    How far in the hole 318 pistons

    No, My comparison was to the 48* stocker. Well that's the thing, the V/P at 116 is already at lawnmower status. 51* "only" drops it to 112. Now pump the 8/1 engine up to 10/1 and run the stock cam at 48*Ica, and the pressure goes to 186psi and V/P to 155, now you got a chitload of bottom end...

    How far in the hole 318 pistons

    Wait; 30>50hp from nothing but a cam-change of ; 10* extra intake duration, and 19* additional overlap, that is only meaningful with headers and a free-flowing dual exhaust? I'm just not seeing it unless the rate of lift goes off the chart, or unless you are including the 4bbl, the headers...

    How far in the hole 318 pistons

    They would have to be either down, dished, or some combination, and IIRC, they were at least dished. and none of the five early ones that I have were much out of the holes, at least not nearly .045..... In other words, they may not have been 10.5 engines. More like 10.0 with the thin steel...

    How far in the hole 318 pistons

    Furthermore The factory put these together with 020 steel shim gaskets, with a bore hole suitable for a 318. I can't say exactly how many ccs those were, but I would think that ~4ccs would not be far off. The thinnest I find now are 028s and based of a 340 hole, making them about 6.8cc. The...

    will those chrome reverse clear the calipers?

    [WANTED] V8 K Member - 1974 Plymouth Duster

    More likely is that the 318 has balance issues and a different K will not solve that. Generally the 318s are dead smooth on the hiway, turning around 2200 or less.

    Small Block's

    here are a few; A better rod-oiling system, and more oil to the top-end. Longer lasting bores. No pushrod pinches. Just say no to nylon-tipped sprockets, and single-row chains. NO open chamber heads ever! Variable valve timing, or at least an automatic cam retarder Also rans; More screws to...

    Installing linkage clips

    Just b-a-s-h it! But your Z-bar should be installed at 90* to the car centerline from top view, and parallel to the ground from the rear. Then the downrod from the pedal should go straight thru the center of the oval hole in the firewall, to meet the lever welded to the Z-bar. Finally, the...

    Do I wait for the 5 speed?

    Speaking about many gears; Earlier I ran the A833od with a GearVender behind it and splitting gears, making 7 progressive gears. For a while, I ran it with 4.88s, which, in double over, ran like 2.70s .. But I soon settled on 4.30s, for 65= 1930 rpm. In the end the 13.28 parade gear was too...

    Carb recommendations for my 340

    Gee, I put a lo-compression 318 in my 84 with a TQ on it and with 3.55s she spun 28s for a loooooog way. not bad with 3.23s either. Oh wait I almost forgot the 2800 convertor, lol, lol.

    Do I wait for the 5 speed?

    Depending on your torque output, and specific build; the A/F body A833od unit, a 3+1, is a great option. What I mean is this; the ratios spreads are a little wide, and better suited to engines with a broad flat torque curve. Like low-compression factory engines. As you put more and more cam...

    Carb recommendations for my 340

    I heard that the QJ on the Mopes was due to a TQ availability crises, back in the day. It sorted itself out soon enough and TQs retook their rightful place.

    Carb recommendations for my 340

    I remember seeing those QJs on Mopars, IIRC in the late 70s. As to special linkages, no, just the typical KD stud. I'm notta fan of sticking a TQ on a square bore intake, with an adapter. Thankfully Mopar has a nice cast-iron spreadbore intake, but it is a big-port; and I'm notta fan of...

    Carb recommendations for my 340

    As for QJ versus TQ, on a 340, on the street; Mechanically, I have mixed feelings as to which I prefer. As to appearance, my opinion is that the TQ is way more handsome, and hands down way more intimidating to look at . As to drivability and throttle response around town, I think it's really...

    Carb recommendations for my 340

    On the street; As for size, any 4bbl from 580 to 800 will be fine. the smaller ones are more responsive under 60mph, with street gears. As for easy to work on, it's hard to beat a Holley. As for the hiway, a small spreadbore is the way to go, and with metering rods is even better. Over all...

    Solve the puzzle? Draining converter with Magnum flex plate

    Just so you know, moot now, I have drilled and tapped a few 904 convertors, with no noticeable balance effects; but then, the stock 318LAs only rev to barely 5000 when the valves begin to float. Mine had better springs and went to 5500 but the cam was done by 4500 or so. I just reved it to...

    Header install question

    Criminy, not many years ago, Every fall, I used to take my 367 out, and the trans, and the GVod and the rear pumpkin, and swap in a 318/A904/different gears, no GVod; for the winter in under two short days; drive it in/drive it out. That Barracuda was my DD for six years until my son made me an...

    [FOR SALE] Electric choke TQ

    Is that Chevy arm convertible with parts robbed off another Mopar TQ, or does it have to be de-coupled from the throttle-shaft? or can a guy simply swap in a Mopar baseplate? And Is that choke All-Electric or heated air assist off the exhaust manifold? You got a track-kit to go with that, with...

    86 Black Roller 318, swap/interchange into 72 318

    What's wrong with using the 318 crank that is already in the engine? Even if it's cast, How many broken 318 street-cranks have you ever seen? or heard of?

    14x7 steel wheels with 5x4 bolt pattern

    Let's talk Scrub-radius. If you mount a set of factory-diameter tires on factory wheels, at factory ride height, and if you could draw a line thru the center of the Ball-joints, down to the roadway, and another line thru the center of the tires/wheels, as viewed from the front; then, those two...

    Leaf spring question

    If it's for ride quality; try this; I run 295/50-15s on 10" alloy wheels at 24psi...... and my springs have an extra main leaf, so I can run them with nearly no arch. Rides barely harsher than stock, but totally acceptable, and corners nice too. Oh yeah, I installed some plastic inter-leaf...

    BF Goodrich radial T/A white letters

    Rusty's right, the BFGs have rounded edges, I run my 295s at 22>24 pounds on Tens, which gives me plenty of nice even wear. And contrary to popular opinion, after you get used to how they corner at that pressure, the self-steer is awesome. It's like running a fast-ratio box/arm. and besides...

    BF Goodrich radial T/A white letters

    It's no secret, it's been mentioned a few times. Those are my sliding and drifting tires. But I have other tires on other wheels. At one time I had four sets of tires on the go, plus a brand new set; I always have one new set waiting. New 15 inch tires are too precious to just burn up.

    86 Black Roller 318, swap/interchange into 72 318

    340 Forged cranks are balanced for heavy forged pistons. If you use one with 318 pistons especially hypers, it's gonna cost heavy dollars to balance that up. IIRC those 340 pistons were around 719grams versus like 550 on the stock 318s. Hypers would likely be less. Save some cash, use the 318...

    Brake booster check valve grommet Vacuum Leak - Stalling

    The airleak at the booster grommet may not be 100% of your stalling. What's your idle-timing? If you run too much idle-timing, the throttle will be too far closed at idle, and the transfers will slow right down. Depending on your cam-size, the Transfers could even dry up. Then when you put it in...

    Which pump for 72 small sector 318

    I tried the Thompson first, but it couldn't keep up to my driving style. Next up was the Saginaw, which was the winner.

    BF Goodrich radial T/A white letters

    I have not seen BFGs with brown letters. In fact; the 235s on the front of my Barracuda are about 20 years old, and NOT brown. and the 295s on the back are pretty old too, and not brown either. The car is always parked outside, but usually in the shade. But, hey, I live in Canada up near the...
