Which lifters for Boosted apps?
Which lifters for Boosted apps? Hey guys, just curious what you are running for lifters. I will be buying a EPP Blower cam for my pretty much stock motor with 317 heads. I saw Pro Magnum lifters but it needs to be on an adjustable valvetrain and I don't want to upgrade rockers, etc if I don't have to.. Any recommendations for a good replacement? Mine are ticking
My builder talked me into the new Comp Cams short stroke race hydraulic lifters. I paid 10% over cost and they were still about $450. But I'm using a big 242/248 .624/.624 cam in my 370 and will be running 15+ pounds of boost and spinning it to 7500rpm.
I'm also building an all forged 370 in an iron block, and planning to stuff 15+ PSI through it...I have a power goal, but I think it might be a little too ambitious...my main focus when building the engine so far has been selecting the strongest parts possible within the specs I want, so I'm curious whats your goal is.
How much power are you looking to put to the wheels?

Which lifters you use should be determined by how many RPM's you intend to spin, weight of the valve train and the base circle on the cam. It doesn't mater how much power you make, whether it is a nitrous or boost application.
I'm no cam expert but my understanding is that as they get into the higher lift cam lobe designs, they have to reduce the base circle of the cam so that it still fits in the hole. Once that base circle starts getting too small, you start running the risk of the lifter coming too far out of the cup causing it to spin and wiping out the cam. I have run stock rockers and LS7 lifters to 7600 RPM and .625 lift without issue. For anything higher lift, I would feel more comfortable with a longer lifter body like the Morels.

Did you buy the set with the link bars? I would assume they also drop right in, without the lifter trays?
