Kevin,
My gallery has photos like this:
which is the Torker II with the Holley 1000cfm throttle body.
I use a K&N oval air cleaner with about a 4" tall element, not sure this is exactly it - been too long - but same idea:

And here's the scoop:
The engine is a 521 with a Crane Hyd roller, Ford Racing aluminum heads around 10:1 compression and Holley EFI. If you want some more specific info, just ask.
This is an E-M Cobra dimensionally, so it may not match exactly with any other brand of replica...
