titanium vs. stainless
 

What is the advantage of titanium over a stainless valve? My motor is 377 sbc with 18* gm heads. It needs freshened and i dont know if i want to spend the money for new tit. valves,it's just a bracket motor. what would i lose E.T. wise? Horsepower wise?

I'm not an expert on this, but I've been told if you are not going to run your engine over 7000 rpms don't waste your money on titanium. I do know they make your valve springs live longer.

I do spin it preety high about 8,000 to 8,200 thur the lights.

If the funds are there, then you probably should consider titanium. JMO

I have also heard of guys running hollw stemmed stainless valves as a replacement for titanium to help keep the weight down. I think I am going to try them on my new motor.

From what I understand it is a weight issue on high rpm engines. On my BBC I have titanium 2.400 intakes and stainless 1.84 exhaust and the stainless exhaust valve is heavier than the titanium intake valve. I also run mine between 8000-8200 rpm.

Why turn your bracket motor that high anyway?

Weight combined with strength. It's another level you can buy into.

Of course I will mention the obvious - run smaller stem (titanium) valves, with titanium retainers, a rev kit and smaller OD pushrods.

This is the diet package for dependibility and high RPM's.

I respectfully disagree about the pushrods.
I don't care if I give up some weight... big pushrods help more than they could hurt...and the weight of the pushrod isn't really a factor since it isn't controlled by the spring...not directly.

X2 with Tod. Sometimes there is good weight.
