the only downside to Daily driving a car with a big cam is Valvetrain maintainence...Just means you will be checking springs or replacing springs more often and keeping an eye on the wear and tear of the other parts of the valvetrain for potential problems
Daily Driving my Car in my signature....(except for days when it rains cause I have no longer have wipers...and I dont drive it in the snow..LOL)
2001 Camaro...
cam is a 248/252 .649.646 112LSA+2
Manley dual springs good to .700 lift
Yank PY series racing converter - 5k stall speed..
drives and runs great on the street...
a good Tune makes all the difference in how it behaves...

Thanks for all the information
If your running a stock 10 bolt then you'll really need gears to go with the stall and cam. Which equals broken rear if it wheel hops or launching on sticky tires. You can drive one with stock gears but it will be lazy down low. Say untill mid 3k or 4k rpm's. If you are running stock heads it may be worse.

not necessarily...
I was running 11.2@122 on the stock 10 bolt with the 3.42 gears...and cutting a 1.5x 60ft
TCI 6x transmission and a big stall...

If you ease it out of the hole and feather the clutch, you can make it work for a long time...
It's when you start to hit the rear hard that you will break it...
And it honestly doesn't take a lot..
Manual trans + stock 10 bolt + hard launches = broken rear.

Verdad Gallardo big lope does not always mean big power.... it just means big overlap...
most of the time, assuming its not some random untested grind, anybody's off the shelf big cam will make bigger power up top...that is the nature of fluid and air dynamics in an engine.
valve events dictate everything...big duration does not necessarily mean big overlap
ICL and ECL play a very important part of that total amount of overlap..
a 236/242 cam...
112 ICL and 112 ECL is 15* of overlap...basically LSA 112 installed straight up..
110 ICL and ECL is 118 is 11* of overlap.... that is an LSA of 114 installed 4* advanced
both sound completely different, but have the same durations on the cam lobes...
the one with more overlap will sound more choppy and more wild...
the one with more overlap will also make more power up top, but at the sacrifice of a more peaky and narrower torque range
the one with less overlap will make less peak power, but will have a flatter and broader torque range..
both will peak around the same spot in the rpm range...just the one with more overlap will have higher peak #'s with a smaller powerband and the one with less overlap will have lower peak #'s with a more flat powerband
My point is that the OP does,nt have all the supporting parts for a big cam. He will be going from a near stock ride to a car with no low end to a perky top end.
