We ship stuff all over the world and dont send anything out in just a plasitc box with room to move around. If they can bounce around inside the box they will surely get loose. We always bubble wrap and cut the box to shape so there is no room for it to get damaged inside the box. Unless the box is crushed. With lifters they can pretty much go thru hell sep for knocking into each other.
Good time to get a recommendation from comp and the right lifter that will take the rpm a higher lift/duration cam will produce. if the cam will push the engine above 6000 rpm or more than 600 lift you can imagine the lifter for a normal setup wont do the job.
COMP Cams: Short Travel Link Bar Retro-Fit Hyd. Roller Lifters; GM SBC
Certainly not cheap. But should hold to 7K + I think they are good for 8K rpm but dont quote me. Comp also sells a tall lifter for use on roller blocks that use like bars to get past the taller lifter boss. So still might be worth talking to them to see what they can recommend for the cam and the small base circle and if the lifter bosses are tall may be worth it to ask what works.
Hope this helps.
I was on the phone with Summit and they were extremely accommodating. Normally, Howards lifters are in a plastic box with a foam insert and individual cutouts for the lifters to bed in. But, some nit wit only used some packing pillows and the plastic case popped open, spilling the lifters all over inside the box. I didn't even examine them. I didn't want them. Could be all kinds of dirt inside that box. They are 2 day airing me another set that is supposed to be here on Friday, but I have not received a tracking number yet. Gonna piss me off if they aren't here on time. I have help on Saturday morning ready to go.
Did talk to Comp cams and the guy told me this cam does not need a short travel lifter. He said it should be fine with the Howards and told me that if I didn't want the comp lifters he would go with Howards. He says they are as good as anything out there for street use. My son has them with a large Lunati (580ish lift, 250s duration) and he sings that thing up to 7k for extended periods. Never heard a motor sound so sweet at that RPM. I'm at .600 even so there isn't much difference between the two of us. I've had my Edelbrocks at 7k and they were bad before I revved it.
