Well that is the ultimate question and one that I was also going to get you to touch on, the pros and cons. I was thinking of a flat tappet from a money point of view. I was thinking this route was better for me because I have the correct length push rods,using ford racing roller rocker arms, and may not have to up grade the valve springs from what I have now. If I go roller,then complete valve train will need upgrading.And how important is it having the valve spring seat cups? should I upgrade?
In comparing a flat tappet to a roller camshaft, both the same spec, would the roller produce a flater torque curve, or would it just flat out make more power all around over the flat tappet.I'm not building a race engine just one for the street but looking for that torque kick and as you put it, good street manners.But I'm thinking from the reliablity point of view, the flat tappet is the better way ( I'm worried about the roller needle bearings failing).
Your opinion on this is very welcome, thanks Mark
