New cam for my 385ci, suggestions? Been toying around the idea of getting a proper sized cam for my motor for a while now. Currently its running a 220/230 billet crane cam. Initially this was to pass emissions. Looking for something a bit bigger that would better suit my motor. But keep in mind this is a street car.
current setup:
385ci
11.1 comp
Canfield 225cc heads (ported)
LT4 intake (welded and ported)
58mm throttle body
2800rpm stall (will be swapped out for higher stall)
3.42 gears
Cheers!

If you are looking to go with a solid roller then I have a real nice street/strip cam that I am going to take out my 383 LT1 this week. My car ran 10.80@127mph on motor with this LE cam and my setup is very similar to yours. I have decided to get rid of the stock PCM so now I will be able to turn 7500+rpms and a cam change is in order. LMK Later

why such a large split when he probably has pretty good flowing heads? (i thought canfields were pretty solid) might build more torque with 4-6* split rather then 8-10.

Stock heads love a wide split, but with a strong exhaust port from an aftermarket head and a free flowing exhaust system you can bring the exhaust duration down and leave the intake the same to make the same hp with more low end tq.
Isky was a big fan of this.

You could give Advanced Induction a call...these guys are great to work with. They will even custom grind u a cam. But I agree with the guys above...high 500-low 600 lift and 238-246 ish sounds alright

If the intake duration and lobe was properly spec'd for the application an aftermarket headed LT1 will make similar peak hp, better driveability, and more low end tq with a smaller split then a wider one.
It may not necessarily be single pattern, but it doesn't need that huge split that the lazy old school grinds use.

A strong exhaust port will not need as long exh duration as a head with a weak exhaust port.
Possibly, but not definitely.

Hope you're not refering to a stock intake LT1...

"Old school huge splits" rule most professional drag racing classes

I agree with everything you responded - I am not saying small split cams are always the right choice, but definitely not saying never. There are just so many variables that it is extremely difficult to compare.
There is more to a car then its trap speed. I'll trade 5mph for 2 tenths any day of the week.
