My engine was dynoed in a very similar configuration, although it does have a 4.00” stroke crank giving 452 ci, and my cams are 252 @0.050” and 0.582” lift. It has 10.3 to 1 static compression, and was run with a 750dp and 29 degrees total timing to suit 93 octane pump fuel. It made 553hp at 6300rpm. The heads are early iron heads, and pretty close to stock.

I have since changed the intake manifold to a Dove 8V Tunnel Wedge and a pair of 780vs Holleys. I haven’t had it dynoed in this configuration, but it certainly feels a lot stronger to my butt-o-meter. If you read any of the test literature from when these engines were released, they all state the 4V intake manifold suffered from poor distribution between cylinders. The factory 8V intake increased the hp by around 40hp.

The headers have 2” primaries, not sure on length, but the local guy who built them tried to make them as equal in length as he could. The collectors are 4” diameter.

My car has had the shock towers and inner fenders cut away, but has the original front chassis rails. It uses the standard lower front control arms, tubular upper control arms that mount to the original upper mounts. Coil over shocks, and rack and pinion steering. Below is a picture of the engine bay with the 406 out of my Galaxie, I used that to get the car licensed.

Todd, is this the engine that Leon built?

Yes, it is.

VP MS109. Leaded racing fuel is now outlawed down here.

Not wanting anymore 'stuff' in the engine bay than necessary I use a tachometric relay from early EFI systems to control the pump. No tach signal, no pump. Has a start circuit bypass.

Hey Andy, do you have a part number for that relay? I’ve used a similar type relay out of an early 80’s VW before, but I’ve lost the part number. It worked well, would allow the pump to prime for a few seconds when the ignition was first switched on, then would not run unless it had a tach signal.

Tom, I’m in Australia, so emails are probably easiest. I can be contacted on toddkeen65 at gmail dot com. If your friend still want to make a phone call, email me and I will give my number. Thanks.

Nice to see a formal box roof every now and again. Very nice!

Thanks. While I do also like the fastback body style, especially on a race car, I very much like the Thunderbird inspired formal roof.
