I've had these items just show up at my door. Heads are the NHRA legal casting CNCed Edelbrock Pro Ports, with stock location exh. Shock Towers made it necessary to go with stock location exh, due to how tight the 2 1/8" adjustable headers were, I couldn't take the chance with having the headers re-flanged, then dealing with fitment issues.

Then I had my "J" Sidewinder matched ported

Flow numbers @ .600" lift cam, which is what I am running: 330 Int & 232 exh with no pipe.

Intake valve 2.200 BP spec Ferrea
Exh. valve 1.650 BP spec Ferrea

There's this guy on one of the Ford Forums that has a program that from engine and car spec's, allows the program with a fair degree of accuracy
to determine an engines Torque & HP and how the car would run in the 1/8 & 1/4 mile, including a 60 ft.

Spec's: 67 Cougar, C6 3500 stall, 4:57 locker
427 @ 429 ci. flat tops @ 10.5 CR with Blair's Pro Ports, matched ported Sidewinder with an 850 Holley
Crower cam: 604/618 lift & 263/272 @ .050", with 108 LS - 104 IC
Exhaust 2 1/8 adjustable Hookers
Engine & Car Ratings:

New Year's Update:

Still slowly collecting parts for the engine build as funds allow. I went with a Canton Aluminum 8 Quart Road Race pan with the needed pickup, and a POP'S Blueprinted Melling HV pump .

Originally, I was going to run a Holley 850 DP which is not a very fuel minded carb for a daily driver, so had been looking for a Vacuum secondary carb around the same CFM, and came across this NOS Holley 1,050 CFM 3 Barrel, this should be interesting.

Hi,

Yea, you have the 3616-1S 3 barrel with down leg boosters and is rated 950 CFM, I have the 4604-S 3 barrel with the smaller tube legs in the rear that allow it to flow more CFM so is rated at 1,050.
If you end up needing a kit, I found this place has them for $60.00, but doesn't include the secondary diaphragm, those are separate and are also $60.00. I have found some gaskets on ebay for these, but there just regular gaskets for other models poorly cut to fit the 3 barrel. But this place supposedly makes them for direct fit.

There is also the Edelbrock Mark 11 4604-S that Edelbrock had Holley make for them with Annular boosters in the rear, but it's rated at 950CFM

I had bought some stuff from Daytona before, but didn't think about them for the 3V, thanks for posting that reminder! I've been happy with their customer service so far! They also have/sell parts for the Shelby "lemans" Carbs that I have such a stupid fascination for...

Update, I had previously sent out my Sidewinder to be match ported, when I got it back, I was very disappointed on how it turned out, so I just shelved it. Eight months later, I pull the manifold down and sent it out to get welded, and then got in touch with Joe D. Craine, who ports and balance flows each manifold runner till their balanced, to make a long story short the manifold showed today, it will make a substantial improvement on my heads now.

These recently showed, Vacuum formed covers, so I mocked them up checking for enough clearance, looks to have plenty of room with the Harland Sharp steel end stands, Aluminum spacers, Cast Iron inner factory stands, Crane Cams 1.76 Ductile Iron Adjustable Rocker Arms with upgraded 7/16" 12 point ARP nuts, replacing the heavier original 5/8' 6 point nuts. Now, I will have to sit down, and shim all the rockers centered on the valves.

Build update: I finally picked up a set of rods, these are a set of custom $2300 BBC Crower Billet rods on sale for $320 out of their Clearance Section.

Because their BBC rods they won't fit my FE crank without modifying it substantially , and so I decided to go a new crank, that being a Scat 4.125" stroker, making my build now 468 ci.

Here are the spec's on the rods:

6.500 CTOC
2.325 BE BORE
.900 BE WIDTH
.927 PE BORE
.900 PE WIDTH
CENTER BEARINGS
GRAM WEIGHTS: 577 / 257

As I mentioned earlier, these are custom rods, for instance their only .900" wide and a BBC rod is .990" wide. The BBC jrl width is 2.008" wide" and the combined rod width are 1.800", leaving .208" side clearance, I am providing and additional .100" side clearance by having .050" machined off each rod where the rods would normally ride against each other. The bearings which have clearance for the crank jrl radius I will flip in the rods, the upper put in the cap and the cap shell place in the upper part of the rod, now the jrl radius is moved to the inside of the rod, allowing for the .050" to be removed from the rods without touching the bearings.

So what I am doing is what is called Piston Guided Rods, the rod side clearance will be set in between the small end of the rods and the pin bosses. I've included a picture of one of my new rods, one of a crank that is set up for piston guided rods, and a picture of a piston, one of a set I just received for mock up purposes, which was hard to find, since it uses .927" SBC pins to fit my rods and are a BBF 4.250" bore. I forgot to mention another custom feature of these new rods they are bushed for SBC .927" pins, and how lucky I was to find these pistons.

The numbers I know are just a general reference, but I think there pretty much in range of what they will be.

The heads are what make the hp numbers possible, they flow around 330cfm @ .600 lift, and the manifold can easily flow that now.

Here's a pic of the Scat 4.125" stroker, which only adds about 40 more hp.
