Which motor

I have a 04 GT that is to nice to mess with much. What I would like to plan is to buy a tired cobra and refresh it. Which motor would be the best to build for HP? The older 5.0,s or the 4.6's and which of those two? The DOHC or the SOHC. This would also help determine the year model also.

You will get the best bang for your buck if you get a 5.0, since they take well to bolt ons and are cheaper to mod.

You can't beat the sound of a bored and stroked 347 running wot but there unreliable. The 302 is a weaker block that can handle upto 450 and not a drop more. The rotating assembly in stock 302's are weak so that will need to be replaced with all forged. I would try and get a 351 and bore it out. It's a Much much stronger platform than the 5.0 and 4.6. There is a guy named scotty on here, he's the one you want to talk to about motors.

That's the old 347 stroker kits that had oiling issues but yes the stock blocks good for anywhere from 450 to 500rwhp but +1 on getting the 351w stroke it to a 408 lol

And where did you get your info on the stock 302 rotating assembly being weak the 87 up to 92 and half was forged then in 92 and half they went to hypereutectic pistons

And the hypereutectic pistons will still take a lot my dads sn95 had h/c/I and a 100shot on the stock hypereutectic pistons

That's some interesting info, but what I want to do is build the motor that comes in the car. Trying to decide on weather to get a pre 96car or 96 and above. Want to keep the numbers matching.

The 4.6 Cobra's only came with a dohc. The 4v's respond way better to modification than the 2V. But compared to a 93-95 cobra, there's a lot of variables with those cars, and years. I was in a similar boat as you a few years ago. I've got a 2V 4.6, and wanted another Stang to play with. I ended up finding a 90' GT for a good price on Craigs list. After a few small mods (and a supercharger) I'm super happy with it. Its true that generally speaking aftermarket parts for 5.0's can be relatively cheap. So its probably gonna come down to your budget in the end, and what you can find a good deal on.

Both are good platforms. The PI 2V takes to bolt ons/mods way better than ppl give it credit for and the old 5.0 is just a proven winner. The 4V will go right into the 11s with the right setup without touching the heads/cams/intake.
