Cast core crane solid roller

Now before anyone says it, I know these aren’t ideal. I would never buy one new. It’s not the specs I would choose But.. I purchased a old school built in 74 340. Has the typical dome trw’s and all the mods and parts a person could buy then. Full effort from back in the day. It has a crane r280/427-8 solid roller. It’s a cast unit. I’m putting together a car from all my spare leftover parts from over the yrs since I have it and for fun. Do I dare run this???? Calls for 170lb seat and 485lb open. Will have a good set of w2s, stock stroke, ram rod, cragars etc etc. A fun day 2 street machine.

I’m running a Racer Brown cast roller .660 lift cam in my 408 that Jim made for a buddy of mine and I bought from him. It’s gone 5.98 so far.

That’s all we ran back then. No problems.

Thanks, that’s what I wanted to hear. Pittsburg, how much spring pressures are you running? Closed and open.

Here’s the cam card. It’s on the bottom

Thank you much

You are very welcome
