My question is, can I put a 6" balancer on my 350 cu. in. post 1986 small block engine. Right now the balancer I've got is 8 inches. I've heard about internal balance and external balance crankshafts for the small blocks, but how do you tell the difference between the two. Speedway sells a 6" balancer for internally balanced engines. I would like to get a little more clearance for my tie rod on the 29. Right now I've got 1.75 inches at ride hieght and would like to get about 2.50 to 2.75. I hate to buy dropped steering arms if I don't have to. Your expertise is requested. Thanks.
