Ran a model of the UD 288/296 110 and the Crower 60919, the curves pretty much overlay one another. This with a 462, 10.5:1, dual plane, both with 1.65 rockers, and stock edlebrock D ports flowing 262 @ .600 and 157 @ .600 (as per Edelbrock literature). These cams seem to perform about the same, build torque about the same, and fall off about the same. I believe the 60919 is the bigger cam and has always been recommended with rhodes lifters especially in this thread. This thread seems to indicate the 288/296 has better street manners.

Q: Is my observation of these cams being essentially the same performance wise correct for the above example?

Q: Is my observation of the 288/296 110 being more street friendly correct?

I have 90% of the items to build my 462 this winter, which includes the 60919, edel heads, crower hft lifters, performer rpm intake, etc sitting on the shelf. The car has a 2500 stall (possibly to small for the 60919), and 3.42 gears. Its a 68 firebird.

After reading this I have a little reservation on using the 60919 with the 2500 converter, 3.42 gears, and standard HFT lifters (the ticking will drive me nuts). Will the UD grind suit a little better without the use of rhodes on the 60919?

If I recall correctly you have a 1975 557 block, correct?
This is like a case study of how a 557 will hold up with a longer stroke and some hard runs, with traction.
