This is a question asking opinions on for a friend he works over seas and not able to post. He has a 482 bbc,with 14/71 blower and alcohol injection. Engine was built by a reputable company,ran the motor for a few passes to get a baseline and decided he wanted to go with a set of AJPE billet heads.Took the motor back to them to let them make the changes. Switched to [email protected] shaft setup and new pushrods. when he picked the motor up the first thing he noticed was it had 3/8 pushrods in it which he questioned them about,and they assured him it would be fine.Well first burnout it drops a cylinder,pull valvecover and find 2 bent pushrods and a busted lifter. Long story short not bashing engine builder just wanting opinions on what size pushrods you guys suggest.I know need more details but trying to keep short as possible, spring pressure around 380 on the seat and 1100 open. thanks in advance for any replys.
