"POWER NATION" slant six build

i tell you what, for being a 'slant' guy, you have talked trash on that motor more than any other mopar guy i've ever seen. Has it ever occurred to you that the people making 'only' 300 horse have successfully increased their power by more than double? Please, find me someone who has a 250+ horse slant and doesn't absolutely love it. Now that i'm aware of what 'significant' power is, i'll inform guys with 550 horse 340s that they ain't got squat.

I don't know what you're referring to when you say, "you have talked trash on that motor more than any other mopar guy i've ever seen."
If "talking trash" to you, is saying things of a critical nature, then I may be guilty, because as the saying goes, "you can't make an omlet without breaking a few eggs." if my pointing out the slant six's Achilles Heel, a performance-killing "feature" that prevents it from ever making good power naturally-aspirated, then i am guilty. Everybody who attempts to "massage" one of these engines for better power output, really needs to realize that the cylinder head, a totally irreplaceable part since no one has ever produced any other heads (except for a few hard-to-access Argentinan $$$$$ examples,) which breathe well enough to make much over 300 hp, n/a.

It is a big job, and costs a significant amount of money to buy and install all the necessary parts to build a fully-modified slant six without some form of power adder.

The problem is, as I have said, the fact that the head was originally designed for the 170 motor, and was never upgraded with regards to flow-capability... EVER. So, we are stuck with (225cid,) a motor with 39 cubic inch cylinders with tiny valves and ports, and a breathing capability to match. The small-block Chevy V-8 (1967-'68 z-28 302cid) is a case in point; it also has 39 cubic inches per cylinder, but with much larger 2.02"/1.6" diameter valves, vs. Our 1.625" intake and 1.355" exhaust (which can effectively, be enlarged to 1.7" and 1.5"...) are better, but nowhere near the breathing capability of the brand-x. The 302 chevys that are ported show flow nearing 280cfm on the intakes, whereas our "leaning tower of power" ported heads might muster 220... See the problem?

If you can be happy with the kind of reduced expectations (250-275hp) that that "strangulated" flow results in, then a naturally aspirated slant six will probably work okay for you, and you can avoid the extra expense and time (and, education,) required to achieve the significantly higher numbers afforded by a forced induction setup...

Or, you can use the stock engine, stock reciprocating assembly, at least, never pull the head, and bolt on a low-boost (10psi?) turbo setup, and maybe spend even less money than a naturally-aspirated engine for the same output (275hp?)

You pays your money, and you takes your choice... But, you need to know the whys and wherefores, going in... So, you can make an informed decision.

So much for the trash talk...


i'd hate to know the price of a legitimate bolt on turbo kit for a slant.

might be expensive... Might not; I would think it might depend on the projected output; 300 or 500 hp... Lots of expensive parts for the high-horsepower motor (arp studs, forged internals, etc...)

But, the slant six with forced induction needs some "ink"..... Its potential is unknown to 99% of the guys who might build one, if they knew.


Power nation has the ethical responsibility to educate its viewership on that issue... And, they make their living doing that sort of thing, so, why should they not???

I can't see any legitimate reason...
