    Standard 383 vs 383 roadrunner engine

    Yeah, that’s what I thought as well. Now go look at the common on-the-shelf pistons available for the 383 today. Yep! None of them come close to the measured 1.932 Compression Distance, at least that I’ve seen. This is why when I build my 383, I’ll be springing for some semi-custom Diamond or...

    Standard 383 vs 383 roadrunner engine

    Sure I can help. The guy with the 383 info is moparts.com user: JohnRR I don't have the links on hand at the moment but I saved some of his comments on the topic as follows: "It's a warmed up number, the real factory compression ratio was 9.2 at best. To clear up a few things, that have...

    Standard 383 vs 383 roadrunner engine

    True, but the advertised horsepower and and compression ratio ratings are not exactly the same thing. Remember, the base 383 Road Runner was marketed primary to the younger folks on a budget during the golden era of drag racing. Folks wanted to know they had a solid foundation for day-two race...

    Standard 383 vs 383 roadrunner engine

    You'd have to ask old Chrysler that. I'd assume the reason was because it was the height the horsepower wars so fudging the numbers was advantageous for sales.

    Standard 383 vs 383 roadrunner engine

    I was considering a similar idea with mothballing my numbers matching 383 and building an alternate 383 for my road runner. Ultimately I decided against it. If I don't put the numbers matching engine back in now, if the engine isn't bolted to the car, there is a chance it might not ever happen...

    Standard 383 vs 383 roadrunner engine

    This topic has been discused at length over at moparts. The factory compression rating was wildly optimistic. A 68-69 383HP was in reality around 9.2:1. A non-HP down in the 8s. This is one reason that if one isn't attentive to this and stabs in a popular oversized cam; the performance becomes...

    I've been wondering what's a good source for correct VIN rivets?

    Got my wheels back from Sandblast today.

    Oh cool! Back on topic. The rims will be painted F5 green and topped off with "Plymouth Division" dog dishes, which I have on hand as well.

    Got my wheels back from Sandblast today.

    Oh! And the other observation I made when I had my 68 Charger, I ran the tried and true 275/60R15 meats on it with 3.23 Sure Grip. Well, when I went to get the body work done I put the 14x6 70s Rally Wheels back on that cam on the car when I bought it. I was amazed at how ditching the big rubber...

    Got my wheels back from Sandblast today.

    The Cragars pictured are my Father's. They are currently on his 62 Dart and look great. I like Cragars too and used to have a set on my 68 Charger. However, site member, pinkpanthr, literally gave me a set of the pictured factory correct Motor City 14x5.5 Steelies for nothing more than shipping...

    Got my wheels back from Sandblast today.

    I'm happy my date codes came out well even though they are not exactly the right ones for my car. Nonetheless, I will hopefully get them in primer tonight. Fingers crossed.

    She's back safe and sound! And after about 5 hours of clean up it looked like this -> Roof turned out good! Wasn't entirely expecting this, but hey nothing time and money can't solve-> In the morning, we're spraying everything throughout with Rust Proof M/D. I'm told it's awesome stuff...

    Media Blast Time!

    There she is. After 15-years the bird is out of my possession as it is away for an overnight stay at the media blasters. So I'm naturally a little anxious over it. It's not the better part of town, but not much left on the car for the taking either. Anyway, they're not blasting the whole car...

    Dash paint

    Now there's a thought. I just looked around the website. When I get closer I'll give them a call. Did you strip or blast the old paint on those dashes? Mine has some slight surface rust in a few areas.
