Hey all....I have just aquired a 61 Lark VIII,259, automatic.
I have done some searching and found out the 2nd gear start is normal. This I do not care for. I see Sasco sells a valvebody for $350.......Man I could rebuild a fresh TH350 for that!.........However, mine flairs up on take off in D. 1st and R are nice and tight. Even when manually shifting from 1st to 2nd it flairs up, or when just taking off from a stop in D it flairs up.....then starts rolling as the rpms come up and fully engages. I don't believe the t-v to be adjusted perfectly as it doesn't kickdown when floored, but it does considerably raise the shift point with increased throttle. This should not affect even an easy takeoff in D though.
I know there are 2 bands that require adjustment, and that I believe the rear band is for 1st and R. The other one does hold in 2nd but I can't find any info on what it does. Could the band cause the 2nd gear slip?
I know on the gm transmissions the 2nd gear band is only applied to provide engine braking. So it would not effect engagement. But I don't know if thats the case on the FOM.....
I come from modding just about everything I have owned and I would like to keep this stock as a driver since it is a V8 car.
I have a 496ci BB chevelle that I drag race, and don't want to turn this car into a big project.
Are there any tips on getting a little more power out of these things? Does dual exhaust help?
Converting to the pertronix ign?
Is there an approximate timing # in degrees that these like to run at?
It has the Stromberg WW 2 barrel carb on it. Which is leaking gas so I wil be freshening that, unless there is a better option out there.
The car has 45,000 miles and has been body off restored. The only drawback is it has 4-doors. But it drives SO nice!
I am thinking If I can get this trans working well, I would do a good tuneup, carb rebuild, etc.
Maybe some wheels, and dual exhaust and have a nice driver.
Any info is appreciated...Thanks in advance!
