Can a hydraulic cam profile ( specs) be converted over to a solid cam grind ?

Sure. It would have to be ground just a little bigger to make up for the amount of lift and duration lost with the lash of a solid cam vs hyd. Is that what your asking??

Just put solid lifters on that cam and lash it at .002 and run it.

It's done all the time. You can put solid rollers on a hydraulic core. It's not even a new thing. Been done for years. It will make more HP, RPM higher and be just as reliable.

Screw hydraulic lifters. All of them.

Lash it at .002 and go.

Hydraulic roller core, solid lifter.

I'm confused here..this a hydraulic flat tappet cam ,not a hydraulic roller cam , maybe I can just have a cam ground to the same specs as a solid lifter type .

Ask your cam guy about the relative accel of hyd vs solid ramps, but hold the phone away from your ear because he's going to yell at you.

Ahhh [censored], my bad, I thought you said you had a hydraulic ROLLER cam.


Need to brush up on my reading comprehension.

I went back a reread the first post. I have no idea where I got the roller cam idea from.

So no, don't put a solid flat tappet on a hydraulic grind.

But you can use solid ROLLER lifters on a hydraulic ROLLER cam.

solid lifter flat tappet cams with have a more aggressive lift profile than an equivalent hydraulic cam. this will add more power down low and add a few rpm to the top end. you can get a cam ground similar to what you have now, but I bet there are better cams already ground, you just have to pick the right one.

your cam specs are pretty common, but you don't say what you want to do with the car or why you want a solid cam? maybe a better hydraulic is in order and save yourself some valve lashing.

Just talk to Dwayne Porter (fast68plymouth) who already responded on here. He is one of the best cam person's out there and can grind a custom cam for you. I used a solid flat tappet that I got from Dwayne as I told him my car was a pump gas street car and I wanted a solid cam that had a nice kinda lumpy idle and made good power and had to keep my cyl pressure pump gas friendly. He speced the whole cam as he speced the lift , duration , LSA and gave me the recomended installed centerline. He had the cam ground for me to the specs he recomended and it has been working great for over 5 years in my eng. I have been a tech all my life and know a good bit about cams but I am no pro like Dwayne is when it comes to cams. He does it all the time everyday and every car I see with his cams in them always run great. You cant go wrong by calling and talking to Dwayne as you can call him at 802-951-1955. Good luck with it , Ron
