hey guys, i want to put in a manual in my 70 chally, i dont care if its new or old, i was planning on putting in a stroker kit, still undecided. if a 572 can work on a stock block then i would definatley get a 572, whichever is the largest that will work on a stock block is which i will get. so the tranny will need to be able to support the output of whatever kit i get.
