    1965 Valiant LS Build

    I'm friends with that guy on FB, to his credit he still loves ICE-powered vehicles and is in no way an "EV-thumper", it was more of an experiment than anything else. I think he owns other classic Mopars that are rip-roaring big piston engine-powered. I agree electric drivetrain takes 90% of...

    1965 Valiant LS Build

    The G3 Hemi is getting there in terms of aftermarket support and versatility (thanks mostly to Holley, definitely not Dodge/Mopar) but it's still quite a bit larger and heavier, probably will never be as versatile as the LS regardless. Nobody really wants to use Mopar transmissions except Mopar...

    1965 Valiant LS Build

    That's all they do. Look at Ford Racing and GMPP for comparison, WAY more support with decent-quality affordable parts for enthusiasts either modifying their cars or swapping older models. GM still makes parts and even crate engines based on the old 350 SBC, Mopar dropped all the SBM/Magnum...

    mini starter diameter compared to earlier starters

    Just spitballing off of memory but I'd say it's about a full inch less in diameter compared to the old gear-reduction ones. It's pretty drastic. Also about 2 inches shorter in length.

    Hedman tight tubes

    I didn't touch the #1 tube, it was only #3 and #5 I had to clearance for the head. I did jack the driver side of the engine up a couple inches, made it a bit easier to get that side in but still not that bad. It honestly looks a lot closer to the steering box than it actually is. I know the...

    Hedman tight tubes

    Tough to get a good underneath shot but hopefully these help... I had to fab my own down pipes using one of those exhaust pipe "donuts" as well as Sandersen offset collectors which reduced the pipe diameter down to 2 1/4". After the downpipes it goes into 2 1/2" duals.

    Hedman tight tubes

    It's not an early A but I have a set on my '70 Duster. The fit of the headers themselves was fine, only had to hammer them on this latest install because the driver side was hitting the truck motor mount bosses on my Magnum block and the bottom edge of the cylinder head (Edelbrocks). The...

    Too many engine choices!

    I would definitely put the 340 in one and play with the /6 multiple carburetion on the other. Try all the manifolds and see what works best; it would be pretty easy, especially on a slant. One thing though, wouldn't that side-draft Weber setup be a bit much for a stock slant (unless you're...

    finally it looks like V-8 time

    I'd strongly recommend a manifold different than the dual-port. At part-throttle the A/F mixture hits some big turbulence after flowing from half an intake port into a full-size head port. I'll admit I've never actually used one but the way it's designed seems to go against everything that's...

    finally it looks like V-8 time

    I'd also recommend against that manifold you pictured. Even though it is technically EFI it isn't that much better than a well-tuned carb AND the throttle body looks like it would flow noticeably less than a typical 4-bbl. carburetor.

    finally it looks like V-8 time

    You could easily (and cheaply) build a 300+ HP 318 with mildly ported 302's, a good cam, Performer or similar dual-plane and 600 cfm carb. A complete EFI Magnum engine does sound attractive but IMO that "beer-barrel" intake is giving up a lot of higher-end power (kinda like the old longhorn...

    Keisler 5-speed conversion on Early A-body: Install has begun

    Oh man, I can't wait to some day get a manual in my Duster. I'm planning to use a hydraulic clutch system like that with a 4-speed.
