How much hp does my 327 ci have?

Question

i am buying a 1966 chevy impala with a 327 it has a 2 speed trany auto,, im going to put a 4 speed rock crusher in cause i like the whining sound... can any 1 tell me about the marridge will it work?/ how much horse power does the 327 have ectetra?

Answer 1

It will work fine if you have a lot of time and money.

The "rock crusher" is an M-22 Muncie, it does not "whine" unless it has a bad bearing.

To change this over will require installation of a clutch pedal assemble and linkage, a new flywheel and starter, installation of a new clutch and pressure plate, replacement of the transmission crossmember, modification of the driveshaft and installing shifter linkage on the floor.

This is a a very involved changeover, I think I would have the 2 speed powerglide transmission replaced with a turbo 350 3 speed automatic with a shift kit, much cheaper and most everything will fit without modification.

For the exact horsepower of your engine use the VIN number of your car to google the specs and you can find out what version of the 327 you have, providing the engine is the original.

If you like the "whine" install a gear drive timing gear setup, much cheaper than a transmission changeover.

Good Luck!

Answer 2

The base Impala has 137 HP with it... with the 327...it should bring you up to about 359....(Rough Average)

There were many made from 150 hp to 350 hp take the serial # and web search> You will need a doner car to get the parts from> Best to stay with the slush box>Beef it up and lower the rear gear ratio> You can get more hp out of the 327  less $ than the drama of installing a manual trans>
