Glad you got to talk to Bob. I believe you will be happy with your choice.
Getting old just means you were smarter than some and luckier than others.

I installed Bobs cam in a friends Challenger 440/6 after he wiped a cam and I was amazed how well it ran. I think the secret to the cams success is a wide LSA and the short duration that seems to work well with STOCK exhaust manifolds and unported heads. After we installed the cam the car was taken to the track were it ran a 105 mph in the 1/4 spinn the tires for over 300ft. His car has 3.23 rear and a tight converter that also works well with Bobs cam. If you have a restoration type build with manifolds and stock heads ,valvetrain and converter and 3.23-3.55 rear this is a great cam. BTW, what the big secret ? His cam is a short duration with a wide LSA (113-115) and these specs are not really offered by any cam mfg. The Crower grind 32242 is also a great cam for a 440/6 with stock manifolds/valvetrain and probally one of the closest grinds to Bob Ks cam.
Thanks for the post, especially with regard to, "After we installed the cam the car was taken to the track were it ran a 105 mph in the 1/4 spinn the tires for over 300ft. His car has 3.23 rear and a tight converter that also works well with Bobs cam."
I'm curious now what size wheels and tires were on your friends car that he broke the tires loose for 300ft. with 3.23:1 gears?

All I can say is "Mr. Pack Six" cams work!
My 38000 lb. barge with the original beat-to-death unmolested short block complete with those big stupid 6BBL rods and cast rings has gone 12.58 @ 110 with his cam.
Cool!
Is that a 454 Chevelle LS6 you're beating on?
What's the rest of your package look like?
Stock heads?
Torque converter?
4.10:1?
etc...

And yes it's the original standard bore 440 motor and that's a LS6 454 Chevelle SS in the next lane.
All I did was install Bob's cam (he also worked some magic on the Holleys), did a valve job and installed a TTI exhaust. It's also a 4.10 Dana car.
TTI exhaust? Is that from the HP manifolds back?
Also, in that LS6 picture you posted, were you racing in Pure Stock Drags or other?
Thanks

Yes, I race my 6BBL Runner in the Pure Stocks, therefore it has the factory HP exhaust manifolds. Heck, I still run the dual point distributor.
The 18,000 mile 440 has led a hard life from the previous owners (Wayne State University and the engineering students pounding on it during the vehicle impact tests back in 1970-72).
