Nice info as always. So after watching the last 2 vid it would seem that I should be fine to run a standard factory rockers with my 268h-10 since its lift is only .494
Rocker geometry, roller rocker tip to valve tip contact patch and push rod lengths should also be considered. Ideally you'd want an adjustable push rod, set the push rod length to suit your half a turn preload, then use blue dye on valve tip and rotate motor until valve opens then closes and check the contact patch. Then buy the corret length push rods to suit. Only problem is this will not work with the lifters un primed. You'd usually use a solid lifter to do this checking while the motor is getting built with the intake removed.
We did a lot of that stuff in the earlier videos on the motor already to check pushrod length and geometry we have a few different adjustable rods and a few full sets too of old school manton rods. We will make more videos on that stuff when we go to a stud which is where it matters because the geometry is completely lost. We remove the lifter cup and make it solid otherwise two different lifters usually have different installed heights on plungers.
@@thebrisbanebrothers8332 we will have to do a video better explaining when you actually need to check contact sweep and pushrod Length but for this set up it's not necessary as nothing is changing from factory dimensions within the valve train, same lifter height and plunge, pushrod Length and rocker ratio and height. If the heads have been machined to suit adjustable roller rockers or using lifters with a unique installed height only then will checking sweep be important
Hi guys love your videos wish there was more of them and a bit longer great information I was just wondering what temperature are you guys running in your thermostat in your Cleveland's I am running the correct thermostat for the cleveland with the restricor plate 82c you can get a 92c one just wondering what your opinion was cheers
