Stock 360 from a 1984 Dodge Pickup
Just..Make sure you have a oil pan that will fit...I dont know if truck 360 oil pans are different than cars..and get a nuetral balance flex plate, because a 360 is external balance and a 318 is internal.
It will run pretty good....given your carb is good, and close to spot on, and you can tune it.
.410" lift cam, 4.0" bore, 8.5:1 CR.....with 4 bbl carb, and free flowing dual exhaust, it will make approx. 320hp, and 350tq.....which will feel pretty nice for what this swap, costs to do.
Probably run a nice 14 sec. quarter.
