Quote: what kind of rpms do you think this engine is going to turn? or what are you feeling is safe with that hydraulic roller?
This engine HAS to turn 6700 rpm or it won't qualify in Ohio.
I have had plenty of experience with hydraulic rollers and zero issues with that kind of rpm level. The Scorpion lifters I am using this year are incredibly nice looking with a pushrod seat that is half an inch .5" higher than their solid rollers. The pushrod length on this particular combo is 7.2"--fairly short. With a set of PAC 1255's the rpm of 6700 should not be a problem. Whether or not it makes any meaningful power up there may be.J.Rob
What's the highest rpms you have turned with the hydraulic rollers? do you always use the Scorpion lifters?
The highest I have turned repetitively is 7000 rpm with hydraulic rollers (Hughes lifters/W2 combo)
I always use Scorpion lifters now that I am a dealer. I believe they are made by Johnson Hylift. The laser etching on the lifter body of their solids would indicate that. Scorpion products are real high quality and priced right IMO. I will put up a photo of the lifter. J.Rob
