Ya, it's not Moparts. I was the one that was asking about your oil return on moparts. The idea of having a small block Hemi is cool. That's why my 354 truck block I'm going to adapt the small block timing cover on it. Since the early Hemi's take the small block timing chain already. Then the 354's h...

Sounds cool, what will this be going in? Will it be a blower application or?

Lee

I can't remember if I've asked this or not. Has anybody had their heads flowed. I would like to know if the 392 heads can achieve 285 CFM once ported? Thanks for your time.

Lee

Really I would think that really comes down to the spring pressure. I would think that it would be cool to run a new Comp cams F.R.L. cams. Which would have serious spring pressures. Cause even if I was run a small one, say under .500 lift it would still need a serious set of springs. Like my newest...

Thanks, sorry it took so long to get back. Ya, I heard or read somewhere that the stock rockers wouldn't take much more over .500 lift. Is there people here that are running more than this with a stock rocker? Thanks for your time.

Lee

I think that any cam company can make what you want, but if your looking for a shelf item probably not. Maybe Crower, but I'm not sure. Sorry I'm not much help.

Lee

How much lift or spring pressure will a stock rocker arms take/handle? Anybody no? Thanks.

Lee

I'm going to try and put my 392 in my 86 two wheel drive Ramcharger or 81 Dodge shortwide. I would think that it would be pretty easy. They are expensive! Trucks have lots or room. Headers aren't available as far as I know. I managed to buy some of the four bolt 2 1/2 in. flanged exhaust manifolds f...

Cool, a little grumpy I take it? That's cool.

Lee

That's awesome. Does he do any dyno time on those motors? Is he winning any? That is way cool.

Lee

Q.E.C. sells one too. It's a horse shoe & a steel design, there is a picture of it in the Early Hemi Manual book. There is a lot of nice ones out on the market.

Lee

7.06 rods? I thought that the 426 Nascar rod was on .100 longer than the stock 440 rod which is 6.7 something putting the Nascar rod around 6.8 something and the 392 being 6.9. Is this not right?

Lee

Man I sure would like to be able to start building my 392. I would like to fuel inject it. Build a good pulling motor for my 86 Ramcharger 2 wheel drive with a 518 behind it. What do you guys think would be a good cam for this application? I want to pull my family and race car with it. Of course I w...

Thanks, 392heminut. That will definitely help when I do my motor.

Lee

Does anybody know what horse and RPM's they'll take before caboom?

Lee

What's that going in? That's cool looking. I whish somebody would start making intakes agian for the older Hemis.

Lee

Chris,
Cool, so you are you running manifolds? Are they the four bolt flange 2.5 outlet ones? I'm going to run a set of those, cause of room in my 86 ramcharger. I was thinking of EFI system also, don't know if I will be able to afford that yet? Sound cool! What you going to put this in?

Lee

First off welcome, though I'm faily new also.
That's awesome, can't wait. What is a EH20 cam? Who makes it and what are the speaks if you don't mind me asking. Have you ported the heads and are they 392 Heads or they low deck heads like from a 354 or the 331 555 heads? Thanks for your time.

Lee

Nobody, has been able to do this? I wish I could afford to do it. I would of liked to of dynoed my 340 to see what it got. I hoping to put it on a rear wheel dyno. Hopefully when I get to be able to build my 392 I can get it done on a engine dyno. I talked to Dulcich about doing a resto to rad on a ...

Where would a person get those by chance? Are you talking about old chiltan books? I realize that you said factory service manuals, but..... Thanks for you guys replies.

Lee

392heminut, That's on the single four barrel motors right? Also they were hydraulics are they not? I wonder what the 10 to 1 motors were? I read that those were also solid lifter motors and I think that I read somewhere that they were real close to having a lift of a 340 which was around .444 I do b...

:o nobody knows? Chrysler didn't document this information? :( I would like to compare numbers on cams when trying to select a cam to be able to come up with a close horse power comparison. I think on one site it showed the 325 horse 392 to have a cam that was .388 at the intake, is this right? That...

Does anybody have the information what the factory cam specks were in all the different 392's that were put in production? Is it documented somewhere? NE57--392--1957--325@4600--430@2800--9.25--4BBL 58N--392--1958-45@4600--450@2800--10.0--4BBL 3NE57--392--1957--375@5200--420@4000--9.25--2-4BBL 58N3-...

To be sure you need to sonic test them. I would say at least .060, but I here of people going .080 to .125 over. I'm not for sure I haven't done any testing or have any expireance (?) with boring on them.

Lee

I guess I'm pretty green here, but I didn't think that they had 392 truck motors. Did they?
