need help on build 440

i just recently bought a 71 swinger with an 8 3/4 posi and 727 trans.... but i have plans for build a 440 for it.

well i was wondering how i can build a 440 engine for a "cheaper" price thats making some decent power. i am using this car for a street/drag situation so i dont want it to rank, but i want it to have more jam then it came stock

im new to muscle cars in a way since im only 16, but i love cars. so since im still in highschool my budget isent too great but still is kinda open.

i have some questions first that have been realllllly bothering me

1) i found a 440 out of an 71 new yorker, can I use this engine or is useless? i dont know if these would be different engine compared to the high performace block.

2)i have heard that heads off of a 67 have a closed chamber...and if the magnums have a bigger exhaust. should try my hardest to find these heads or can i port an polish the heads? which is better?

3)should i get the egine balanced?

4)i have some connceting rods that came out of an 426 or 440 6pack..should i use them or are they to heavy?

thanks you guys, i really do love this forum

p.s...i love tech, try and fill me with as much possible :smile:
