    [WANTED] 73 Dart Sport hood with cutouts for factory hood scoop.

    Do you happen to know anyone coming down to the Daytona Turkey Run (Florida) at the Speedway? I have 1-2 hoods (would need to check condition) and a hole saw that I believe cuts to 4 1/8".

    Help identify these heads

    Good heads. I picked up at least 2 tenths switching from unported 587 heads with 1.88/1.60 valves to unported Indy LAX with 1.92/1.625 valves with 4-5cc smaller chambers. Head prep & the rest of the engine stayed the same.

    Sizing spiral locks

    Spirolox have been .990" for Mopar small block pistons. I'm pretty sure thickness has been .042" or .044" with some manufacturers using 2 per piston and some 4 per piston. But the original manufacturer is the best place to get them from. Always hated trying to take the old ones out.

    3.31” Crankshafts

    I've seen OEM 273 rods run successfully in race applications but the ones Mopar sold through Direct Connection, including their standard size 340/360 version, were forged from 4340 material, like Scat I-beam and many H-beams rods today. Eagle SIR I-beam are made from 5140 material and I'm pretty...

    3.31” Crankshafts

    Thanks. I wasn't sure since (if I remember correctly), forged steel is heavier than cast iron so the crank counterweight would be a factor. May have changed piston weight?

    3.31” Crankshafts

    Some forged pistons, like SRP, are lighter than hypereutectic pistons, at least in 360 applications. A LA 360 with aftermarket I-beams & SRP pistons will take little, if any, mallory metal. But I would give up a little weight and go with Scat I-beam instead of Eagle I-beam because they are...

    Choke Horn Removal

    It seems like the choke tower can create an imbalance in air flow and/or booster signal between the primaries & secondaries. While the difference may be small and obviously works in OEM configuration, forced induction may magnify the situation to an unacceptable level. Calling some turbo...

    Swap meet at Garlits place

    I've been there a few times over the last few years but not last year. For me it was the slowest I've seen in swap meet traffic and it seemed to have less vendors/sellers. May have been due to the 2 recent hurricanes that went through Florida, the economy & elections. I expect next year to pick...

    Which spacer is best?

    Canton Racing has a wide variety of phenolic spacers including tapered 4-hole. I didn't make any comparisons, but the 1" phenolic tapered 4-hole was what I used on my 360 Dart Sport. Better insulating qualities than aluminum with the tapered bores, or whichever style you choose. As with most...

    75 dart sport front bumper interchange

    No, Dart has the wrong contours for the grille because Darts have a more obvious "beak" and do not interchange bracket-wise anyway (early vs late). For both Darts & Dusters, the most obvious external difference is that the later bumpers have extra mounting points near the top on either side of...

    Is/was there ever a 340 Magnum

    Yes, I'm pretty sure you are correct - except I believe that cam was only used in 1968 sticks. May have had a dual point distributor too. But the HP remained the same. They may have mentioned it in the ads but didn't make any comparisons suggesting that one was better/more potent/faster than the...

    Is/was there ever a 340 Magnum

    If OP Brooks James is referring to the actual engine specs.....There was only one version of a 340 for each respective year, no different specs (except 1970 340-6 in T/A and AAR E-bodies). "FOUR BARREL", "MAGNUM", it was all marketing. MAGNUM was a Dodge thing, just like Dodge & Plymouth each...

    Scamp bumper?

    Duster & Dart front bumpers are not the same. Dart Sport has a bigger point or beak. They just both gained the extra license plate carriage bolt locations when they went to the "shock absorber brackets". Dodge Dart Sport can also interchange with Dodge Swinger, Custom, Special & SE as long as...

    Scamp bumper?

    Scamp is a Plymouth so a Duster will work. BUT there is another variable to watch for: Standard vs "shock absorber" style bumper brackets. Chances are that you will have the latter "shock absorber" style brackets, but double check. Those latter bumpers are easily identifiable by 2 extra carriage...

    I also have Ranchos on the rear of my Dart Sport & Aspen Wagon race only with SS springs - RS999116 single adjustable.

    Are leaf springs in the stock location, on 3/4' offset hangers or moved into the frame rails? I got 9" Hoosier slicks + sidewall bulges on a 10" rim to fit nicely in the wheelwell with 3/4" offset hangers. (no mini-tubs) I don't think you'll gain much without moving the springs. Early on I...

    727 yoke play

    Also remember that as the car is launching forward, the engine and trans are getting pulled back against rubber/poly mounts and even motor plates can flex a bit! Better to have a little too much clearance than not enough.

    Flex plate choice ???

    I've broken solid "ears" on the 4 ear SFI Mopar flexplates, but that's after a LOT of racing. I went to B&M solid round with no issues after that. I knew not to use OEM plates with cut-outs and was surprised the solid ear version broke.

    Bumper bracket questions

    1973 Dart Sports had standard brackets front & rear. '72 & earlier brackets & bumpers are different - (i.e.: Demon - straight bumper) Most 1974 Dart Sports had standard front brackets too. 1974 was a "transitional" year so results may vary. 1973 & earlier take the same brackets & bumpers. '73...
