifter bleed down overnight. I would take it for a short ride and see if it is still ticking when you return. Some of the lifters out there today are not up to par, but let's...
Some drums have the min tolerance stamped on them.
I have heard it explained that the date code after the production code on a Nailhead is the numerical shift number of the production year. My 65 GS was produced in the first week of August (08A),...
Depending on whom you ask, 1600-1800 RPM.
The Q-jet and manifold were only available on the 66 425 and some 66 Gran Sport Skylarks with the 400 (401). No other Nailheads were ever equipped with them from the factory. So, yours was a...
Keep it above 2000 rpms during the first 20 minute break in and vary the rpm some. Don't rev it and make incremental changes in rpm. Let it cool all the way down after the break in period before...
The Riv had the only Buick "X" frame in 1966. That is much different then the other big Buick frames.
Check the procedure in the 67 Chassis Service Manual we have in reference section on this site. It will be the same for a 67-69 430.
