================================================================



I'd like to stay mechanical 'cause I just LIKE 'em


But what are my options with these roller lifters?


Pushrods? Anyone dealt with these rollers and 273 cast rockers, IE pushrod length?


Cam? If I use these lifters, what's a good cam? Like to stay with something "equivalent" to the old 340 cam "in modern form"


This is a VERY low budget engine. I was just going to re-ring a core I have, but for this money, I could not pass it up.



Of course I don't know what cam is in there NOW, but surely a "truck" stocker etc.
