1955 Chevrolet Bel Air

Owner: Rob M

What we have here is an absolutely beautiful 1955 Chevrolet Belair 2 door post car. Car is owned by Rob M. from Oklahoma. Rob has owned this car for about 4 years. Was unhappy with the performance and reliability in the small block. After some research, he chose to send the '55 to SPS for the LS conversion. We installed a 535 horse power Street Rod LS376/535 with a 4L70E trans. Made 420 H.P.  / 390 torque at the rear wheels on the chassis dyno. For cooling SPS provided a custom core support all aluminum direct bolt in with a double  pass extra large all aluminum radiator, dual 13" fans and extra large condenser (All American Made). SPS upgraded the front suspension to Heidts upper and lower control arms, 2" drop front spindles and front sway bars. To help control the ride SPS, installed AFCO billet aluminum adjustable hydraulic coil over shocks on all 4 corners. Got to stop it, so Wilwood 4 piston calipers were installed again on all 4 corners with 12.8 dia drilled and slotted rotors. All brakes lines were replaced with 3/16 stainless steel. At the end of the brake pedal is an 8" power booster that brings it all together for needed stopping power. All works great!! Got to ride in comfort so what else but Vintage Air with factory installed louvers. Want to know how fast you can go, nothing but the best with Dakota Digital Gauges. For power to the ground try a Moser Ford 9" 3.73 limited slip. Even with the 295 x 40 x 20 rear tires that total 24 inches of rubber to the ground it still will not hook up. All that and this is still a car that can be driven daily if one wanted too. We at SPS are certain that Rob will enjoy the very reliable and dependable ride, not to mention quick, real quick!!!!. Who knows he might even take it to the drags on occasions.
