FE Technical Forum / Machined One Piece rocker plate
« on: April 07, 2021, 10:39:07 PM »
I am looking for the post where one of the members posted his rocker stand plate he machined. It's a one piece rocker stand plate that replaces the individual rocker stands.

I thought I had saved the topic, but I can't find it.  Hopefully some one remembers the post ?

Thanks

FE Technical Forum / C8AX-6250D Cam
« on: March 16, 2020, 03:28:31 PM »
All you negative commenting people kill me. Where were all your fine comments when Mike was going to thru the trouble of having these cams ground ??? I am actually kinda disappointed in whats gone on.

Mike did a service for the community it ended being something people wanted for what ever reason, mine was cause it was what was used back in the day, when I was a kid, so I bought one.

So, all of this experience and knowledge on these boards and no one has offered any suggestions or recommendations to help the people who bought these cams for what will help make these cams work.

I have a little hobby engine building back ground, nothing like the big name people here on the Boards, but enough.

So I'll start:
For reference- there was posted recently about an Old School 427 Tunnel Port motor stock bore & stock stroke was just freshened up, and dynoed @ 513 hp.

I am building a 468 4.125 x 4.250, with Blairs Street Pro Ports, with a J Sidewinder Ported & Flowed by JDC with each port flowing over 385 cfm averaged out to 387.95 cfm.

The D cam is just a hair larger than the came I was going to run, with identical opening & closing exhaust specs and it has 9 deg more of int duration and about .015" more lift.

Are there better Heads & Manifolds? SURE Are there better Cams? SURE  But  the question is ? Will this cam work in this engine combo,  I think it will work pretty darn good, and be fun.

« on: December 26, 2018, 03:34:21 PM »
I am thinking of going .927" Pins w/ 150 to 180 walls on my 427 build, with a 4.250" bore.

Anyone seeing issues with this thinking.

FE Technical Forum / Jay's Clear Vaccum Formed Valve Covers
« on: April 11, 2018, 03:17:51 PM »
Checking to see if there is an interest in Jay's Vacuum Form Covers, but ones without any Breathers or Baffles what so ever. I want to be clear, there will no provisions to use any type of Breather in the covers, these will be just plain clear covers.

In my discussion with Jay, I told him I would be using a PCV on the back of my Sidewinder and a fill Tube & Breather cap on the front, so I would have a positive crankcase flow and the covers could have breathers or not, so he said he could do some and just not add breathers.

Now, Jay still intends to provide the clear covers with Breather Caps & Baffles, but not until he is able to work out a Baffle System he is happy with, and no he didn't mention a time frame for that to happen.

So, Jay said he may do a small run of these clear covers without breathers in May, and how many depends on additional interest, he said he was going to see if there was any interest in them at the FE Reunion and said it was ok if I posted about it here. As he has already stated the covers limit which rocker setups can be used with these covers, so keep that in mind.

So, I think the PCV and Fill Tube with a breather will be enough. Actually, I had found a breather cap that has a tube for a hose that I intend to run to the bottom of my air cleaner instead of having the breather cap vent to atmosphere, and even thinking on adding another PCV in line to the air cleaner ? Also, I was thing about an electric Vacuum Pump. I will be running one vacuum pump as it is for my brakes, actually a vacuum tank and a pump for my power bakes, so one more for PCV is an option.

Post interests here, I myself currently want 1 set, so count starts @ 1

Say they Flow:  317cfm at .500 lift and 338cfm at .700 lift and that's out of the box ?

I was researching cranks and found this Sonny Bryant FE 4.250 Stroke crank in this article.

Article about the engine builder:

The crank looks really nice.  2.75 mains & 2.100 BBC rod jrls, and fully counterweighted.

FE Technical Forum / Head Gasket Questions
« on: January 06, 2015, 03:13:44 AM »
Wouldn't I want a head gasket to fit the bore of my block ?

I 've noticed head gaskets for instance for a 390, come with a bore dia. of 4.180", are they produced that way to cover an assortment of bore sizes, like for the 390 to the 428 ?

And gaskets I've seen for the 427, have a bore dia. of 4.400".

Let me take a guess, Tooling Costs, it's cheaper to tool for one gasket that will fit an assortment of bore size than tooling for a number of different bore sizes.

FE Technical Forum / PBG Rod Bolts ?
« on: October 24, 2014, 02:44:31 PM »
I have a set of re-sized FE rods, that have new bolts, and on the heads of the bolts it reads PBG or PDB with the P at one end and the B,G at the corners of the other end of the bolt head, anyone familiar with these bolts ?

I know nothing about these bolts, so unless some one knows anything about them, I will have to swap them out for a known quality fastener, either ARP or SPS bolts and have the big ends resized.

FE Technical Forum / Intake Comparo 427 Dyno Mule
« on: September 27, 2014, 11:56:00 AM »
Hi  jayb

Questions about your 427 Dyno Mule:

How did it hold up with the Honda jrl's, do you remember the oil pressure ? Do you have a number for how many Dyno pulls ? Did you pull it down for inspection afterwards ?

What do you think about the motor endurance wise for a street motor, daily driver ?

I am going to have to start sourcing odds and ends for this motor I am putting together, a flex plate, descent balancer, balancer spacer, oil slinger, wind age tray for a start. The crank shaft parts, I am looking to pick up first so I can send the whole assembly out for balancing.

FE Technical Forum / My 427 Build
« on: November 13, 2013, 02:25:59 PM »
I am finally getting some work done on a long neglected project, my 67 XR7 GT Mercury Cougar, car was park in 84 with a rod nock, I had picked up many years ago a 67 427 SO block to build to go in place of the 390, and I am finally getting around to doing it.

I pretty much want to stay away from chinese parts, so I picked up an early factory steel 427 crank for my build, it came with grooved mains which there is a little bearing issue, this particular crank comes with 2 additional counterweights off the center main, and I had the crank sent to Performance Crankshaft (Adney Brown) to get worked over. 

My side oiler block I just dropped off at Costa Mesa R&D Machine Shop, for a cleaning and initial check up, The block is currently std bore, and would prefer to stay as close as possible to that size.

This build is going to take a while, so I have decided to pull the 390 and throw a crank and a set of rods in to get it running, here are the current eng & car spec's:

 390
 428 SCJ Heads
 Offy Port a Sonic
 Cam: Old Greg Foreman-Gus Davis Grind .612" lift, Dur 312*-258@.050
 2 1/8" Hooker's
 Built C-6, 3,500 Stall
 Locker 4:57

The car was a blast and had less than 500 miles on the engine build before the rod went, probably a spun bearing ?  The rod went during a pass at the drag strip @ 7,000 rpm 2nd gear, with only a 5 quart pan and no oil restrictors in the heads, so I think the all the oil was in the valve covers and the rods were starved for oil ?  I left the headers un-corked and drove it home with the rod-nock.
