all that is still on the shelf in MN still is the january issue with the calendar in it, can't find the february issue yet. I have in my collection a few from each magazine (mopar action and mopar muscle) of various slant six articles, most are pretty ho-hum deals, but a few are pretty good. I still have a few "high performance mopar" and "chrysler car enthusiast" mags too. |

I think that is Romeo Furio's newest race motor. It made 320 hp with EFI and without nitros. The article suggested that about 20 hp came from the use of EFI due to improved fuel distribution. |

Although I was glad to see a new article on a Slant Six build-up in a major magazine. I was dissapointed it had parts that we can't afford or come by easily (custom pistons, custom rods). I would have prefered it was a build-up of stuff we could buy. Sort of a formula we could follow from the big boys.  bwhitejr |

Quote: Mopar Action has done several articles on cool Slant racecars, such as Rodney Hargis, Meril Bruner, and Charles Myers. Not for a while, but still... They should really do one on the Drakes' Simca.
mopar action is definitely interested in the simca, they just need high quality pics and a few specs. i'm sure they might cover a non-race slant as well, as long as it's something cool and pretty like al t.'s "big red" or a-team's "we haul." Lou -james |

i saw this was a long rod 225. the rods they used were 7.3(!) inches. did they do that so they could use a smaller(lighter) piston? they said they shaved 100 grams off. zedpapa |

In the article they mentioned that the slant six has a stock compression ratio of 7.5 to 1. That can't be right. I thought they had at least 8 to 1. |

I was surprised at the lack of back-up detail and the number of typos. Maybe they were in a hurry? Maybe that is the audience they appeal to? bwhitejr |

Who has the products needed to rebuild and update a mildly average 225 Slant 6 in a 1978 Dodge D100 Custom pickup? Where can one find the needed items for such a build? And how much HP can be pulled out of that type of motor without making it for race only. I want daily driver and road warrior all in one. signed matamor |

The parts are readily available. http://www.cliffordperformance.com http://www.pawengineparts.com http://www.summitracing.com http://www.compcams.com I am in the tuning phase of my build-up. I was very careful to pick a cam that was streetable. I think I made the right choice. bwhitejr |

Hey guys. Don't beat me up - I'm a new member. But I had to respond, since I'm the guy that built that motor for Romeo. First: * Why didn't we post prices for the custom stuff? The original article was going to have prices but we felt that since this was a "one off" project, why show prices that may turn people off. After all, aluminum rods are strickly for racing and these were expensive parts at $100 per rod. * Did we really use a 7.3" rod? Yes. The extra rod length was a result of the desire to move the wrist pin as far up in the piston as we could without hitting the oil ring. That makes the piston lighter. * What did it cost? This engine ran $10K+. But there was A LOT of head work done. Angie put in almost a full week on that head. I have since quoted several other engines like this one, only without the custom aluminum rods and offset grinding of the crank. They ended up at about $8K. |

As a general rule most of the guys are achieving 200cfm around .500 lift and the heads typically stall from there on up. What did the flow numbers look like in the .200 - .400 lift range? Also who made the fuel rail for the motor? Tom |

Thanks for posting Rich! Realistically, 10 grand for a professionally built motor w/ aluminum rods and EFI is pretty respectable. As Tom said, can you fill us in on the flow numbers? Mike J and I had a pretty good discussion when I was out there a couple weeks ago about how easy it is to kill flow above .400" lift.  Dennis |

Tom and Dennis You are correct that the head started to flatten after .500 lift. But this is normal, and you should also consider the percentage Intake to Exhaust - not just flow. We have seen "hogged out" ports that didn't do much for performance because there was no swirl. I leave the head science up to Angie because she's been doing heads for so many years. Anyway - here are the actual numbers: Lift Int Exh % .2 136 110 81 .3 181 144 80 .4 187 150 80 .5 195 156 80 .6 201 161 78 I did the fuel rail. It's really quite easy because you can just buy the fuel rail. Then thread the ends, machine holes for the injector o-rings, and weld on standoffs. It's timing consuming, but I've done a lot worse. You should see the Hilborn manifold I did that's on our web site: www.moparengineswest.com THAT was tough... |
