    727 Torqueflite transmission cooling 383 71 charger

    In general, put the transmission cooler at the outlet of the radiator's transmission cooler. If the trans cooler is large enough, a stand-alone unit with its own fan works even better. I'm not sure how big is big enough

    LA360 compression

    1. Calculate your static compression sure, don't guess 2. IF it is 8:1, you have 3 options. a. run it at 8:1 b. change heads c. change pistons 3. If the engine isn't balanced (or maybe even if it is) and the short block is fresh, then domed pistons seem like the cheapest...

    Rear main seal question

    Also, check to make sure some of your oil pan bolts aren't bottomed out (need washers) and not sealing the pan gasket. Happened to me....took a year to figure it out

    Clutch linkage

    3, 2, 1 It's basically a series of levers...longer pedal movement, but less force needed

    PVC valve question

    I think you're fine, but you can always replace the PCV valve (cheap). Inside of the PCV valve, there's a little "pintle" which I believe is like a little weight with a point on the bottom. The point blocks a hole on the bottom (near valve cover end of PCV valve). When engine vacuum (or...

    I have no direct experience, but for valve covers and oil pan, would locktight be worth a try?

    318 upgrade power gains?

    As mentioned..... pick taller pistons to keep your compression ratio up since you're boring the block anyway. I've run 340/360 heads on 318's and the motors ran well. No idea on hp numbers though

    Newbie 318 questions

    These guys are all correct. I would suggest, even on a budget, to remove both heads and have a basic valve job, valve guides/seals and resurfacing done (basic head rebuild)...both heads. I would also inspect the camshaft/timing chain/lifters while in there.

    Heads and Headers

    My 2-cents.... I had a similar issue with some iron heads years ago. The machinist used a "super heli coil" (name?) which is about the diameter of a nickel. That black nickel has a threaded hole in it that fits the header bolts/studs.

    Leaf spring wind up

    I've had good luck with those clamps. I prefer adjustable pinion snubbers too if that matters.

    440 Valley Cover for Stock Six Pack (Dual Plane) Intake?

    Well, the one thing it would help is that I wouldn't be using the factory-style valley pan intake gasket...ONLY one pair of paper gaskets to seal the intake. I've done that once in the 80's before aftermarket valley covers were available. I cut up the factory valley pan & used a bunch of RTV...

    Radiator swap with pics

    Yeah, I modified the crap out of my Champion and the fan shroud to make it fit. It works though

    440 cam help

    You'll see a noticeable improvement with 3.91 or 4.10 gears, BUT you basically can't drive on the highway anymore. Sure, you can run 100hp-150hp nitrous on a stock engine

    Anyone have photos of 1974 big block Road Runner pulley setup.

    I'm guessing his A/C compressor is going out and he wants to bypass it like a non-A/C car (?)

    440 cam help

    These guys are asking the right questions. I would be inclined to swap heads instead of the cam.....or more gear if you don't street drive much....or a nitrous system

    Another Rear Main Seal Thread

    FYI - I replaced my rear main seal 3 times only to find out it was 2-3 oil pan bolts bottomed out.... washers fixed it.

    92 Dakota Starter For BB?

    Yep, works better than the original ever did

    Lakewood Bellhousing - What should I Look Out For?

    Make sure the Lakewood has the block plate. I'd also say make sure it has the offset pin for a 10-1/2" clutch, but you don't need it with an 11" clutch

    what gas is better

    That would require a track test....just sayin'

    Help in rebuilding 1970 charger six pac motor

    The 1970 six pack motors use the "big" connecting rods and a special harmonic balancer & weights on the flywheel or torque converter. There's "supposed" to be some other six pack differences, but not visible at all, nor do they add performance. It's "basically" a high performance (aka big rod)...
