FDA- '84, truck 1/2, 3/4 ton, 145HP, RPO LF-3, 4-Bbl.

If I'm not mistaken, the LF-3 engine was the CA version. The following is from another FORUM:

"The 305 also ran 53cc chamber 601 heads with 1.84/1.50" valves which have a better combustion chamber design than the 416s used on cars and flow more than the 416 car heads."

Chevy engine suffix codes?

Thanks for the information. Do you know if Chevrolet has a website to look up Block #? I had an 800 number at one time that I had called to find out, but that was 20 years ago.

Google "sbc suffix" for dozens of sites that break down the block codes and casting numbers. http://www.mortec.com/ is a good site.

The phone # was prolly 1-800-222-1020. I used it often to get those cool packets of info they would send out to anyone who asked for them, on any model Chevy. I have them for about 4 years of Camaro, an '80 Malibu, '69 Impala SS 427, '64 pick up, etc.

Later on, they started requiring a VIN to show "ownership" before they'd send out the info. I believe they even started charging a fee like Pontiac did, but I've not verified this. Pontiac gave more info than the free Chevy info- had to do w/tracing the ownership, IIRC.

The same phone number is still Chevrolet Customer Service, so they can be asked about the info, and what's required in order to get it.

The info packet they sent out was really a good source of information on RPO codes and availability, a whole section on powertrains for each model, options, specifications (including chassis dimensions like used by a frame alignment shop), wiring diagrams, brochures, "Sales and Hobby" info (pre GMPP), etc. Big stack of docs.
