what's wrong with rolling something for a bit while you build something bitchin in the mean time?
even if you threw a used/Hong Kong phooey intake at it, used carb and a new cheapy swizzle stick at it you'd be, what, 500 and a weekend to go party?
I'd splash that cash easy for a quick grin and scratch that itch while building up Ricky racer motor in the meantime to drop in during the off season.
there isn't a ton of lost investment there-- if planned appropriately and bought judiciously a new intake, carb and headers could all get swapped onto the motor you're building.
not everything has to be Johnny kick *** out of the gate.
