    Look what I found today, and it’s GREEN

    Very cool! Needs a bunch of work to be "nice". If the price is right grab it. I would have no problem fixing all the mechanicals and pimping it as is. The top appears to be in decent shape considering.

    Sounds like you can make use of it. Nice engine braking coming down the mountain ;-)

    73 Roadrunner gear set

    Define healthy? How much cam and what rpm range? 3.91 gear is a great performance gearset for the track. You need to be able to turn 6000rpm or you will run out of gear in the 1/4 mile with 28" or shorter size tires.

    Give Todd Marsh a call. I'm sure he can answer all your questions.

    What gear and converter will you be running? Street driving or more track ? Do you want rumpity rump or friendly driver? Will that came work? Sure. Will it be fun to drive ? Depends on how tolerant you are. One size smaller would be a much better "street" cam IMO. The XE284 likes 10.-1...

    Oil recommendation

    I have used Valvoline Vr1 and Lucas hotrod oil with no failures.
  7. 496 polara

    What is the right tire pressure?

    30-32 cold would be my starting point. With such a short sidewall they will have a firm ride regardless.

    Estimated 1/4 mile - 71 Roadrunner 340 4 speed

    If you are spinning then getting it to hook is priority number one. No tuning will make much difference until you can hook. Try to find some older experienced hot rod guys who can help you along the way. Get it to hook them worry about more power or better using the power you have.

    Estimated 1/4 mile - 71 Roadrunner 340 4 speed

    Check the basics first. Timing been checked? Spark plugs read? Lean or rich? What rpm are you shifting at? Call me crazy but that setup with 3.55 gears would likely perform better with a performer rpm intake. For a dual purpose drag radials the Nitto 555 drag radials always worked well for...

    What engine is this?

    Intake recommendations for my 73 Road Runner 340

    By all means run the stock one if you want to.It is free,paint it and go. If you ran across a performer or ld340 for a deal then pick one up.It can be painted to look stock. A good performance valve job and some new valve springs if they are old doesn't cost much more than a stock valve...

    You say valve work,what are you doing to it?

    Intake recommendations for my 73 Road Runner 340

    Big thing is if you are running a thermoquad you need a spread bore intake. Edelbrock Performer may be the easiest to find. Make sure the ports are opened up fully to match your heads.

    Which rear end to purchase

    Typically 12.0's With more converter I'm sure it could have run some 11.80's.
  20. 496 polara

    Which rear end to purchase

    Unless you have plans to upgrade your power level or run low gears with slicks and high stall converter on the regular. the 8 3/4 is plenty stout. My 73 Charger was a 4000lb pig with 525hp and 4.10 gears that made many a pass with drag radials and my 8 3/4 never blinked. Dana 60 is buy once...
