327 Chevy small block Dyno test.
Built for my 64 Impala that is being restored. Matching casting numbers, original looks, high torque and good manners were important.
Using the Dyno shop headers, it managed to get 420 torque and 378 horsepower using stock 327 block, heads, intake.
With the stock 2.5 inch cast iron Exhaust manifolds and 2.5 inch head pipes, 424 torque and 362 horsepower. Very little loss was attributed to the low flow rate of the stock intake manifold.
With the stock 2.5 inch cast iron Exhaust manifolds, 2.5 inch head pipes and a 2 inch reducer at the end (the stock Exhaust necks down from 2.5 to 2 inches) 404 torque and 351 horsepower.
With the stock 2.5 inch cast iron Exhaust manifolds, 2.5 inch head pipes and a 2 inch reducer at the end and the stock air cleaner/filter 410 torque and 362 horsepower.
