LT1 camshaft suggestions?

The LT1 is one of the most "under rated" engines built. They had to have the original, camshaft and the ALL the distributor main shaft and accelerator cam to run as designed.
Find all the original parts, especially the camshaft and dist internals, the properly jetted Holley and you won't be looking at very many tail lights at the drags and you'll get decent mileage...

Um, I’d take that bet. The LT-1 cam is a great piece but a properly chosen roller would walk all over it.

Yes...I'd run ya. Now the parts have to be comparable (lift for lift), streetable and on pump gas.
It took me a long time to realize the potential of the LT1 cam, it was overshadowed by the big blocks in its day. But I never got beat by a big block car, I was beaten by a "fuelie" cam car a few times, but I realized he had more money in his motor than I had.
The important part was getting it properly tuned....
Thx for the offer!!!

Here you go. I just bought one........

As some others here can attest to, I love this cam.

In fact, I recently put a similar cam (but not the same....tighter lobe centers) and will probably be changing that out for this one.

I just works. Makes power past 7000 (provided everything else in the package is up to the task) and has manners off idle.

Hope that helps!

Napa what do you mean, it has manners off idle. I would like to find a cam that pulls like the LT1 or better and has a lumpy idle like the 572-720. I had a Sig Erson part # written down from years ago that I wanted to try, but of course now I can't find it.

What I meant by that, is you don't need to slide the clutch at all on an LT-1 cam. No cam burble at 2000 rpm (hence no jerking in a stick car). I can give you the cam part number that is currently in my 327. While I am fine with rough idles, it's not a primary requirement for me.

Here is the 327 I just finished. 10.5:1, pocket ported 461's, Z28 springs. Idle @ 1100 rpm Nothing fancy. Good to 7000.

With it's current cam (which I'll get you the PN) it carries about 400 lbs of torque from 3500 to 5500. It does require me to slide the clutch a bit more and have a bit more initial timing screwed in than I'd like. I am going to get my wide band sniffer on it this week and see if I can tune around it. Otherwise like I had mentioned, I am going back to the stock LT-1 cam. I've built this combination before in a fuel injected 327 and it just plain works!
