318/340 questions please help!!

I have a 71 duster that came with a 318 and a 727 it has 8 3/4 sure grip it what I was told. Basicly Im looking sleeper/nice streeter, something that isnt over the top just nice power. So I thought 350-400 hp was good but I dont know, your thought would help lol
Thanks guys

Check it, make sure it is a 727.


if the stroker is a route you might want to take, it's the easiest way to get streetable 400HP's......

If not, we will need to further investigate what exactly you want to spend, your abilities, etc.

And watch out for rumble, he was kissing MY *** earlier...... I think he may be ill!

hahahahahaaaa
