Hey guys,

Sooooo, a 351w in a sn95. Yes or no on CA smog? I think it is a stretch but might be a go.

What do you guys think? Pointless attempt?

What year? If it's a 94 or 95, they had the 302 in it, so it might be more feasible.

no, not legal. they dont consider the 95 Cobra R a valid platform to base the swap on.

besides the Cobra R, the 351W was only offered in a truck platform, and cannot be transplanted legally into a car platform.

NC ftw.

but couldn't he just tell them its a 302 if its a 94/95, or stroke a 302 out if they are hardcore and actually know how to tell the diff between the 2.

I thought you just had to have the smog stuff from the car the motor was sourced from?

I suppose you could disguise it as a 302 and hope the smog guy isn't up on the external differences between a 302 and a 351

back in the 80's I had a '66 with a 351 Cleveland and I convinced a smog tech that it was a 289... I just put on blue valve covers and a big blue air cleaner with a 289 sticker on 'em ...of course the checks were a lot simpler then and 66's didn't have much in the way of required smog stuff other than a PCV valve...but still

You can swap a motor that came in a newer model of your car into your older car. You still have to have all the smog equipment from that engine intact, and they base the test results off the smog specs from the motor you swaped in. If you tell them you have swaped the motor from a 95 cobra R into your car it should be legal as long as your car is a 95 or newer. You will have to use the correct cobra intake and every performance part will have to have a carb number that specifys use on a 95 cobra R, which I dont think there are very many. Most of the stuff you would use on a 5.0 wouldnt be legal on a 351. Also I wouldnt even bother taking that to a smog shop, I would go straight to a referee so you dont end up wasting any money at a shop. I wouldnt do it if I were you, I would build a 331 and call it good cause no smog tech is going to be able to tell you did it.
