Sorry I do not have a complete list of cylinder head casting numbers that are used on this engine. All of the proper testing and machine work have been performed to the heads on this engine to ensure trouble free operation.

This is a complete engine. You will need some simple bolt-ons, some of which could be reused from your original engine. Those items would be such as a carburetor, spark plugs, spark plug wires, water pump, pulleys, etc.

This engine is not intended for use with turbo chargers or blowers. Use at your own risk since that will void the warranty.

The flex plate is different but this engine does come with a 153 tooth flex plate. If you need a 168 tooth flex plate it is part number 91048364. Other than that everything else from your 1981 engine will bolt up to this 1 piece rear main engine.

Sorry all of the BluePrint Engines that we carry are passenger side dipstick. I do offer a GM crate engine that has both drivers and passenger side dipstick provisions on the same engine so that it fits more applications. The part number for that engine is 35519244450.

Cam question? This cam has spec's close to the Comp Cam Thumper. Does it have a rough thumping Idle?

Cam question? This cam has spec's close to the Comp Cam Thumper. Does it have a rough thumping Idle?

Answers

EricM
No this has a fairly smooth idle but not quite as smooth as a stock engine. The Comp Thumper cam has a little more duration and quite a bit different Lobe Separation Angle and will have a much rougher idle than this engine does.

Answers

With the 9.5:1 compression ratio it would be preferred to have 89 octane or higher but with a properly tuned carburetor and conservative timing you could probably get by with 87 octane.
