i am thinking of possibly swaping my 302 for a 351... good idea or bad idea? how hard is it and how much would it cost me? Worth it?

[Racinjason81]

its a good idea. you will need a 351 oil pan,28oz FW,351 lower intake,351 balancer,351 headers,and351 dist.

sweet i think i can get a good deal on the motor? is it really worth it though is it that much better or easier to make more power out of a 351?

[Racinjason81]

They have more power and torque potential than a 302,cuz theres no replacement for displacement.Are you gonna keep it Injected?

yes i would keep it fuel injected

[95wip]

what would be my best bet cost-wise to build up to around 400-500hp or high 11 low 12 car and posibly run nitrous to get it there?

remember it is a 95 not a fox

351 is a GREAT IDEA! trust me. but get a 408 stroker kit. With all the right matching parts I would think you could make it run in the elevens all motor. I might be mistaken but I don't see why not. There are 408's making over 500HP.

and you can always run nitrous after the fact if you aren't satisfied with the performance, but i guarantee you, a 408 will be PLENTY of power for you.

I have a 351 and it is SWEET! When I get back to the states im putting a 150 shot on it. My brother in law is supposed to take it to the track for me to see when it runs 1/4 mile on the engine. I could let you know when he does. I am thinking mid 12's, so that is why i think you wouldn't have any problem getting in the 11's with a 408.


how much money do you have to spend?

[95wip]

what are we talking for money on this cause i am seriously considering it and yea let me know what it runs! 408 stroker would make my buddys shit themselves when i burry there cars ahaha

[94' Cobra 351]

to be honest, it is not going to be cheap to do this. All the nice goodies like heads and what not add up fast. I didn't build my engine, I just bought it the way it was. But I would think it is going to cost you at least 8,000. You could make the same power by putting a turbo on your 302, but the engine isn't going to last as long. Are you planning on doing the work yourself?

what i like about my 351: to the untrained eye (99% of people out there) it is very difficult to tell the difference between the 351 and 302. So you could have a 351 stroked to a 408 (almost 6.7 liters if i'm not mistaken) and when you pop your hood your friends will just think you have a 5.0 with a few mods. That is until you start it and it rumbles the concrete.

i like the 351 because it is solid and also even stock cubes is more than the most i could get out of a 302...plus i want the car to last a long time.

Are hypereutectic pistons going to be ok for 100 or maybe a 150 shot of nitrous?

I have been wondering the same thing. I am going to go with a 150 wet shot on my 351. Are you thinking about doing this on your 302?

I have heard of people running a 200 shot on a stock 302, but I wouldn't suggest it.

You shouldn't have problems with the 150 shot, but just make sure you have everything to support it. IE, fuel pump, injectors if its a dry shot, tune, proper set up and safety devices (window switch, wot activation)

[95wip]

no i am not going to run it on my 302 i was pricing things out for a 351 and see what kind of rotating assembly but i found one from scat with steel rod and crank and froged pistons would that handle a 150 shot and posibly a 200 shot?


94 Cobra 351: what do you have done to your 351 and what kinda power is it making? gas millage(not concerned, just curious)? and how does it run just normal driving conditions?

Why wouldn't you just go with a 408 set up instead?

But yes it should handle a 200 shot no problem if it is done correctly.

There should be a list of all the mods on my vehicle profile. I haven't had it on a dyno yet, but i would estimate around 400 hp. I only get about 12 mi/gallon in the city but that is mainly because of the cam in it. The normal driving conditions are fine beside the reduced gas mileage. I recently drove it from New Jersey to Chicago in a straight shot and had no problems.

The rotating assembly i found was a 408 set up ? does that always mean that it is stroked?

Yes, that means it is stroked. Stroked simply means you are increasing the stroke (hence the name) of the piston inside the cylinder. A really basic way of thinking about it: say that when the piston is at bottom dead center it is only 75% of the way down, then it returns to top dead center and is all the way up. Well utilizing a different crank, rods, and pistons, you can make the piston travel past 75%, essentially making the cylinder "longer" Which allows more volume inside the cylinder which equals more fuel and oxygen ultimately creating more power. That is a pretty crapy explanation but hopefully you catch my drift.

actually i understood perfectly thanks i never was sure what it meant!
