All I'm saying is that you can't believe everything you see on E-bag, and that a Slant car with a truck motor in it is still a long way from a clone with a 426 Hemi in it. Merry Christmas!

Is this an engine that would be streetable? I am new to slant 6 power. I am into 62 Valiants and 61-62 Lancers and have always put a V-8 into them but I live close to Merrill Bruner and he has gotten me excited about the slant.....so any help would be appreciated

Well step right up.
I drive it on the street everyday. It just doesn't make the power I thought it should considering the money and time that in it. It is my conculsion that it needs a header and a little headwork finishing to really make it come alive. However it runs pretty good at 15.6 with 3.07 gear and a total car/driver weight of 3400lbs.

Holy Sheep Dip! That's very good for a streetable /6 setup and that weight. Fopar comes pretty close to that, but has to swap to his 4.1x gears to do it.

How's your V8 swap coming along? Got the gas guzzler in there yet?

It's all good.

it`s to bad that i see new slanters reading this mess. all i have to say is i have only worked with 70 and up cars witch are heavier than the older A body. at 3100lbs my first attempt got me into the 16ets and on the street it didn`t make a bit of differents because all you need to do is a good burnout and have the balls to stay in the gas untill the other guy chicken out, there is no timers, no finish line,as long as you hit 120mph and the v8 along side let up first you look good , so all this crap about a slantsix not being worth the time dollar for dollar and is only good for the fact of being different defeats the whole idea behind modifing any engine. i choose a /6 just for the fact that it was all i had to work with but as i witnessed the performance gain with stock rod/ stock crank/ mild over bores/ home grown head modification i saw my street car into the 14.20 range and when it came to building a full tube chassis race car i still keep pace with the same mod that v8 at the same weight were running, at a best of 12.30ets, this is with no power adders, and with power adder the sky is the limit, so to any new or old slant drivers/racers there is happiness on the road with your ride no matter what the performance level, so enjoy it

That time is even lugging around the A/C system. (turned off of course)

I've only got the engine at this point. Plan to do the swap after next summer. Just collecting parts at this time. I have a spare Slant6 to install if the motor sells.
As for fuel mileage, this Hemi is MDS equipt. (Multible Displacement System) There are currently no electronics on the market to run the MDS system, (besides the factory computer) but that should change in the near future. I should get around 18 mpg without it and get a 20-30% bump with it.

It's a junkyard/pulled MDS hemi engine, with full body weight, I assume similar gears you have now 3.07, and some older tranny most likely the 727 I've read to be the most popular. So everyone has been over that you set your goals to high before, however, this time you want to get 20ish MPG AND run 13's.
Well, let's examine some known benchmarks. A SRt-8 charger was running next to my cummins at woodburn cranking 14's, in a motor with showroom miles. Next, a 727 has no overdrive. Last, the automatic that comes in the hemi won't fit in your cuda and you would have to program a side computer to run it. So that leaves a 5-speed from keisler or such. The MDS is good at a balance of power to fuel, but to get anymore performance than the stock 345 you must change out the exhaust valves and compression release, otherwise I've read ZERO hemi's running MDS faster than 15's.
So to wrap it up, have fun, since you didn't listen about buying a crate motor which is NOT a ebay rebuilder. And no I'm not a know it all, however, God gave us two ears, and one mouth to listen twice as much as we talk.

You post is a bit confusing. Could you explain about junkyard engine,full body weight and NOT ebay rebuilder? You seem to be all over the place and I am not completly following you post.

1)Easy, a junkyard engine is nothing compared to a built engine, pretty easily explained. Dropping in an ebay motor that even has 30,xxx miles, is not a crate motor.
2) Full body weight, no fiberglass, no tube chasis. You, like I, have full interior and niceties that make the car a pleasure to drive on the street. No quarter mile cars have A/C, ok that was to easy.
3) ebay engines have already been explained, if I can't see the cylinder bores or look at the miles I wouldn't trust it. I think I read something about you getting it from an engine builder rebuilt. Cool, it's steps towards a crate motor. With new aluminum blocks, I think that reboring is more dangerous than ever, but someone else can correct me on that.
So it's a stock 5.7L hemi behing your 904. Already explained the problem with gears resulting NOT in both 13's and 18-20 MPG. If your lucky you might get one or the other. So have fun, correct me if I'm wrong. I have no loyalty right now to one engine or another, my uncle swears by the 340 and wishes I would stop screwing around and get mine from underneath his workbench. I'm an engineer though who likes playing with engines. The slant is a cheap platform to learn off, which none the less to say is a lot.

I've been following this thread from the beginning, and the thread before that detailing the build. Here's my take on it for what it's worth. Bren had some decent ideas from the beginning but the execution was inadequate. The machine shop made some errors, Bren made some errors. Bren was, at times, hard headed but overall I would say he gave it a fair shot. I believe the motor can be made to run even better but 15s in a 3400 lb car in street trim is nothing to sneeze at. Still, he isn't happy with it and there's no amount of jawing and finger pointing that will make him happy with it. He's decided to scrap the slant and go with a Gen III "Hemi." His car, his money, his choice. Godspeed.

Growing older is unavoidable but growing up is strictly optional.

Ahh..just wanted to be sure I knew that you didn't know what I doing here.
1. There is no junkyard engine or rebuilt crate engine being used. This is a brand new engine that Chrylser would have install into a new 2008 car if there where enough cars made to do so. This is called a production over run. 0 miles on this motor, not "thermal cycled" ect,ect,ect. That takes care of 1,3

On a stock motor alone I'll reach the 13s
Gotta run
PS the slant is not a cheap engine to learn on. A Chevy 350 is.

amen to that. I don't think this is a Truck Motor (although I can see how that's a good line to try'n piss brennan off) and I don't think his car would loose any more value (or gain!) that a '68 charger with a SRT10 in it... or a crate hemi for that sake. I still think that mileage quest doesn't go well with performance quest. But that's me and I have been proven wrong so many times...

I do believe that the power is hiding below that crap head, headers (lack of) and some minor details (A/C not being one of those details) I'd go with 3.31 or 3.23 rear end ratio, P/S P/B and A/C but with a good head and headers. I believe that his short block with the right cam and matching good breathing head would make the difference.

If it were me.....

I would keep the Dutra duals....but I would add a very skookum Y pipe with right sized primaries, muffler and pipe.

Get a Jeffries head on there.

Deck the block to match at 9.5cr

Get the right cam to go with it

Get a method for tuning. This could be Megasquirt or a good dyno tuner....or anyhing in between.


....and Id be happy with the results.



Please note that any hemi installation will also require a method of tuning....and a realistic expectation.
