Thought I would share some of what I had done recently. I recently built a new small block for my Z. Long story short, did everything correct to the T...correct oil, breakin time and rpm ect.... and had two seperate flat tappet cams go flat. So I found some information online where a couple guys were using roller lifters out of 2.2L gm motors, spiders and dog retainers out of later model v8 roller motors in early small blocks with a little machine work on the blocks. So I thought what the hell....I have already spent around $500 on cams and lifters at this point whats another couple 100 gonna hurt. So 49 cent used lifters from a 2.2L cavaleir motors. I already had the spider and retainers out of a later model roller motor and this is where im at.......
Good thing about this is that you can either use the conventional roller type cam or a retro type cam with just using the correct timing chain/gear and button...Im gonna order a cam this week and should have the motor assembled and running on a test stand before it goes in the car.
