HOW TO: FIX THE DODGE SLANT 6 (WHAT BROKE?)

THE OTHER GUYS-DODGE SLANT 6, DIAGNOSE AND REPAIR-WHAT HAPPENS WHEN YOUR SLANT 6 HAS ONLY 5 GOOD HOLES? AFTER ARRIVING AT WESTECH WITH A FRESH (MEANING FREE AND USED) 225 (SUPER SIX) SLANT 6, I DISCOVERED I ONLY HAD A SLANT 5. THERE WAS ZERO COMPRESSION IN 1 CYLINDER. CHECK OUT HOW I DISCOVERED WHAT WAS WRONG AND HOW WE PLAN TO FIX IT! WE NEED 6 GOOD HOLES TO START TESTING.

I was daily-ing a VC Valiant 225 with four barrel and long runner manifolds till recently - and swapped to twin 2bbls when I pulled the head to start matching ports on the HyperPak clone. Now with all the 2020/2021 restrictions, the daily is a Voyager and I'm wondering, will a Jeep 3.8 fit in the VC?

I am so glad you’re doing this, my grandfather passed down a 84 dodge he bought new and it has a 225 slant 6 in it. I got it and wanted more so I fabbed mounts from a factory ls mount and some solid dodge mounts and put a 5.3/4l60 in it. I almost had it done and decided it took to much away from the truck and I wanted the original slant 6 to stay so I pulled the ls out and right now the slant 6 is sitting in the engine bay but haven’t finished bolting it back in. I’m definitely planning on going to a power adder.

from the looks of the exhaust valves, I'd take a really close look at the condition of the exhaust manifold. They're notorious for cracking (early ones are better) and judging by the looks of yours, I'd bet money on a cracked manifold or leaking flange gasket.

[@oldtanker4860]

I learned how to wrench on cars working on a slant 6. Those are great engines with good longevity. You darn near have to beat them to death with a sledgehammer to make them quit. I still (after 60 years) have a lot of affection for early mopar cars. I am looking forward to see what you do to that little mill. I assume it's a 225 CI. They also made a 170 CI slant 6 for smaller cars like the old Dodge Lancer (60 & 61). Learning to work on stuff like the slant 6 led me eventually to get my Air Frame and Power Plant license to work on small aircraft as my 3rd and final career.

Late model head to get rid of the spark plug tubes and also have hardened seats for unleaded gas. 340 vavle springs and the Mopar (Crane) .460 lift solid cam. Accel Super Coil, Offy 4 barrel manifold with a Holley 600. Mopar 6 into 1 header, single 3" exhaust through a Flowmaster muffler.

[@CarsandCats]

Was that a leaded motor running on unleaded fuel so it beat the exhaust seat out of it? Sure looks like it.

[@1575murray]

I don't think so. By the time the Super Six was introduced in the USA all cars had to run on unleaded fuel because they were equipped with catalytic converters. Chrysler had offered the 2 barrel version for export but did not offer it in the US until the late 1970s or early 1980s because they preferred to sell the 318 V8 to those who needed more horsepower than the Slant Six could deliver.

[@corvettejohn4507]

@@1575murray All US cars made starting for the '73 model year had to have an EGR valve to reduce NOX emissions. I do not see an EGR valve on this engine. Maybe somebody put a '77 and later Super Six intake, carb, and air cleaner on an older Slant Six?

[@fustyblatherskite2142]

Chrysler and other auto companies induction hardened valve seats to make them last when lead was removed from gasoline. This head should have had hardened seats because only one seat was damaged. Induction hardening valve seats was only a surface treatment and after about 45 years of service, I do not think it would be unexpected for this process to start to fail.

@@fustyblatherskite2142 You are correct. Actually this started a year or two before unleaded gas became mandatory in 1975. Anything can happen on engines that are this old.

[@PiDsPagePrototypes]

Milling - IIRC, 120 thou is the heads limit, 90 thou on the block, and if you do, watch the the cam lift to make sure minimum .050 between open valve and piston at TDC. Parts - Clifford Repro HyperPak, Pacemaker tuned headers, Cox Bros make roller rockers for slants, and there's good pistons about. Someone was doing seven inch H-beam rods too for a while, which is the whole 198 rods in 225 block to bring the pistons up higher.

