What's the biggest cam anyone have without having to flycut the pistons.Want to put a 234/244 .614/.616 110 cam I have laying around in my car ,but don't know if I want to start grinding into the pistons.Give me some specs on your big cam insatlls!!!

 

 

I think the trex is the cam ur looking for!

 

Here's my experience. Yours may vary... Last fall I put a set of AFR 205's milled .010" on a Cometic .040" head gasket with a Comp XER 224/228 .581"/.588" @ 112lsa +2 advanced dot to dot. My pistons were 'out the hole' .004". I measured my P/V on the intake at .110" and on the exhaust .148". I recently pulled the heads and had them milled another .020" and set the cam installed at 112 degrees ICL (straight up, no advance). When I measured the old ICL I was a little before 109 degrees, ~108.5 degrees so I retarded the cam around 3.5 degrees. I measured my P/V at this point and had .060" on the intake, and .070" on the exhaust. I had to flycut to get my clearance on this small of a cam. I had a total of .030" milled and .012" thinner head gasket making for an effective .042" mill from stock. What I took from this experience was, there were too many variables to predict what my clearances would be based on just numbers. My cam was ground as advertised, but the accumulated clearances in the valvetrain had it advanced slightly more than dot to dot said it was. Then by changing the timing on the valve events I put the valves closer than I had originally. Your cam is much bigger than mine and if you are running anything other than stock heads with that lobe size and that tight of an LSA I would measure everything twice. I would measure it anyway, why take the chance of smashing the top of your motor for a few hours of extra work? You will also gain the peace of mind of knowing your clearances are correct or not.
