this is my first post, and i used the search to no avail

so i have an 03 stang gt with a blown motor, and i decide that it was high time to do something different than the average joe with a 4.6 ( i live in the south, and you could dump every 96-04 gt into the Tennessee river and walk across).
and there's also an abundance of 50hs goin around too.

So i figured hey, why not pay homage to the stang of old and drop a 351 in?

I've been doin my homework on everything needed for the swap, and honestly i think it would cost more money for a set of heads than it would for the actual swap, and the extra 100lbs doesn't really bother me. so dont try to talk me out of it lol, i want this to be unique

anyway to the point. I plan on building up the motor but i wanted to do something mild first, like around the 300-350 rwhp range EFI. how hard would it be to achieve that for these motors?

 

with a 351 it wouldnt be that hard at all. honestly if you cant make 300rwhp you need to be kicked in the nuts

 

300-350 RWHP can be done with basically a stock bottom end and just minor improvements to heads, intake, carb etc...
