turbocharge it.
twin t25's or vl t3's something cheap but good, on reversed cast(seires2) manifolds with steam pipe upturns and t3 fladges, run the dumps back into the single system(cheap) use a 2.5" exhuast cheap again
run ford ba straight 6 injectors, walbro intank pump, nice 600x300front mount and enjoy life with 180rwkw odd.
