Need some input here...I run my motors hard but not often..sooo ive this roller cam and lifters id like to use, only concern is its a vintage cam ground on an iron core...

Also the lifters are a .750 roller where all the comps ive used I think are .800..

I looked on google and it dont seem to be a huge issue.

However I was thinking some of the older more exp. crowd might know more on this topic....Thanks.

older yes more experienced no. run it!. It's not doing you any good performance wise or financially just sitting there in your stash. It's in your head you know you want to. Set it up/run it & let us know how it turns out.

It's in your head you know you want to.

Actually I dont know what I want to do with it...I was told it was junk, however the same person was willing to spec and sell me a better camshaft.

I really would like to use it esp. budget wise but if im gonna jack somthing using it I wont.

Would I run a diff spring pressure vs a std modern roller cam????

You can have the cam reground reground cheaply. Do that and get the specs you want. The billit is the expensive part.