[@paintnamer6403]

The Super Six 2bbl intakes can be two piece die cast aluminum top and bottom and what looks like resistance welded or the cast aluminum like featured on this engine. I cut the exhaust manifold outlet off and welded a 2 1/2 inch flange. This also isolated the intake from the exhaust manifold as well as having a 2 1/2 inch exhaust and that gave a seat of the pants feel increase in power. '74 Duster 904 with 2.71 gears.

[@hyperluminalreality1]

Slant 6 is an odd duck. Chrysler leaned the engine over to clear low hood lines. Only reason. Then they put the water pump on the side to shorten the engine for styling fit.

Bolting the early '80's Buick 3.8 draw-thru turbo setup on a stock compression Slanr 6 was claimed to double the power. Between milling everything and the big cam & turbo installs this might be a 'Reycling Yard' approach. Thanks for building a Slant 6.

[@jackdale9831]

use the head as a mold in sand, and then aluminum-cast the head. Once its aluminum, then CROSS-flow it, ripping-out the distributor from the block and putting coils on each plug. The "slant" should cover a cross-flow header dumping straight down, but SPLIT, so you can have true duals, 1 per 3 cylinders, or have each 3 dumping directly into one of TWO turbos, so you can get 750Hp out of your "tower!" Each 3-fed-into-ONE of two turbos'll FEED lots of fuel & air into the OTHER 3 cylinders, so the OUTput from 1 group of 3 cylinders feeds the INPUT of the Next 3. The Output of the last 3, would, of course, feed the INPUT of the 1st 3. Richard, back in the 70s 6-cylinder stock cars used to make 450-500+ horsepower, full-race. Although Inline sixers are not raced before the V-8s {--that I know of}, anymore, WHY can't we almost duplicate the 4L Aussie-Ford "Barra" which can make 1100Hp? I feel you definitely can get 750+ Hp out of your tower, and it will NOT have to be built "full-race, but will be "streetable." Aussie-Mopar had a "Hemi" on some mid-70s 6 cylinders, although they were NOT "slanters". Could an Aussie-Hemi-inline 6 head { head done/cast in alloy }, be PUT on a slanter-block? WHY hot-rod with "Australian parts"? Well shortly, folks can 3-D those parts and better, so if you want, show us what COULD be done. You should REALLY "Blow our minds" and 3-D Aston-Martin DB-6,{--the more popular model made after Aston quit making the Bond-made-famous DB-5} alloy 6-cylinder heads, or TVR would make their own DOHC straight-6 via copying/cutting-up 4-valve Suzuki motorcycle heads from Suzuki motorcycle 4 cylinders to "work" on a 4L DOHC inline 6 of TVR's own, or maybe Aussie-Mopar had a DOHC head to run against the "Barra", or, 3-D the 3.5L-4L Maserati-alloy DOHC head{--from the 40s - the 60s } to fit, perfectly, on a "slant"-6 alloy block. I'll BET there are several 3-D Replicator firms that would WANT you to "3-D" hot-rod parts on your show, and that'd put your GREAT Videos WAY beyond what anyone Else is doing, but that'd Just like you, Richard,--you're Not going to do what everybody ELSE is doing,--you're BETTER than that,--you're "Da BEST!" =

SAND CAST MY OWN HEAD?

[@brocluno01]

Looking at the combustion chamber shape, there is no real quench. So zero decking does not really help much ... Yes, compression does help for sure, but taking enough metal off the deck to get to zero with OEM pistons is kinda chasing a ghost ... Better to go aftermarket pistons and leave the deck thick enough to hold the bolts for boost ... The 225 is still a small engine. Almost wish you could grab one of their (Mopar's) big flathead six's like the original 413 twin carb truck motor and do the same to it 🙃

[@PiDsPagePrototypes]

"Stop when we see the problem,.." Exhaust on number five should not be covered in oil, and the front three have been running lean, all thee need new seats, so might as well do the whole head. It's always a laugh to watch first timers go to lift the head off a Slant - done it enough to use an engine crane :D Now it's apart, can I suggest the Clifford Performance Reproduction HyperPak inlet manifold, and the Pacemaker 'Tuned Length' extractors. Yes, you can skim the head and the block, bore it, offset grind it, add a cam,... but none of that matters as much as making it breathe.
