    Shock absorber opinion

    Or you can get Bilsteins from Firm Feel for about 50% of what a set is costing on eBey: '62-'76 A-Body Front Bilstein Shocks They also look more correct than what's being offered on eBey: 60-76 Mopar A, 70-74 E/62-72 Dodge B Body Bilstein Front & Rear Shocks | eBay

    Shock absorber opinion

    I did a write up on KYBs over on the corner-carvers forum about 15 years ago, AFAIK nothing has changed since then, I do not like them: 'Good' Shock Tech Copy paste of the original text: "As promised. <RANT> Back when I was much younger (25 or so ) I bought a set of KYB shocks for my ’66...

    350 HP 318 Build

    Meh, locally (DC area) a engine freshen-up, with a cam & intake change by a good shop was running around $8K the last time I did it (over 10 years ago). A complete. run-in engine making over 1 HP per cube from just outside NYC for $10K doesn't seem too bad to me.

    Are all 273 V8's the same?

    Yep, My point was, I was wondering which cam was in those flat-top blocks: Std. 273 2 Brl (8.8:1): Valve Lift: 0.395" 0.395" Duration: 240ø 240ø Opens: 14ø BTDC 58ø BBDC Closes: 46ø ABDC 2ø...

    Are all 273 V8's the same?

    I've had 3 273 Commando's apart, a '65, '66 (out of my Formula S), and a '67, all three had the same bank specific, above the deck, pop-up pistons. I suspect when we see the flat tops appearing, in 273 cars, and keeping in mind how these cars may have been operated by their original owners, we...

    273 piston options

    So, BID they shifted D-Darts at 7000+ and were turning 8000+ in the traps, but that's drag racing only, and not high mileage hoonage, the stock rods and heavy-ish 10.5:1 pop-ups were the limiting factor; the the forged 273 crank is reputed to be good for regular use spinning to 8300 max, but the...

    I've seen A LOT of posts about making HP with a 318-So why is it so ???

    Okay, I''l chime in... As to why a 318, I vintage road race and have a rule book I have to follow: https://svra.com/wp-content/uploads/2013/02/Chrysler_Corp-MoPar_64-66.pdf For me there is a budget, but part of the considerations are operating costs and rebuild frequency. So while I built...

    Vintage road racer Dart '66

    Well I happen to know that Jari has dug himself out of the snow and is headed to the track shortly with a fresh 273 stuffed under his Dart's hood. In the meantime I've already gotten my first two race weekends in First down at VIR for an SCCA Regional Club Racing double (in a 1980 Pinto, Yeah I...

    Fiberglass Hoods and Body Panels

    Really can't help you there, I have only dealt with VFN, and the various other fiberglass component manufactures I've bought from over the years, by phone, I've never actually gotten to watch them making stuff.

    Goodbye Crane Flat Tappet. I hardly knew ye.

    Yep all flat tappet cams need a high zinc (ZDDP) oil to live long & prosper. There was a discussion of oil formulation recently on a vintage road racing mailing list I belong to (from various posts): ... Brad penn 20/50 synthetic blend PPM zinc 1500z PPM phos 1400P...

    Fiberglass Hoods and Body Panels

    I've had good luck with VFN's parts pretty much dropping into place, but I've only had the 3 hoods and one front bumper (also on the Dart) from them, the vintage road racing rules don't allow fiberglass fenders. The fiber glass racing apirn I bought for my'66 Mustang from Maier Racing 30 years...

    Fiberglass Hoods and Body Panels

    Hi MuuMuu101. I suspect they lay up the bracing separately then bond it on with resin as a final step in production. Judging from the level of abuse the previous took while refusing to fall completely apart, I'd guess they lay down a thick coat of mat black gel-cote followed by 3 layers -...

    Fiberglass Hoods and Body Panels

    So here is what the underside of a VFN pin-on hood for a '66 Dart looks like: You can see I've added some bracing and doubled up the center two hood pin hole reinforcing plates: And I had to move the center two pins forward 5" from where I had them on the previous hood: The...

    273 Comando Head ??

    Hi TerraBella, 2465315 is the correct casting number for all '64 & '65 273 heads. Note that the only difference between the Commando and regular 273 head is the valve springs. Here's what I have for production LA heads trough '86 or so: LA Small Block Cylinder Head Casting Numbers and...

    904 help

    Thanks for that I was indeed looking for the snout size too, but I also wanted a definitive answer on the correct ID on the crank. Based upon the options I've found and the below snout diminutions provided by Fishy68, those values are probably: 1.850" for 68 & later 1.565" for 67 &...

    I would but I'm doing this without access to any of the parts involved (i.e., long distance). These should be standard spec's that are easy to look up, but I guess my Google Fu is weak on this subject.

    904 help

    Hi, I'm bringing this back from the dead because I'd like to make sure I'm getting accurate information and the sources on this and the slant six board have some disagreement. My brother has a '70 Valiant that we're putting a '64 \6 into with the existing A904 auto. This means interfacing...

    Will my hood pins be enough?

    Finished the hood fitment this past Sunday. Installed the leading edge trim with a piece of 1/16" wall aluminum angle stock backing it up and two short pieces tying the front of the hood to the underside of the outboard hood pin reinforcing plates: If this doesn't keep the hood...

    Will my hood pins be enough?

    I'm using a race weight hood on my '66 Dart and nailing down the front 8" has been problematic. Above about 134 it would start to flutter with 4 pins across the radiator support and interim measures involving HD zip ties eventually failed leading to the installation of a new hood. This time...

    I Finished fitting the Zebra's ('66 Dart) new fiberglass hood this afternoon. Two fewer hood pins than before, but they are better positioned to keep it nailed down at 140+. Need to add some bracing under the hood, install the leading edge trim strip, and apply some paint, but I have some...

    1966 Barracuda "car ****"

    On engine parts, the after market 318/340 4340 Scat cranks in 3.31" stroke are a direct replacement for the 273 crank. It looks like Egge's website has forgotten about the 273, they used to make Commando pistons. But there are plenty of manufacturers that will tool up sets of custom forgings...

    Quick Release Steering Wheel in 65 Dart GT

    Hi Dibbons, On the street they certainly serve as a theft deterrent (as long as you take it with you or at least put it in the trunk; otherwise it's more of a theft opportunity), however the main benefit of a detachable wheel is to make getting in (and especially) getting out of the car easier...

    273 hop up help..manifold carb etc!

    Exactly. Any SB manifold will bolt up to a '66 and later 273, but the 273s all came with small port heads, just like a 318. So for a '66 and later 273, just order or shop for a 318 manifold. The non-EGR Performer is probably your best choice, and I found it worked great with headers and a...

    Why are 318's low HP and torque?

    So, yeah, the 318 was a low output DD work horse for nearly all of it's production run. Even the '80s Police version was an open chamber 87 octane burning taxi motor with a 4 barrel and 1.88/1.6" valves. There is the unicorn '66 318X described in the '66 Barracuda GT FIA Homologation paper...

    Why are 318's low HP and torque?

    Well this is probably too late to help, but why ever use stock smog era pistons in any 318 rebuild? The earlier style KBs are a lot closer to 0" deck height with only a surface cut, leaving a lot more meat for a stable cylinder head mating surface and eliminating the need for intake milling to...
