Camshaft questions, oh man.
Hey guys, here's what I have.
92 Chevy Silverado 4x4 non-z71
Engine
Late model, not sure the year, have'nt ran the castings, 350 Roller block.
Bored .060
stock style four valve relief pistons
standard rods/stroke
Not going for a racer or mud buggy or towing 8 horses.
I want a little bit bigger than stock cam but I would like to know the benefits of using a roller cam. Are they worth the money?
I want to use the stock heads,(from the 92 non roller 350), valves, valve springs pushrods etc.
I ran up on what seems to be a decent deal on a roller cam, lifters, lifter guides and retainer for around $150, its a used cam but low miles.
I have never used roller so Im not familiar with the pros and cons, any suggestions?
thanks
Dale
Oh, also, will a Vortec cam work in a non Vortec block?
Thanks again

Roller set ups use less friction. They work better in higher RPM. I took a stock cam out of a 2000 LS1 motor. It gave me 23 pony's. I went from a .467 lift to a .500 lift. Slight lope but really increased power!!

Thanks for the advice guys. Here's another question for you. How much lift and duration @ .050 is too much for GM TB Injection without using a chip mod? Also what would be too much if a fella wanted to use stock valves, springs, locks and retainers? And lastly, whats too much for a stock stall in a 700R4/4L60E? I want this thing to run like a ***** when I am done. I plan to degree in the cam too so my valve timing is exact. Thanks again.

Thanks for the input. I am gonna toss those ideas around. I have been out of high performance applications for so long, I dont remember much about putting things together where the numbers work to make the most HP and Torque. Man why did I ever quit building? Thanks guys.
Last question, are Vortec parts interchangeable with older small blocks?
