is my truck federal? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

menace121978 · 07-16-2009, 01:41 PM

how do i find out if my truck is a federal truck? does the vin# tell me?

i was looking over my last smog and it said FED. on it. went back to the smog guy today and he said they type it in. i asked him how do they tell and he got all tight lipped on me.

please help!! i'm deciding on the drivetrain and want to start ordering... thank you, Dennis

Do you have the engine RPO (either from the SPID label in the glovebox or is there an emissions tuneup label on the radiator support)?

menace121978 · 07-16-2009, 03:43 PM

the glove box says ls 9 (350 4 bbl).

if both were lets say "missing" how else could they tell?

menace121978 · 07-16-2009, 05:37 PM

keith where'd ya go??

What is a federal truck?

menace121978 · 07-16-2009, 08:35 PM

a federal truck can be smogged under less strict laws. the cutoff is i believe 1978 and all a fed. truck needs "i think" is smog pump and air injection tubes on the headers. and maybe cats.

I went home...

Is there an emissions code on the SPID label? It would be an NA, NB or NC code (like NA1 or NB2 or something).

Cats would be required, as they were installed starting in 1975.

Engine RPOs are coded in the VIN. I'm thinking the reason he got all tight lipped is because he didn't really know what equipment would be required (he just read that the computer told him it was Federal emissions).

"Missing"

Could you get by with a hollowed out cat, or are they pretty strict on what the emission level should be?

On another note. Couldn't all of our trucks be considered "Federal" since the Government now owns part of GM?

menace121978 · 07-17-2009, 10:08 AM

yea most places are pretty strict around here. they usually use an infra red temp gun to see if the cats working. but you have to realize i dont mind the cat... its the damn vacuum hoses, heat riser, egr, tvs, canisters w/ 6 different hoses going in and i could go on and on... im sure the '76 i had didnt have cats and it was a fed truck. has been a while though...

laugh it up now....because you'll be putting it back on soon enough, with all the laws changing.....

glock35ipsc · 07-17-2009, 11:27 AM

I've never had to have an emissions test in all of my 39 years.

JohnC · 07-17-2009, 11:35 AM

Sure hope not, and bite your tongue for saying such a thing!

I will bite my tongue! I like not worrying yet either, but think it's inevitable....(sorry for the hijack)

Our '75 swb 1/2 ton 350 had a cat on it.

I remember specifically because it blew up and scattered it's guts all along the exit ramp...

Thanks, Glock -

asphaltburner · 07-17-2009, 12:18 PM

Wow! How bizzare! My '78 3/4 ton 4x4 FRANKENTRUCK did NOT have a cat on the ol' factory exhaust, nor is it marked "Cat" anywhere, as is my '76 Camaro. Sure doesn't seem like a P.O. could have removed it,...exhaust looked pretty untouched and there's no heat shield either. It WAS sold in WY.

menace121978 · 07-17-2009, 02:10 PM

glock thank you and keith too! thats not good news though.

im still wondering how the smog place would know??

glock35ipsc · 07-17-2009, 02:18 PM

Make a new SPID, and go to Brothers and get a FED engine emissions decal

menace121978 · 07-17-2009, 03:36 PM

great idea!! thanks glock!!

glock35ipsc · 07-17-2009, 03:38 PM

Or as for the SPID, you "replaced the glove box liner with a new one and couldn't transfer the label".......

menace121978 · 07-17-2009, 04:05 PM

gotcha!

1 last question, what EXACTLY is needed for a federal emissions 1978 1/2 ton?
