I'll have to get you the Lunati part number(My catalog is still at work), but I have a cam I make on both 107 and 110 LSA. For about 10 years I made it only on 107, and a lot of them went into cars just like yours, CR, converter, rear gear. This cam is the real thing. I had a man with a bracket 468 Camaro, running 10.10s with a West Coast cam. He had to re-do his fuel system(Haven't we heard all this before?), and after re-degreeing the cam, new rings and bearings, he sent me a picture of him launching, with a 9.18 on the window.
The cam specs are: 286/296 at .020, 255/264 at .050, .685/.680 gross valve lift, and 107 LSA, for the aggressive idle and hard launch, quickest ETs, for a more streetable idle and drive-ability, 110 LSA. The 107 I always recommended 6° to 7° advance(100°-101° ATDC ICL), the 110 just 4° to 6°(104°-106° ATDC ICL).
Another user had the 107 in a most beautiful Street Roadster(Made some magazines), he put about 3500 miles a year on it, and ran 8.90s with a small shot of NO2....
Hope this one meets your requirements, if not, or more questions, just ask away....

UDHarold Hi Harold, What do you think that Roller would do for my combo? Please let me know if you see this post.
Thanks,
p.s. just received my 9.5" 4500 stall from BTE...

Add another 60 BHP and 30 ftlbs of torque.....
And the 107 LSA would add some more, at the cost of a 1000-1200 rpm idle....
Happy New Year!

Harold Harold, Any problem running this on the street as a weekend only cruiser? What about those 120 mile round trips to the track? I am sure this is as reliable as all your cams seem to be.
What alse would I have to change to run this cam? i.e. dust gear? roller rockers, springs etc...
Happy new year to you too!
