Engine info needed for UK legislation
Hi fellas. I'm not a truck owner but I do have a truck engine in my 56 Nomad over here in England and I'd really like your help. The UK government are introducing legislation whereby I'll need to prove the power of my engine, It's a 350 with a 4 barrel and from the engine number K1109TDD and block casting number I've found out that it is a truck engine made either in Canada or Kansas (which?) on Nov 9th 1972. When searching the suffix code TDD all lists I've seen simply state '350' with no other info. A list in Classic Chevy World back in 2001 claimed TDD was a 1972 truck 350 with a manual transmission but where that info came from I don't know,
I found a picture on this forum of what looks like a page out of a brochure or manual. I'll try and find it again and post it up. It's dated January 28 1972 and page number 22 in the Engine & Clutch section. It's titled HIGH TORQUE 350 V8 and lists the engine's: Applications (GE20-30, PE30, etc), Basic Specs (engine type, piston displacement, etc) and Test Procedures (to obtain the power/torque curves shown below it. And from that it claims the engine shown is 175 hp SAE Net and 290 lb-ft SAE Net. Was this the only 350 4-barrel truck engine available in 1972? And whether it was or wasn't I'd like to find out the title of the manual that the page is out of. 175hp has been mentioned in other posts but where does that info come from and how can I tie it to my TDD engine? Can anyone help me in determining the specs of my engine but especially finding verifiable sources of info (brochures, shop manuals, etc.) can use as evidence if needed. Thanks for reading this and hope to 'speak' with you soon. Ian |

The page from the manual I mentioned above is in this thread:

Re: Engine info needed for UK legislation
That publication was called "Truck Data Book". The title page says "CHEVROLET.........TRUCKS" followed by the year.
GM used to send these out to anyone requesting, but I heard that this is no longer the case. I got mine for 1969 and I'm sure there are loads guys here with the 1972 version. Maybe someone can send you a copy of the page you need. -BA |

All those 70's 350's were 185 hp. The 'Vettes were a little more.

Re: Engine info needed for UK legislation
It seems TDD is either a 72 or 80 motor. You'll need to dig deeper to find out which year.
This link shows your code. http://www.nastyz28.com/gm-chevy-cod...s-suffix-7.php Lmc truck shows your code so it indeed is a truck motor. http://www.lmctruck.com/icatalog/cb/full.aspx?Page=10 You'll need to check the date code on the block. Look here for a few pics of where to look. http://www.mortec.com/location.htm |

WiL, Maybe I can find a pdf or something on the internet. Are there some words between CHEVROLET and TRUCKS or is this like a look-up reference as in 'Truck Data Book', Section 'Chevrolet', sub-section 'Trucks', sub-sub-section '1972'? Geezer, That lmctruck link is handy. And, btw, the engine is definitely 1972. To anyone, Does anyone have a copy of the 1972 truck info to be found in the Truck Data Book? |

retard the timing, put it on a dyno and show the print out.

Nomad, is this for taxing purposes? If so, I wonder who thinks up these laws?
I guess they figure the higher the horsepower the more energy is consumed but it's not always the case. Some of these modern engines can be super efficient and have more horsepower per cubic inch or cc displacement than older larger motors. |

The literature from the GM Heritage site has HP/Torque ratings if that's what you need.
