Most Aggresive cam without shim under bucket?

[DenZel]

whats the highest lift you can do? and safely

my next step is cams + headwork

how important would it be to send the flow results to match the cam

currently making 237rwhp

i want to crack the 300rwhp mark with the cams + headwork

ofcourse changing to heavier duty valve springs too

wanting kelford cams + springs

experiences, results?

So hard to find when not many people play around with the 1uz na build

207-C ..??
These cams being billet the base circle is nice and fat. The same as Toyota made them..
They maybe still could have issues if engine was over reved and valve springs not upgraded or too soft.. They are under 50 Lb seat pressure after a few Klrs..
It's best to ask these guys...

I have Kelford cams and they supplied springs to suit the cams.

When we assembled the heads we found the springs were "coil binding" before full lift.

We ended up using Falcon XR6 springs.

If you plan on Kelford's springs make sure they undertake to refund your outlay if they bind.

I used BC1300 beehive springs with titanium retainers... As used in 2JGTE...

With s/steel one piece 2J valves, shimless buckets...
Installed height is the same as 2JGTE...

Yep.....Esp if Kelford say they are o/k.. I would fit some better valve springs .. The std springs are lucky to have 50Lb seat pressure..
Lextreme have springs...http://www.lextreme.com/Tundra-Valve-Springs.html
