If you need power mostly under 3000rpm you can leave the cam stock or maybe go to a 254 grind, at the most.
The stock 261 solid lifter grind gives peak hp at 3300 rpm!
Pretty good for an engine with only 4 main bearings...
You can call Delta Cams in Tacoma.
They have various grind patterns for the 235/261 and can give you expert advice, which grind works best for you and why.
Delta makes the popular 'bulldog' grind with an asymmetrical 254/264 in/ex duration, offered by a few vendors.
254 at the intake gives good idle and 264 at the exhaust extends the hp peak beyond 3500rpm.
A good cam for racing while still giving good idle, but not so ideal for mostly street/freeway use below 3000rpm.
Hydraulics have a tendency to float at higher rpm, but should be fine under 3500rpm.
Solid lifters can be tweaked for power at higher rpm.
Because of the .060 overbore on my 261 I went with Delta's solid lifter grind of 254 in/ex with .433 lift and about 110 lobe sep.
I have a 3.55 rear with original 3 speed and typically drive around 65mph at 2800 rpm on the freeways.
This cam has still plenty power left for passing and climbing up mountains without losing power.
Also a great cam for hauling - Delta calls it the RV grind.
Read the famous McGurk article I posted on your previous thread.
It lists various cam specs used for the tests and the graphs show clearly the effect they have on the power band of the 261.
