I would think that you’d want something like a 236/[email protected] on a 115LSA if you’ve got a decent gear in it. Otherwise, stay close to stock.

Never thought of that. Possibly so unless the lifter length compensates for the preload adjustment.

Yup: Hydraulic=different length pushrods. Please don't use a repro camshaft, it will give up probably 30HP compared to the 270S and give nothing in return. I have a dyno test in a magazine somewhere stating that but I'm too lazy to find it.

I’m a solid roller guy but if I had to use a flat tappet cam, I’d use a solid flat tappet, edm oil through light weight tool steel Lifters to give it every chance to live.

That’s clever! Is this a passage from the oil gallery ring to the center of the lifter and another lengthwise leaving the face somewhere? Seems like even a little hole would bleed off a lot of oil and pressure x16. Have you done it before?

My deceased brother left a "Street Hemi 284" cam. It will go into my future 413 sonic ram motor.

I thought Mopar lifters had a larger diameter than any other manufacturer and theirs would flop around in Mopar lifter bores.
The post in response to Nate S about EDM hole. Note it was a chevy lifter so someone doesn't mistake it for a mopar lifter. Yes mopar lifters are larger.

Sonic Ram is a wedge, I assume that it's a wedge cam ground to Hemi cam specifications. A Hemi cam won't work in a wedge.

I ran a set of those Howards EDM lifters in my 472, no issues. I bought them about 10 years ago so who knows what they're like now.

I am pretty sure I still have one of the Mopar Performance reproduction street hemi cams on the shelf. Collected it several years ago when I used to work there. It is the hydraulic version, nothing fancy just a stock replacement cam. I'd sell it. Give me a shout if interested.
