Back when I was running I had 947 Comp springs triples, they were set up tight 1.850 were 2.00 340 to 350 on seat. They would last two seasons or 200 runs without a problem with 9200 rpm shifts, pushrods are dual taper 7/16. It all depens on your camshaft and how everything is set up in your valvetrain. I was told a long time ago you can't put enough spring on your motor along as you good parts to go along with them. Tom
