Hi,
Is there any possible way to determine pushrod length without a checking tool? Is it possible to determine the pushrod length based on specific modifications? My engine is a 1969 351W with the following modifications:
1. Edelbrock 60229 Performer RPM Heads 60cc Chamber, 170cc Intake Runner,

2. Comp Cams k35-414-3 Magnum Hydraulic Cam and Lifter Kit
Cam, Lifters, Valvetrain, Hydraulic Flat Tappet, Advertised Duration 270/270, Lift .500/.500

3. Proform rocker arms, 3/8 in. Stud Mount, Full Roller, Aluminum, 1.6 Ratio

Using the stock pushrods (measuring 8.14 in) caused a set back in my 1969 rebuild. With less than 5 km on the new rebuilt engine, the cam got damaged and one of the pushrods got bent. I also noticed that the guide plates were eating at the stock pushrods. I know one reason why the guide plates are eating at the pushrods is because the stock pushrods aren't hardened steel. But, I think more importantly is that the pushrods are the wrong length.
Do you guys think the stock pushrods are too short or too long?
Are there any members here with the same modificatins that can help me determine pushrod length?
I know getting the pushrod measuring tool is the sure way to go. Unfortunately, getting the tool will set me back another 3-4 weeks since I am in Laos.
Any help would be appreciated. Thanks.
