Hello, I'm looking for some suggestions/insight. I have 68 400 engine with 3.90 gears. As far as I know it is stock other than it has been bored .030 over. I am thinking about replacing the cam and I'm debating between an 068 and 041. I'm not building a race car, just looking for a little more performance. Can I even swap out my cam for an 041 or do I have to replace more parts due to the lift? Thanks.
Only RA and HO cars came with 3.90 gears in '68. You probably have a 068 cam in already.
I would double check what engine you have. Also, you may have more work there than you think. How long since the last rebuild? You open up the block you could be inviting yourself into more work and parts. You have to keep in mind the high compression needs to be reduced so you can use pumped gas
