Motor and FI Description
It uses a firewall mounted computer (TEC II) with coils from electromotive
(www.electromotive-inc.com). The ignition is crank triggered (toothed
wheel mounted behind the pulley). The distributor is a milled off factory
distributor used to drive the oil pump. The electromotive system allows
complete control over the fuel injection and ignition timing (thus can be
complicated). You can even control electric fans, shift light, or Nitrous.
It has dual rev limiters. You can download the manuals from the web
site (under the TEC II area).
The throttle bodies have two injector ports per cylinder.I am currently using the inside port for fuel (pointing down the port as
described before). The outside injector ports are used to supply metered
idle air to each cylinder. There is a small box in the center of the
intake manifold (below fuel rails). This box serves two purposes.
It has passages that collect the vacuum lines from each two barrel and "sum"
them in a larger plenum which is connected to the MAP sensor. Thus
the map sensor sees the average signal from all of the sensors. The
box also has a separate idle air circuit which connects a standard idle air
motor with large ports that route air to each of the two outside rails in
the picture (not the fuel rails). In each rail I have orifices that
meter the air in each cylinder.
Aircraft (Earls) -8 lines supply fuel from the tank two a y block which sends
fuel down each rail in parallel through -6 lines. The two fuel systems
are joined again and routed through a pressure regulator back to the tank.
It uses a Bosch 80 gal/hour pump.
The motor is a center oiler '67 marine block. It is at 4.25 bore with
a 428 crank (3.98"). Dove MR heads, FPP push rods, roller rockers,
stands, etc. Comp cams 294S. Ross pistons with 10.4:1 CR.
Le Mans Rods. ATI damper and March pulleys. One wire 100 amp
alternator and Tilton super starter. The total motor complete as you
see in the picture weighs 503 lb. Not bad for 452 CI (7.5 L) and
approximately
540 HP.
