what is the good and bad points of roller cam bearings? i know the block has to be machined for them. do you have to run a special cam or can you run a regular solid cam? how much do they cost and how long do they last?

Unfortunately , to run a regular flat tappet cam with roller cam bearing's is a very expensive venture . There are only two way's to run a flat tappet cam with roller cam bearing's . Number 1 , is to use a Winston Cup type cam , which will cost you in the neighborhood of around $900.00. The second choice , though still not too economical , is to have a standard cam sleeved on the journals , then ground back down to size . The sleeving and custom cam grind would cost somewhere around $500.00 . It's funny that you mention this topic at this time ! We spoke with Crower today about sleeving a cam for a customer who is using a used Cup block .

In my opinion , on the average circle track engine and the average guy's budget , roller cam bearing's are not a good option , even with using roller cam's . The cost of machine work , and the price of the bearing's outweigh the horse power gain's in my opinion . But if your trying to squeeze every last horse power out of an engine , like the Cup teams , then they are a cheap horse power gain , though minimal .
