easy way to convert your challenge car's plain old carbed small block to EFI:
LT1 intake that has been machined to bolt onto gen1 small block heads. the old holes were filled and new ones were drilled. coolant fittings added to the rear. distributor hole machined, EGR blocked off. the intake has also been ported
includes throttle body, fuel rails, injectors, remote thermostat housing with thermostat and water neck, small cap HEI distributor with coil, cap, and rotor, i'll even find some GM sensors for you. build a megasquirt and a wiring harness and be off to the races. $325 shipped in USA - GRM only price. people mod the intakes and sell for 425-450 for intake and thermostat housing only on the vette and camaro sites as conversions for TPI cars.
i bought it to convert my TPI C4 but stumbled upon a killer deal on the ever-so-freaking-cool lingenfelter superram intake manifold.
