OK ? of the day.

Can anyone tell me where I can find the law (number of bill and stuff if possible) on the MO books that states what the limitations on motor swaps in regards to original engine size vs replacement engine size. The one thing I found at the DMV site was that it had to be like make or manufactor. That is at best vague so figured there was something somewhere that would clear it up. I am really wanting to plan a 289 or 302 swap for my ranger that is currently running a 4.0L v6.

Thanks!

Does that say that I can't put a bigger motor in than is available in that model year and any year since then? OK my head hurts!

blah blah blah blah

 

Alright, I found the info and now you want me to TRANSLATE all that crap too?? ROFLMAO!!

I think you're best bet is to ask someone at an inspection station since they are the ones that will make the final call. If you don't know anyone, my mechanic buddy here will tell me. He just passed his inspection renewal so I know he's up to date on the regs. I can ask him Tuesday if you want me to.

 

I think I see a burgeoning opportunity for a business in (ahem) REPLACEMENT ENGINE ID TAGS....
Need jeff's forge too...

 

Ive got a family member with a 383 Chevy in a Ford truck.

As far as I know, you just have to be able to pass the emissions standards for the vehicle that is described on your VIN

A good majority of the employees at the emission stations wouldnt be able to tell a cummins diesel from a chainsaw motor.

 

I tried to do every thing legal on my swap after spending 2days on the phone with socalled head of veris departments of motor vehicles and DOT.I have had a diesel in my old ford since 93 a 372 Perkins and a 6.0 Perkins that it is in it now.each person didn,t know what to tell me ecept for one women she read me the riot act told me that I had to take that motor out now.And said that if I got pulled over the H.P. will make me take it out on the side of the road .I just told her OK. I have been around alot of H.P. they just lookat it and smile I just tell them I went from 6mpg to 25mpg.It is still regesterd as a gas.

mainly it up to the inspector...down here for a while they were heck on a s-10 w/350 and rangers w/5.0 but now it's cool and a hp usally don't ask what motor you got in there and won't ask about it or check it unless its...

loud / doing burnouts donuts racing ect.

your doing 120 in a 40 zone

or running drugs

 

I had no idea there were rules about that ! oops ..

 

Hmmmm, I wonder how they'd feel about a souped up 6.0L Diesel in a Ranger? Hey vloney, I still got me that spare 6.0L, you got a scrap Ranger anywhere?

 

I think J&B aid HE did....

 

So let me make sure I have this right. As long as I am not bellowing smoke, from either the exhaust or the tires, producing decibels above and beyond the normal engine sound from either the pipes or the marble grinding under the hood, running pink slips, shine, meth, pills, illegals or guns and my inspector doesn't pop the hood I should be fine in making this swap? Just in case the inspectors in my area turn out to be turds about this (North Central MO has some real nasty State inspectors, think they were either hugged to much as a child or not enough but they have issues) where would you boys recommend area wise that a fella might have a little less headache with a MVI?

Thanks for all the post, they have been……enlightening!

I don’t care how hot she is, she could drive a chevy!

 

basically yes just find a good inspector... what alot of people here do is... if they live in stl the have family where I live at they register the vehicle down here (no smog check) and get it re inspected here..

 

It can be done if ya know the right people . oh man gotta go the smog police just kicked in on me..
