Pushrod length
First sorry for my english.
Im about to check the pushrod length due to new heads and cam.
But i whas to hurry and mounted the heads and intake before i know that i whas supposed to use a solid lifter instead of the hyd lifter when checking the pushrod length.
Well whats done is done..
I read on the internet about 2 diffrent methods to do this.
1:http://www.circletrack.com/techartic...ushrod_length/
This i tried but as i got hyd lifter installed i cant get a consistent reslut on my rockers, but if i take a avrage it seem pretty much in the vavle tip center.
2: Or this. Mount the rocker when the lifter is at the base of the cam, markt the vavletip with a pen. Then viggle the rocker left to right and se that its center or a tiny bit against the intake side off the valve tip . This i did and can confirm its center.
I also tried this device.

But that jsut made it even more confused. Accoring to that i got 0.078" to long pushrods. BUT if i use my adjs pushrod and take away 0.078" the other 2 tests fails. So i dunno?
Any tips are whery welcomed
Thanks
