They take the std. or extra wide cam bearings...not roller. The A460 block's lifter bores never have required honing. One may or may not have to hone the main bearing housing bores....depends on the required oil clearance, shaft dia. , etc.Out of curiosity are they still for regular cam bearings?
If my memory is correct, do you still need to hone the mains and lifters?
Thanks in advance!!
If you want to run a 4.440" bore you need the A460 block...not the A460BB which is ~ 4.490" to be honed to 4.500" bore.Lem, not to sound stupid....is that roughly what a 4.440 bore would be honed to? Will any of the A460 blocks work with a 4.440 bore? And the TSF 18 bolt heads? I know, I'm still learning this stuff. Thanks!
Thanks! With all the research I have done those were the two things that didn't make sense.... but now they do!You can run the steel roller cams with std. style bearings or the rollerized style bearings. The 'roller' bearings require the cam tunnell to be bored bigger....expensive. Most applications do not require the roller deal and will be just fine with the extra wide bearings.
The 18 bolt thing is for the C460 & newer TFS A460 style heads. You can put your 10 bolt heads on the 18 bolt blocks ....no problem.
