Camshaft help!

Ive got a stock long block 5.0, (stock upper and lower intake as well) and I have an e cam. The motor is a 91 with 51500 on the clock, NOT 151500. I was wondering if I could just slide the cam in without having to change anything in the heads such as lifters, pushrods and springs. If I DO, please provide what exactly the part is and also a reputable place to purchase from.

Thank you

Normally you would use new lifters since the old ones could cause premature wear of a new cam!!! As far as pushrods and springs it depends on the cam specs but if it was me I would buy new hardened pushrods and spring to match the cam!!!

I believe your roller rockers should be fine, but just remember to check piston to valve clearance!

You should change the lifters and valve springs at the minimum.
You can visually check the pushrods for damage and roll them on a flat surface to see if they are bent.
You can get your parts at American Muscle or LRS
They are site sponsors and will likely give you the best deal.

except AM doesnt sell springs... i'll probably get them from LRS. so at minimum, lifters and springs... will new factory springs work? The E cam is only .054 bigger lift @ the valve than stock.

They should work fine.
Is the price difference high enough to make you want to use stock springs?

Most people do not think about valve springs as having much effect on how their vehicle performs, but they do have a significant impact.
A use weakened, fatigued set of valve springs or a set that has inadequate seat pressure will not keep the valves sealed up properly leading to leaking valves that allow combustion gasses to escape to early causing a drop in cylinder pressure and reduced performance and economy.
