390 pump gas deal... 1976 F100 aka "The Mistress"

[bluef100fe]

Build consists of 4.085 bore, 3.784 stroke,10.6 to 1 TRW flat tops, Hastings rings. C4AE-G heads with my valve job and port work and stock 2.03/1.56 valves. Holley strip dominator intake with some rubbing, 2 inches of carb spacer under the Quick Fuel 800 CFM carb. 14 by 6 air cleaner. Cam is a solid flat tappet from Oregon Cams. Harland Sharp rockers with P.O.P shafts and stands. Header are 2 by 36 with 3.5 collectors. This combo has gone a best of 12.35 @ 106 in my 3900 lb. truck this fall after about 7000 street miles and being bracket raced for one season.

A healthy 390.
No details though?

[bluef100fe]

Sorry I'm trying the Internet Explorer I'm using keeps crashing on this site for some reason. I think I got most of it now.

[ScotiaFE]

Sounds like a solid combo.
I see your oil pressure is steady at 84 psi, which is good.
Which oil pump and spring are you using?
Do you remember your bearing clearances?
Just gleaning data. Thanks.

Cody, are you sure the intake is a Holley STRIP Dominator? I have had Street Dominators, but I didn`t think Holley made any FE Strip Dominators.

Hey Rory, good to see you over here!

I think it must be a Street Dominator, since they never made a Strip Dominator for the FE.  Maybe Cody sent it to Joe Craine for porting and now its a Strip Dominator 

[bluef100fe]

I will take a look at it tonight now I'm second guessing myself. Hey Jay I thought Joe retired?

[jayb]

I think he did, Cody, several months ago.  Great to see you on the board, by the way...

And I'm still kicking myself in the butt for not getting my PI intake to Joe Craine while he was still porting intakes.
GUH!

Guys: I will try to help forum members on a limited basis with intake manifolds, but I am trying to keep it at a minimum.  I still have not gotten to a couple of my own projects.  I have been helping a couple of my old customers with really neat combinations, and it has been fun.(270-280cfm through a 1.94 intake valve.)  If you are not in a hurry, then e-mail me with your need, and I will see what is possible.  Joe-JDC.

Joe,

I emailed you at your ******** at  swbell.net email. Let me know if that's not up to date.
Thank you.

Well you guys are right. It's a street dominator intake.  I'm running a m57hv pump with the supplied spring from melling. Front sump pan with 6 quarts oil. Oil clearances are in the. 0025-.0030 range as I reused the rod and main bearings last time it was apart. Running 5w50 oil. These engine never had that kind of pressure in the truck.  Probably due to low temperatures on the dyno.

I did notice that the water temp was pretty low.
Might have even put the numbers a tad higher if it was a bit warmer.
The oil would have been pretty thick.

Actually, lower water temperatures will result in higher horsepower numbers than higher water temperatures.  The reason is that the lower temps keep the intake charge cooler, and make the engine more volumetrically efficient.  Less heating of the air/fuel charge in the intake tract, basically.  Thicker oil will tend to reduce horsepower, but the affect of the water temperature is much larger than the effect of the oil temperature.  This is why you'll see a lot of racers icing down their intake manifold or flushing the cooling system with cold water before a pass.  If you can manage it, cold water and hot oil will give you the best horsepower numbers on most conventional engines.
