CAMS ARE HERE!
So here's a pic of cam cap #3 sitting on top of the first cam I got. Note how it doesn't quite sit down all the way on the cam:
Thanks to Shane at DB Performance for helping me get this sorted so quickly! He measured the new cam when it came in and was doubtful it would fit...so I brought the cam cap up with me and it slid right on! It was hard even for several sets of calipers to decipher the difference, so who knows...maybe it was out of round or something?
New cams:
Got home, slapped them in immediately:
Enjoy them in there because they're coming right back out, time for some math!
The 4b11t has buckets that sit on top of the valvesprings, then the cam sits on top of the buckets, like a honda. You put the cams in, measure all 16 clearances, then take them out, measure all of the buckets that are out of spec (with the new cams, springs, valves, ported head, its not surprising!), then figure out if you either want to rearrange all of them and try to make them fit, order new ones, or a combination of the two.
I was able to bring all but 3 of the intake valves into spec (.008" +/- .001"), and the other 3 are only another .001" out of spec on the loose side. I would almost feel comfortable running them like this buuuut the exhaust side was just a mess. One had a gap of .003". The spec on that side is .012" +/- .001 so it was waaay out of spec.
So after some extra time with the outside micrometer, shop manual, I had to choose between
47 different tappets to order, all are stepped up about .0006" from each other (.005mm). The ones that were far off I ended up ordering two tappets each, just to be sure I don't have to wait for extras. At $8.50 a pop this was another quick $100+ down into this thing, but this *should* be the last thing I need to put everything back together! I paid an extra $20 to get them overnighted so its gonna be head down this weekend and see how far we get!
