This question is directed to those that have cam-ed their lt1 and put a higher stall torque converter on the tranny. What kind of drivability do you have for longer trips. It goes with out saying, adding a cam and supporting mods with reduce gas mileage. I'm not worried about that, i just want to know if its a bad idea to take 2-4 hour road trips at highway speeds with a medium cam like cc503. Thanks for the input.

well the cc503 no issue. the torque converter with lets say a 3500 stall should be fine as long as your not haul %$^# to the area. the cc503 is a good DD cam cause of the low end torque for driveability around town. with a 3500 stall you should have no problem on the highway, probably end up sitting at 2200 with stock gears. the only real time when a torque converter heats up is doing a brake launch or always in the throttle. so basically your fine.

You will cruise at 2800-3000rpm at 75mph with 3.73s in the rear.

If thats doable for you, then thats really all that changes

3.73 gears will most likely get done. I have 4.10s in my 92 bird, big difference. Thanks for the input you guys.

How fast you figure he's gonna be driving?

I ask because those kind of RPMs is what I get with my 4.10 gears .

With a cam much bigger than the CC-503, I get my speed to 70-75 mph, flip on the cruise control and knock out 350-400 miles no problem.

With 3.73 gears and a 3000 stall TC, I'd knock out about 21 MPG with my Impala. With 4.10 gears and a 3600 TC, about 18 MPG.

They most telling factor in your gas mileage would be the quality of your tune.

My old heads/cam combo used to cruise 75mph at 2800-3000 rpm, that was both with a cheap ass mystery stall, and a circle D 4000, 3.73 rear gears. Was the same cruising rpm through both of the "tunes" I had on the car during that stage.

I would say the trans slippage has more to do with RPM than anything else, fairly certain mine was def hurt pretty bad.
