188/220 "drop in" cam

i am running one in my 99. it was installed a 99 center line. worked fine, but now that i am building a new head and it will be decked. idk what to do. i dont want to flycut. any help?
 
compensate with thicker head gasket, recessed valves, or depending on how much is taken off you many not have to worry with the smaller rocker ratio

I would first say CALL THE MANUFACTURER and discuss. Then if it don't work out, start a thread and bash their ballz to the ceiling fan...but that just me.

I've had somebody's cam laying on the floor next to me for the last two months or so. I'm hoping to git to it in the next couple of weeks.

Ya reckon I ought to start pissing & moaning now?

I did a "Search" but couldn't find anything. :confused:
 
When I change the cam in mine, I want a 'slide in cam'.

Too much work to take the motor out, stand it on end to 'DROP it in!!!!!!
 
Mine was checked today. He had .100 of clay on the piston and did not touch so my valve clearance is more than required. My protrusion is .015 and valve recession is .055 with .035 deep reliefs in piston. Looks like it would have easily cleared without the reliefs. Tomorrow he will degree in the cam and put an indicator on the valve to see an exact number.
 
Just checked mine today. 97 block, 06 head, 188/220, stock thickness head gasket( I believe .055??), .045 valve recession. Intakes are .082-.083.

Buyer do your fukking homework, Seller put out a good fukking product.

LOL and check PTV. I think it's a good product so long as the buyer is informed they must check clearance. :rules:
 
Mine got degreed a couple of days ago. Guy wanted to make a tool for checking it out of an old push rod and a bushing. Seemed to work very well. Cam was really close(less than 1/2 degree), and clearance was just over .110 with the shallow reliefs i have(I told him if it was over .1 not to worry about exact numbers). A bit of extra labor than didn't show any problems, but good to know. .035 reliefs won't shave too much compression so I'm not sorry i took the precaution. I won't have anything to compare to with this cam setup as far as spoolup goes with it being a 6.7 but as long as it doesn't spool slower than the 5.9 I will be happy. I'm hoping the cam and extra cu/in will make up for the larger valves and porting on the bottom end power.

Sooo....does anyone have the formula or description on how to check PTV clearances? I was planning on running the same cam this thread was started on in my 12v without cut pistons. Much appreciated.

Customer of mine bought a truck with this famous cam. Pulled the engine apart and every piston looked like this.
