| Post subject: | Power Boost for less than $1000 |
I have a 1973 Plymouth Duster. The drivetrain is all stock and I am looking to boost the power. I just want to be able to turn the tires over at will. It is a 225 slat 6 with 3 on the tree. I am looking for a way to beef up the motor for less than $1000 (getting married soon) any ideas or recomendations? Thanks |

Welcome... Do you know the rear end's gear ratio? The 3-speed is a handycap, you would have alot more fun if you change it to a 4-on-the-floor (833) transmission. Have you done a tune-up and valve adjustment? Fast distributor advance can really help. Does the car have anti-sway bars? Do you like a car that corners well? After the above, a "Super Six" 2 bbl and improved exhaust flow would be good "power improvements". DD |

Im not very mechanically inclined so I'm not sure whats all been done, I know its been tuned up. I've had the car for about 7 years and put about 10,000 miles on it. How much would a super 6 upgrade cost me and could I get by with the 3 speed? How can I tell what rear end I have? |

The three speed should get you by, I eventually switched to the four speed overdrive unit. The two barrel won't cost much to convert over, look on e-bay and it should cost around 150 for the whole procedure. I just sold my last one to Steph, so can't help you to much there. Assuming your not to mechanically inlcined does that mean you don't have tools? I would look at pulling the radiator and switching out to a more aggressive cam, have your head shaved, get a good ignition and headers and your money should be spent. Take care and good luck! PS welcome to the board! |

3 on the tree sucks. Eventually that linkage will give you lots of problems. There is no way to mount a floor shifter with that tranny AFAIK. Just pulled mine out. Another type 3 speed should have the mounts. If you wanna teurn over the tires? Put your foot half way to the floor and side step the clutch

FYI: you have an automatic on the column, not 3 on the tree.

A good torque convertor woudl help a lot. Also I think pulling the head and milling it .100, a new cam (keep it small) and 2 1/4 exhaust with a good muffler would be the best way to go. These little things can transform a slant six. Take your time and find a super six on a old car somehwere cheap and forget E-bay. At this piont, you will have spent your money. When you have the head milled you want them to do a angled valve job also. You can tune your factory carb and get a lot out of it untill you find a SS. Also tune the distributor curve ( both cheap upgrades). The exhaust. the head work, and the convertor are the things that will make the most diff. Jess |

.... And a lower rear end gear ratio, especially if the car currently has a 2.76 ratio in it. DD |

If you have a 2.76 gear ratio, do a search on "engine builds" and look for mine on "torque and mileage build". I have an automatic also plus a 8 3/4 posi-traction rear end with P235 tires. I can break the tires loose at will.It may be possible to recurve your distributor to get some of the punch your looking for and a comprehensive tune up. You will have to do some research and good planning to maximize the $1000 budget. Knowing the condition of your motor and the parts that are on it will go a long way in putting a good plan together. If you can't find the build sheet and tuning instructions, send me your email. |
