FE Technical Forum / Re: Cooling temperatures

Running a 427W in the tight compartment of a 1985 Mustang I found that adding hood louvers made a huge difference in maintaining engine and underhood temps.
I used to run the big electric fan deal but went back to the factory type clutch fan with a slightly more aggressive clutch. With 180 stat it stays in the 170-180 range.
Giving the hot airflow from radiator a path to escape helps greatly.

Does today's pump gas cause engines to run hotter than the leaded gas of 60's thru 1970?

FE Technical Forum / Re: oil catch can
« on: August 10, 2022, 12:46:33 PM »
I run my PCV system with catch can this way....  PCV valve is plugged in front end of  driver's side valve cover and there is a baffle in valve cover there. Hose runs from it  to my 2 stage catch can. 
The vac. feed line runs from base of carb to the oil catch can and there is a filter breather installed in rear of passenger side valve cover providing fresh air draw into the engine.

Air is drawn in at breather and flows thru the crankcase and then oil mist filter out before entering intake manifold. I also use a clear plastic fuel filter in the vac line as a last catch and visible
to see if any oil is getting past the catch can. I drain it about once a month or so based on how much driving is done and might see 2 teaspoons of oil

How did we keep the cool back in 60's-70's with the factory shroud and fan? Seemed to work well enough back then!

Can you degree the cam so the intake valve closes a bit later which would reduce cylinder pressure and octane requirement?

Haven't followed your build but are you running a 445 cube FE in that Mustang?

Yeah I see those flow numbers and that No. 1 is right bad.   Have no idea what mine flows after the work I did to it.  Did you ever run it on an engine to see what it would do?
If you can find your flow numbers after the port work that would be great. Thanks for the reply!

Thanks for the reply Joe and you are the one I need to chat with!   I worked on that runner with the boss intrusion using long shank carbide burr and was able to remove a good bit of it and smooth
it out. Don't really know why it needed to be there with enough thread with out it. Would like to hear what work you did to the manifold and results.
Did you flow the intake before and after port work?  After opening up the plenum bores I went in and opened up,radiused and blended the roof of the runners as best I could.
I run a 1 inch four hole spacer to match under the carbs. From what I have read if you cut down the plenum divider wall the airflow will tend to favor the lower level of the manifold due to air speed.

I wish there was a better taller intake like this to mount Holley carbs in line and maybe one like the 427 Tunnel Wedge but nobody has stepped up to build one....unless you have a Chevy LS engine!
However for street use the Price intake isn't that bad with the cam I'm running.  True my first intake was a Super Victor with 950 Holley which pulls harder at the top but this intake seems to run
 better below 4000 RPM. It will cruise with a 14.4 A/F ratio in 5th gear at 1600 RPM where the Super Vic was not as comfortable and needed a 13.4 A/F minimum.

This Dynojet run back in 2018 with the Price Motorsport intake and the carbs opened up to 650 cfm each. 82F that day with East Coast humidity.

I just like the dual Holley setup....a result of my youth in the 60's!  :)

Wonder if the drop base Chevy 427 air filter assembly would have fit?

Only guy that makes one and where I got mine.    https://www.pricemotorsport.com/ Click on Intake Manifolds.

Here I was opening up the plenum bores to 1.710 and also did other port work.  Runners not big like Super Victor but you can make 550 HP with it.

In the typical 1965 Cobra setup shown here.  Amazing they ran as good as they did! Supposed to be an exact recreation of first Shelby 427 Cobra.

Got it done today. Had to slot or open up the valve cover bolt holes just a bit and now they drop right on and clear the rockers.

The ones for the 351 Windsors punched out to 427 cubes.  Waited a week to get them from Ansen who makes the for Ford.  Go to put them on and
find they hit my roller rockers before the bolt holes come anywhere close to lining up. When you see how they angle the sides in and out for the "look" compared
to my old ones that is why they hit. Damn shame as they really look great!  You would think being a race type tall valve cover they would make them wide enough
to clear roller rocker arms!!

FE Technical Forum / Re: Why didn't Ford use a better camshaft in the 428 SCJ engines?
« on: June 09, 2022, 07:50:02 PM »
Yep something in the 224/230 @ .050 and .500 lift would have made for a strong runner in the 428 SCJ! However it is still impressive that the engine ran well for such short intake duration on the original cam.

I have the original hydraulic cam out of my brother's 1970 Hemicuda. With 10,000 miles on it I set it up in my lathe with a degree wheel and indicator and it checked out at 284 degree at .006 lift and 228 degree at .050 with a 112 LCA and a .470-.480 valve lift depending on true rocker ratio.
