Hello all,
Well, I did it. I've yanked out my 351 and C6 and I'm stuck. Should I rebuild/replace the 351 or make the move to the big block. Of course, I want the big block. My only real concern is inspection and emissions. I just moved from Arizon to Pennsylvania (AZ doesn't have the "inspection") and I'm not sure how to handle that. Would emissions be a problem too. I have the 1986 351 H.O. (carburated)and will probably stay with carburation. Anyone have any ideas? Any further tips on the conversion would be appreciated as well. Thanks in advance.

Dave
P.S. I have a 4" superlift lift kit going on my Bronco as well. Maybe even a body lift. Hey, if you're going to run a big block you might as well have some large tires to turn. HE HE!

 

I think you need to find an 86 or later 460 to meet pennsylvania requirements.

 

I think so, also, and I also believe that you'll need all the factory smog equipment intact and swapped over, also, to keep the inspectors happy. Is there still a provision that will only allow a swap if the engine in question was available as an option in your particular vehicle? If someone wants to push the issue, they may try to make the case that Ford didn't offer a 460 option for the '86 Bronco (I'm sure someone will correct me if I'm wrong on this!) and, therefore, say that you can't legally swap one in. The only reason I bring this up is that a friend of mine had a factory 460 in an '86 F350. As I recall, he had next to no emissions (compared to the lighter duty V8 trucks)on it from Ford, including no catalytic converter. If you were to swap one from an '86 into your 1/2 ton truck, with no cat and the scant few emissions that they put on that engine in '86, I can see an inspector giving you a hard time if he or she wanted to.

 

That is consistant with my information. The Bronco never came with a 460. So if the inspector is splitting hairs you would fail. But also the 460 was in one ton and heavier trucks that were allowed more emissions than normal cars and light trucks. So even with all the smog equiptment working perfectly, you may pass the smog tests for a F350/E350 but fail for a Bronco.

You had best do some careful checking here before you spend real money.

Thank you all for your replies.
You're probably right. But I just can't help myself. What do you all think about the "SPECIALLY CONSTRUCTED VEHICLES, RECONSTRUCTED VEHICLES AND STREET RODS" code. Do you think I could squeeze myself into that catagory. I.E. a retitling of my Bronco under the "special vehicle" code. After reading the code,(http://www.dot.state.pa.us/)It's chapter 19 "SPECIALLY CONSTRUCTED VEHICLES, RECONSTRUCTED VEHICLES AND STREET RODS" I think I could technically qualify. I know, I know, I'm graspin at staws. But damn, how cool would a 460, (with after market fuel injection...Holley projection) be in my Bronco. As usual, please let me know what you think.

Thanks
Dave

 

I live outside of San Antonio in Texas. Whenever i get my '83 bronco inspected i just go to southside of town. They'll pass you for the right amount of money. If you have any big cities around maybe consider that an option.

 

From posts I read on other boards, smog ***** in east coast population centers use legislation based on California's code. There aren't many people in that state who can get a bootleg pass as the fines are high enough, first offense, to put a garage out of business.

I don't know the vehicle laws in your new state, but compared to AZ, you're in the middle of some serious control over what you can drive on federal funded roads. Federal tax money for highways requires adoption of federal emission standards and counties with very high populations receive the lion's share of that money.
