Hi everyone, again help is much grateful. I have a 1974 dodge dart sport with a rebuilt 318. The engine has a 600 eddy carb with the #2176 eddy performance manifold. The heads are stock( for now), but the plan is to get the 318 heads reworked, or a set of 360 heads reworked, or try and find a set of 302s with 188 valves. I have a comp cam 477,480 with the 904 tranny. Being that iam a newbie and this is my first mopar build, must also mention that the pistons are stock, but it is at zero deck. I have been scanning this site about which gears to use in my car. I dont really care about the gas mileage or highway driving, just a nice romping 318 street car, with good jam out of the hole. The car now ha s the 7 and one quarter 256 gear rear end, but was planning on changing to the 8 AND 3 Quarter sure grip, with a 3000 stall. Which gears will be the best for me? I was thinking with that stall maybe 410s or 430s or 456s. Please let me know what you think, dont want to get the wrong choice and have it be a dog. Is the stall okay? .Thanks guys , like i said before iam a newbe and need help to be steered in the right direction. Newatthis
