~ Thanks for posting that link. I see where they added the two more rows to the radiator giving it 4 rows,(like we did). They would have had to open the inlet and outlet as well to accomodate the larger radiator hose size and used the short Corvette water pump to clear the fan. We used an electric thermostat controlled fan out of a Ford Festiva. I see that this car has A/C, on the 4 cyl. models, the evaporator coils were in the engine bay, they would have had to relocate it under the dash like the the V8 Monza version did after '75 resulting in shortening the glove box a bit.
~ The description makes mention of a suspension upgrade to the front suspension, maybe a front sway bar was added but there was no mention of unibody frame strengtheners which would be needed to prevent body twisting with that much horsepower. We should be approaching 300 HP on our 4.3 V6 with our .030 over bore and mild RV cam so we welded in the frame strengthener rails to prevent twisting.
