Everything greater than 1 ton pickup is considered med/heavy duty and thus cannot be used as a donor into a car.

Two questions
1) :confused: How would they know if a 350 is from a truck or from a car? (two different families)

2) Can I throw a 454 from my 90 dually into my 90 S-10 as long as I keep the driveline and components intact?

Tim the legislature doesn't want us to implant newer engines in our classics because they want all classics removed from the roads. I still haven't figured out what they have against old classic vehicles. It must make our state look backward or something like that, or its like the confederate flag (it reminds them of the bad old days). :confused:

1). I don't know of any 3 ton trucks with a 350ci only. Plus, the Refs are smart guys....they know a great deal about engines and components. I don't think heavy duty vehicles have the same emissions components as smaller trucks.

2) If your Dually is rated 1Ton or less, then yes. As long as Engine, Trans and ALL emissions equipment (incl. fuel tank etc) is transplanted, then yes.

I thought that car and light duty trucks were considered two different families? I wonder if they (the refs) have books of engine serial and casting numbers.

Do it, the worst that can happen, is they laugh at you.
If they turn it down automaticly, then forward it to some one with some weight....Leno... SEMA...tripple a...

That is what I always thought too, but apparently, trucks 1 ton and under are considered light duty, thus in the same family as cars.

I even questioned him twice about it as he kept using the example of a TPI Camaro engine in a Chevy pickup truck.

The only reason that the two Illinois counties close to St. Louis have to have testing is because the St. Louis Metro area failed Federal EPA standards and testing was then mandated for all areas around it. Rural Illinois is not subject to testing. Politics does make a difference. Legislation is pending in the State of Missouri to withdraw funding from the emissions program which could be an end to it. If St Louis no longer conducts testing I doubt that Illinois will continue it, and then I won't have to deal with it.
