I could show you want the profile should look like if you’re interested in running SR lifters on a HR profile. But I could pick a full SR profile out also. That Butler cam isn’t a good choice for this.

Ok, I will take your word for it. Looks like I need to go Hydraulic then. What do you feel would be the best Hydraulic lifter for this cam? Butler talks about measuring the base circle to the oil hole in the block with the cam installed. So, I guess I'll have to do that and then find the best one that fit those needs. What do you think is the best/strongest lifter out there that you would use? After all the axle and wheel sizes you were talking about, I'm figuring you may know what the best choice will be. Is there a brand that you like best. I don't have much experience with hydraulic; I usually only use solid. But this motor is just a mild streetcar for a friend. In the past ive used comp Crower and recently Bam. But I don't think Bam makes Hydraulic lifters or I would buy them. Back in 2004 I had some bad luck with a set of Comp rollers. The caps for the axles were walking out of them. I'm lucky I caught it. That was the last time that I used Hydraulic.
