what is everybodys opinion on cam,rod,main,bearings.Im running a streetable 396
i try to use king bearings ACL make good bearings clevite 77 p bearings are ok . on the cam bearings i like dura bonds .all them bearings work good for a mild engine .for hi hp past 600 hp i use diffrent bearings first off they are H bearings and like the kings or speed pro 3/4 mains and other as well. there is very few bearings that i will not use on stock to mild builds .checking for oil running clearance and finsh on the crank and housing bore check out on the small side spec. some companys have dif ways of making bearings and holding size so i like the kings as they seam to hold spec better then some like clevite bearing and feds now on the box is speed pro . i have seen 0003 taper and 0004 bearing size in one set of mains in feds after getting the housing bores better then 0002 i realy get piss off on bearings that are out 0003 and have taper to but i like the 3/4 oil mains for bbc so i keep sets on hand and hand fit them .i hope speed pro has work on manufacturing. but the kings have not let me down for stock use as well as the H race bearings so far . and every thing needs to be clean clean clean
i bought some clevite 77 cam bearings and they are rated h cam bearing. What ill do is check to see if they are true or not if they are ill use them.And what are u talking about when u say 3/4 oil mains are u talking about the hole or the groove in the bearing itself ?thanx Pat
there is a 3/4 groove you should not need to use them on lower power engine for mild use they are abit $$ . i never used a H cam bearing for the bbc or seen one . i have used the durabonds ch 12 and gmp-12 for world blocks that make over 800+hp never seen a need to use any thing other then them .i like the the kings for oem use for mild builds and the clevites P are ok to . thats all you need for what your doing is a clevite 77. H bearings is for race use only less you have a large radius crank i have used them on the street but with big cranks large radius cranks .if your asking how i check them for size. i use a dial bore gage that reads in 0001 i use a 2-3 inch mic .i set off of the crank journal size. zero it to the size of journal. then with housing bore with bearings in block or rods tq up that tells me how much oil clearance i have and i move the bearing size to get were i what or if grinding the crank i grind crank to a size for oil clearance .i want but first i start by checkin houseing bores to be in spec on the small size for hi bearing crush this holds the bearing better in housing bore helps with the retentionQuote:

they not top on my list i have seen them move and will start to flake as well as other s if you run them loose they hold up better there to hard when you load them very hard you need more room .the V bearing is the old vanderell with lead indium that move better then the hard H clevite the kings hold up good to the old vanderells were junk before they went under . crower sold them put there name on them they did not hold up well, i had a set come part in a engine from just sitting :eek: i am sure there better now clevitte makes them now but it hard to beat kingsQuote:
