360 build advice for my '70 dart swinger

schultec14 said
Ok, cool, I would definitely like to change the gears to a lower ratio for sure once im there after a 500 mile trip, and I could pt the 3.23 gears in it that I have laying in the back for the trip down if I had to...Once I'm in town, I'd like to stay with 3.55's for sure. Which specific torque converter would you recommend for this build? Also back to this dual quad, dual plane intake setup...would that give me more power all around, and give me better high rpm flow compared to the single 4 barrel carb setup? I have a friend who has a 327 chevy motor thats on pump gas...that thing has dual quads, not on a high-rise intake, and it is fast! By the way, whats the specs on your 71 swinger JoeDust451? Just wondering..
Thank you,

Its a very mild 360 magnum out of a 95 truck, I love the magnums, our DA is at 3000ft. right now, i'm running an 11" 2800 PTC converter & 3.73 gears, 650dp & summit headers & mufflers, RHS heads, cam is small, .477,.477-.218,.218 @50 112 lsa. I drive too & from the track (100 miles round trip) & clean house on many stangs & LS1 camaros, my 60fts are dead consistant at 1.82 every pass in this heat, best was a 1.79 last month, I run between 12.63 & 12.67 at 104-105 through the exhaust shifting at 51-5200. Best run was a 12.58.

On something like yours, i'd stay with a single carb, a 600 eddy will work good, but i like holleys, i'd either run a 650 square bore vacuum sec. or a 650dp.
