mac cai
FMS maf
edelbrock TB
professional products u/l intake
F303 cam
edelbrock performer heads
.030" over, 8.5 CR forged
mac shorty headers
mac o/r H-pipe
flowmaster 40s
no roof, no side windows, nothing from the front seatbacks aft - no plastic, trim, insulation, just sheetmetal


Some of those things are legal, such as the throttle body, possibly headers, heads, etc. The cam isn't though. But it went through state patrol inspection because it was an out of state rebuilt title and they looked at the receipts for it all. Hell, I drove it 12 hours in one day to get to the inspection and home with no license plates on it whatsoever, trip permit in the glove box. I got followed by a cop for a few minutes, but never pulled over.

Ok I've been reading that website and here's my interpretation:

Putting that chubby in is considered tampering with the emissions controls, and is therefore illegal at the federal level.

and on the subject of engine families:

So you can use any engine that has been used in the mustang from 93 to current.

Same for 4-popper to v8 swap. Grab a 302 complete with wiring harness, stock computer, fuel injection, and emissions stuff and throw it in. It'll actually be legal. It's your only option to remain completely legal.

You could also take that 302 and toss a 347 stroker kit in it, get a Tweecer or some similar tuning device and program some maps - emissions testing map and a power map. Chuck a G-force t5 behind it and you're good on power and you won't break your tranny. Yeah, it's not cheap, but it's got a chance of being legal.

I have been to this website. Problem is that the state stopped using the clean air force statewide program in 01. They calmed down on this stuff alot because it was getting out of hand. I know for a fact that if I was to put a sbc in my mustang it will be exempt. Im going to talk to a guy around here that has a sbc in his mustang and he runs 9 70's all day long and will drive the car to and from the track. He is an old timer and reaaaaally knows what he is talkin about. I think Ive decided to go with a manual valve body in a TH350/400 trans. If the emmisions get too much of a pain in the *** there may be a fox body on here for sale ill just get another motorcyle. This is gonna drive me F***in nuts. Ha i think im just gonna bribe the emmisions man. I gotta stop lookin at 460 mustangs low tens on stock shortblocks is an unfair advantage!!

Can you provide a legit source that proves it? I just find it impossible to believe that they'd make your vehicle exempt from all emissions requirements if you put a different manufacturer's engine in it.


Ok, as of 12/31/98 there is no longer a special exemption for "hot rods" which your engine swap would fall under. If the swap had been done before that it would be grandfathered in.

alright, alright,. No more chevy! Is everyone happy. The new idea is..... run a stroked 351 build it with reasonable compression, when it comes time for emissions put a later model h pipe (yea the ones with 6 converters) and put on the 2 barrel carb and turn it lean. This should work (theoretically) it may not run well for the 1 day out of a year but as long as I pass ill be fine. I wanna be somewhere 400+ with the normal tune (4 barrel and no cats) Then go with about a 200 shot. And if it doesnt work Ill sell the car and buy a 5.0 sn95 and make it a fun good looking car not a fire breathing monster. give me some feedback on my new idea Im curious as far as heads go. I'm pretty knowledgeable when it comes to porting what would be my best options as far as stock or cheap aftermarket.

The idea of having to fab all that stuff was making me loose sleep.

Not sure a 351 will be any more legal than a 460 would be. I've heard that 460s drop right in without too much trouble.

stop it horatio, you're going to start frustrating him.

lol

yeah, but a 460 worked over has way more potential. No need for a new crank or possible grinding on the block to get clearance or anything. 400hp is easy.

Like I said earlier (or maybe I didnt) I toyed with the idea of a 460. If I wanted to build the "Ultimate" street car I would probably build a 10:1 pump gas aluminum headed 514. Put an ungodly amount of nitrous on it and spray to the tune of like 800. But the notchback mustang is nose heavy enough. If you guys follow the american iron scca series you know the griggs 40 car. That car is so front end heavy they moved the seat back and put an extended steering column in it just to get closer to 50/50. Ive also talked to guys runnin stock headed 460's and the consensus is that if your not goin 10's with decent traction you're doing somethin wrong. But I am easy to please and I can make as much power as I want out of a 351. I'm a suspension buff so I want lightweight moderate power with no tire spin (If there is such a thing) The extra weight of the BB would be against my taste IMO.
