Carousel Red 1972 LeMans convertible, engine view. It's a 455 HO Ram Air engine. Pierre explains, "I wanted a little more Poncho power but didn't want to hurt the original #'s matching 400ci motor which is in perfect running condition. So I started looking for a used 455 to rebuild. I found a complete YE code 1971 455HO motor with the correct round port heads, 4 bolt mains block, nodular crank etc. This was too good to pass up! The engine was sent to Brossard Performance into the skillfull hands of Claude Robitaille where it was treated to a full blueprint job, bored .040, align bored and decked. We used new speed pro forged 9.5 to 1 pistons, total seal rings and eagle H-beam rods for insurance. The bottom end is closed with a Milodon pump, windage tray and low profile 8 litre pan. The heads were prepped by Alain Tremblay of Airflo-Tech, he performed what he refers to as a mild stage 2 street porting & 3 angle valve job with Manley stainless valves in bronze guides. They now flow a modest 248 cfm on the intake and 211 cfm on the exhaust. A complete Comp Cams Extreme Energy 274h cam kit, Cloyes double roller timing set and a set of 1.63 ratio Harland Sharp roller rockers completes the valvetrain. Everything fits nicely under stock Pontiac style chrome valve covers. The engine is fed by a Barry Grant Street Demon 750 cfm carb mounted on an Edelbrock Torker II aluminum intake which is the same height as the stock intake permiting the use of an Ames reproduction Ram Air filter housing and hood pan kit. Ignition duties are handled by a re-curved GM HEI unit, Accel coil and Moroso wires. New alternator, power steering pump, water pump, 4 core radiator and starter were installed. A set of Hedman ceramic coated headers and 3" exhaust system with crossover X pipe and Flowmaster Delta Flow mufflers exiting through 2-1/2" mandrel bent tail pipes and original 1972 style chrome exhaust splitters let the torque beast breathe freely. The sound of the engine is awesome. The engine was painted Pontiac silver blue of course. It was dynoed at a modest 465 hp at 5000 rpm & 525 ft-lbs of torque at 4000 rpm on pump gas. The perfect street set-up. The stock no's matching 400 engine is stored. Transmission duties are handled by a TH400 which has been treated to a complete overhaul including a B&M shift kit and an 11" TCI breakaway torque converter and GM deep pan. The stock no's matching transmission is also stored. The rear end is a reliable 12 bolt with 3.08 gears upgraded with a Powertrax no slip posi unit. Brakes, bearing and seals are all new. The car rides and handles great, the performance is breathtaking yet very civilized, it will idle at 950 rpm and hold 180 degrees in hot weather traffic."CLICK->
Carousel Red 1972 LeMans convertible, interior view. Pierre continues, "The interior was redone with a complete new P.U.I. interior from Ames Performance. Seats were disassembled, frames sandblasted and painted, new springs installed along with new seat foams before installing the original style Morrokide seat covers. New seat backs, bases and all new chrome hardware, new door panels, door panel seals, carpet, floor sound deadener, firewall and under dash pads etc. The dash was sent to (Just Dashes) to be recovered in new vinyl and re-install the correct 1972 only Pontiac dash emblem. All dash instruments were disassembled, cleaned and painted before re-installing them. The original console and shifter were cleaned, lubricated and reinstalled. The heater box was blasted, painted and resealed with all new seals and gaskets. A new heater core and fan motor were used. The power top was treated to a new pump, two new cylinders, steel braided hydraulic lines and a new dash switch. The whole top mechanism was disassembled, sandblasted and re painted gloss black, reassembled with new bronze bushings. A new reproduction front top bow was also used. Once reassembled and functional the car was sent to the upholsterer to install a new canvas top with a glass back window. New weatherstripping was installed everywhere. The original Formula steering wheel had some cracks on its rim and just didn't look right in the new interior so it was stored and replaced with a Grant Collectors Edition leather wheel."CLICK->
