Thread: Question about 500 and a 454 big block

Tweet

On the 1976 Cadillac 500 . The factory HP rating was 190HP and 360 lbs torque . On the info I have . By taking a 1976 500 and removing 0.020 from the cylinder head deck from the stock 120cc chamber Heads . This will bump the C/R from 8.5 to 8.7.1 . Also do a std valve job with new springs 105 pound seat pressure with HD retainers . With every thing else stock inside the engine . Then with a tune up ( good set of wires and cap-plugs ) install a 750 Edelbrock #1407 with an adapter plate on the stock manifold . With only these mods you will have 303HP at 3900 and 468 lbs torque at 3300 . This is near base level HP building . I have more info if you want more HP . Also an Edelbrock performer intake #2115 will add up to 25 more HP . And cut some Lbs frome that 600 Lbs engine .
