For a street application - dont waste your money. Research this forum regarding problems with roller cams in SBM's.Is the return worth the added expense? I will have to learn some more about this.. I think I want it but not sure why I do.. LOL
After the switch...I had a hard time trying to talk myself into using a flat tappet again in my other motor..still on the fence. Its quite, like a sewing machine in fact..throttle response is the stuff dreams are made of..lolIs the return worth the added expense? I will have to learn some more about this.. I think I want it but not sure why I do.. LOL
Yep.
Springs, switch to 10 degree locks n retainers if solid roller. Price accordingly..180-300
Cam-300ish bucks
Roller lifters 300-1,000+
Crane coated steel gear for billet core 90.00
It can add up. I went through herbert cams and got a nice setup for less.
Ouch X 3The Herbert stuff looks really good on paper but they scare me. I went through THREE hydraulic flat tappets from them a few years ago and not one of them measured to the specs on the cam card. Not even close. Each one they took back, inspected and agreed with me. The third return, I asked for a refund. It was not a small difference, either.
To my knowledge there is 1 guy that grinds for a few different companies/brands and he always grinds them a little off, be it cause the specs were **** and wouldn't last or who knows. Engle does their own, but I think bullet uses him , the one guy, too.The Herbert stuff looks really good on paper but they scare me.

I knew his name once upon a time...
I have gotten cams suspect on the phone and when the cam showed up the card was not exactly what was spoken about on the phone. Sometimes what we want and what's actually going to work are 2 completely different things.
Then let me share you a bit of info...It was one of their off the shelf grinds.
Depends on how badly the bores are scored and what the requirement in clearance is between the Icon pistons and your present bore. IIRC, Icons are 2618 alloy forgings so they can run tighter than 4032 alloy. But usually the difference between hypereutectic and forgings of the same over size is significant enough to require re honing. So really, you’ll have to dismantle it and get it measured to know for sure.
