Title: Bbc pushrod length roller cam.
Post by: Funkatation on November 09, 2015, 12:04:23 am

I installed a lunati voodoo retrofit roller cam in my big block and used a pushrod checker and came up with 8.280 and 7.300 for my pushrod lengths. That seems way shorter than stock and what most companies suggest for roller cams. I have 781 heads that I put larger valves in and the block was decked a little bit. Am I crazy here with these lengths? Seems off by .300.

Lunatic has a tech line. I would give them a call.
