Money vs Horsepower
If the oil holes weren't drilled in the lifter bushings before being installed I don't think you'll be able to drill them. Run the solid flat tappet, sell what you have. Sorry though the cam is kind of small for me. I'm still thinking about the lifters but you might be able to make a better deal with someone as a package. If you don't sell them let me know. I don't need them right now so it's not a big deal but having spares is always a good idea.
No problem! I didn't really put them up for sale yet, but I probably will this weekend. Your thinking goes right along with mine, sometime in the future maybe I'll freshen the engine up and go with a roller. This year I'd just like to enjoy it.
I'd be willing to bet that a guy could put the holes in with the kit for the R-3's
My block wasn't drilled so I used it and got creative with the drill.....the fixture is set up for a 3/16ths bit , but I took a #2 center drill to start them and finished with a .093 ( 3/32 " ) and it worked like a champ.
The fixture will drop in a .904 bore and the geometry should be close from the top of the bushing compared to the top of the taller R-3 lifter boss.
I have to check, but I'm pretty sure my bushings weren't drilled. That looks like it would work pretty good, from my limited experience, but I'd have to say that I doubt I'd be comfortable doing it. I didn't even know there was a fixture like that! So many different ideas...
I suggest reading up on the effects a cam has on dynamic compression prior to purchasing a cam.
That is a good idea. If I get the chance to tinker on the computer tonight, I will try some different ideas. I think my compression will work with the aluminum heads, but I will def have to watch the timing and octane.
The roller cam was specd according to what I told Bullet, and I think that from the info I gave them about my car they came really close to what I want. When you were talking about .050 vs advertised, thats basically how I try to picture the lobe in my mind according to the numbers and lift. The solid flat was specd according to the info I gave Lunati, and my plans did change a bit from the roller to the solid. Lunati seems to think that the solid would do good with my 11.5, edelbrock heads, victor 340, tti header, 3500 stall, and 3.55 or 3.73 gears. Not the optimum combo for the dragstrip, but I still highly doubt that with the stroker it is going to be soggy on low end. I didn't see this cam in their catalog until they showed it to me, otherwise I would have probably chosen it. It appears to be a new cam, on the Voodoo line, Summit doesn't even have a good listing on it.
