I know you asked moparkid, but, IMHO I think it would be best to go with either the front and rear dutra duals or a modified rear and a front dutra because when it all comes down to things it still is a slant six and again IMHO I think it's best to focus on torque more than HP for a street /6...
i think it depends man.
if you're a numbers kinda guy then go for the 340 and talk him down to probably 7500 or 8000
but if you're not concerned with the whole numbers aspect of everything get the two 318's for 4500
over due bump....
make me a reasonable offer.
willing to trade for either slant six parts or big block parts.
also willing to trade plus cash for big block parts.
it's better than the new Charger, but i still think the new Challenger looks way better.
Also, I'm not too crazy about that obnoxious wing, It remind's me of import guys.
