I do agree that I think you could use more cam. There is a grind going in my 383 that has exceptional results...it's big and not likely to pass emissions, the duration @.050 is 242/252, and the lift with 1.6RRs is in the .56x-.57x range, I don't have the card in front of me. There is also the GM847 cam that has been getting very good results as well, it has a little less duration at 234/242@.050 and little more lift at .574/.595 w/1.6RRs. I think either of those would be a nice choice!

what LSA are those cams.when i build a stroker i'd like to keep it at 114 becaue of good idle characteristics and vacuum.i need to pass smog aswell.are all you LT1/L98 guys using 112's?i would think it would take a little more tuning to get it right.thanx in advance.

When I called AFR and spoke with them, they said I would need a 242/246 cam with at least .600 lift to get the most out of the 210-heads. Having driven in a TPIS 701 cam = 242/242 Solid roller, I would say they are right and I would go with at least the 701 cam.

I have a friend with a 383 using the AFR 190's, miniram, TPIS headers, etc, and he went with the ZZX cam (239/239). This car is a road racer only, but it put down 411 to the rear wheel. I't sounds bad as hell and runs as good as it sounds.

Mitch.
I am going to be going larger with my cam, I ran this past year. Its a Lunati billet piece that is noted in my signiture. If you would like to work something out, I think it could work out for both us.
The cam idles great and purrs like a kitten on the street. It suprised me, and the reason I am going to go even bigger and into more unchartered waters. I am surprised at how these larger inch motors take to relatively large cams.
I am going to venture into the 27X duration world maybe even 280s

And because I have a cast crank the Superram is better plus I think the 233/233 Hyd-roller will work fine with the Superam too.
I agreee with Jesse, the bigger cube engines wtih EFI really can handle more cam than one would expect, even the cam guys I have talked with are surprised at how much cam the EFI 's seem to handle.

Shinobi, you won't be passing emissions with the GM 847 cam. Its LSA is set at 112. I squeaked a comp 306 cam by emissions in an F body a couple times with its 230/244 specs or something like that, it too is ground on a 112. I doubt I can squeak that GM 847 cam through emissions. Maybe it could be done if I used the Alky trick, but even then I think it would be tough.

I am limited to .650 with the current springs I have. So I was going to call UD harold and see what he thinks would work in the .640 lift range.
Mitch. Let me know ASAP./ I also have a set of practically brand new hi-tech roller lifters that I ran for a very short period of time. I keep forgetting I have them and should sell them.
