I´m running a flat tappet cam in a roller cam block.
I did a pushrod length check and the stock length hardened ones I
had fitted perfectly.

See post #60! Like Malc just said, too- stock length flat tappet pushrods are about 7.8" long, and that's where you start.

Yes, that's the stock length and it should be very close to the length you need. The exact length can be determined by using a homemade adjustable pushrod (example shown below), or by following the instructions from whatever pushrod supplier you decide to use.

Cloyes is a very good quality gear & chain set! Isn't there any where you can get push rods close? A Wrecking yard or boat yard The Volvo v8 marine engine is a Chevy 350 with volvo valve covers check at a boat repair shop and see if they have the 7.8 push rods. With all the water there LOL, there should be a place that repairs boats! many boats ran 327s & 350 engines!

CarCraft.

"It's worth discussing the fact that the rocker tip is actually quite busy across the valve-stem tip. Even with proper pushrod length, the rocker tip starts from the inboard side of the rocker. As lift begins, the rocker tip moves toward the center of the valve tip, approaching the middle of the valve at approximately half of maximum valve lift. As lift continues, the rocker tip moves past the valve tip's center toward the outboard edge of the valve stem at max lift. Then as the valve begins to close, the rocker tip retraces its movement back to where it began. In essence, the rocker tip sweeps across the valve-stem tip and then returns. This is what the rocker tip does with proper pushrod length. With either too-short or too-long pushrods, the roller tip starts in the wrong position and travels much farther. This can lead to all kinds of dangerous situations, all of which can also create valvetrain problems."

Install on one of the front rockers and watch the rocker tip as you rotate the motor.
