I think you are right. We have a partial list of casting numbers for the small block Buick here: https://www.teambuick.com/reference/casting_numbers_300-340.php. I cant quite make out your intake casting number, but you may be able to confirm it is a 340 using the intake casting number. The...
If it has four bolt valve covers it is either a 300 or 340. If it has a four barrel carb it is most likely a 340 as there were no 4 barrel 300s in 67 - only 2 barrels. If the engine is not original, all bets are off!
Six bolt valve covers would be a Buick 350 from 68 on. They are almost a...
There are some conversion companies that sell all the parts to convert to a T-65 manual. You will need a specialty BOP to T-56 bell housing or a mounting plate adapter that will allow the T-56 to fit a BOP bell housing. They have kits for the larger chevys that will share some of the parts you...
I think you can remove the steering arms with the car suspended, but be careful of any rubber boots if you use a pickle fork. Make sure the back tires are immobilized too. I am still not sure that the front of the pan will not get stuck between front main cap and frame crossmember when you...
Hopefully you are secure on jackstands first and foremost or up on blocks with the wheels chocked. You don't have to remove the mounts, but just the bolts that connect the mounts to the frame pads. Then you need to lift the engine enough to slip the pan out the back. You may have to remove the...
Yes the flywheel cover will have to come off, but you will also need to take the bolts out of the motor mounts and lift the engine some to get enough clearance to pull the pan out.
Unless yours were custom made, the headers are either/or when it comes to auto and manuals . But, that doesn't mean there won't be fitment issues. The manufacturers made them to fit as many years and applications as possible. This means moving or denting a tube now and again to make them work...
Jared, In your shoes, I would just do a trans that already had OD like a Richmond 5 speed or T-65 6 speed. Then something on the order of 3.55 gears would be in order.
You may want to put 12 volts to the posts on the side of the trans to make sure the solenoids are working. The rebuild is not that different from a TH 400. A shop that id good with the TH 400 should have no issue with the ST 400. The converter is the thing you want to watch out for if...
