    Bang for the Buck Thread

    Save up another $2k and call me in the morning. Seriously tho, I would not piece a stroker together over time. As stated above, a stroker bottom end and stock heads….bad combo. Same the other way around. Make a comprehensive plan as to what you want out of the package, and how to go about...

    How much gain with lower gears?

    In my bone stock GTX, I went from a 3:23 to a 3:91.....no difference! Since then I put in a converter and really lit the car up, but the only time I've had to try it at the track was at the Nats last year and I had a fuel delivery problem that kept me from full power thru the traps!!

    Broken spark plug insulator or loose spark plug wire would be my guess!!

    Same head as above, maybe no freeze plugs in the end caps of the head!

    906 or 452 which is best overall

    906 heads came on just about every RB motor from 68-72, until the 452 was introduced in the cast crank 73 and up era! Of course there were other variations such as the 346 and 250 heads, but all were pretty much the same! As for building motors and all this chest pumping, it doesn't take 20...

    Backfire from exhaust

    Backfiring through the exhaust could be from a broken insulator on a sparkplug. How do I know??? My brother had a 340 Challenger that backfired through the exhaust. Long story short, he changed the timing chain, retimed it, carb checked, ran through a check on everything, still couldn't find the...

    Starting an old engine ....

    Yea, I'm with the bypass the gastank crowd. Disconnect the line running from the tank to the pump and put a hose into a gas can. TYou can always drop the tank later and clean it out with a gallon of muriatic acid and see if it cleans up!! Get it preoiled and you should be fine for an initial...

    what exactly is the point?

    There have been many camshafts put in over the years by just lining up the marks and slipping on the gears. However, when you are putting together a motor, it pays to have all available technology on your side to best optimize your specific application. A degree wheel will insure that your cam...

    Stupid Distributor Questions

    George, I chimed in a while ago and I'm sorry to see that it is not running well, YET!!! I am following along with interest and can offer only my recent experience with my change of distributors. I had a new electronic distributor from a friend and the reluctor went out so I bought the entire...

    how much difference between 3.91 and 4.10

    Allow me to chime in!! I had a 3:23 suregrip in my bone stock 67 GTX 440 auto, and my best time down the 1/4 was 14.06. OK for a bone stocker but I wanted more so I swapped in a set of 3:91's. Guess what!! Except for the time I had to pedal it and might have broke into the 13's, the 3:91's did...

    Stupid Distributor Questions

    Changing to the MoPar performance electronic ignition kit is a pretty straight forward installation. The kit comes with very easy to follow directions and it is just a couple splices away from going right in. The distributor right out of the box is usually close enough to just set and forget...
