lets try a tunnel ram
figure without some major changes i've about maxed out the ET on the dart. best its been is 10.30 @ 131. thats with the MP cross ram and the 770 carbs. We tried some 850's on it but the distribution really isn't for crap on that intake. to really get it to be right with the bigger carbs was going to take some distribution dams. So my solution, try the bigger carbs on an intake that shouldn't have any distribution issues. i set it on there last night, looks pretty cool. i'll have to fab up a throttle cable bracket and some fuel lines yet. have to wait a few months before i can see what it really does, if anything.
