Factory GM LT4 camshaft(not the LT4 HOT cam):
203/210 @ .050
.476"/.480"
115 LSA
Roller
idle - 4500 RPM camshaft
Going in my TBI 383. Not built yet so no statement about it. Should be a torque monster with 10:1 compression, such little overlap, roller and the duration of course.

what cam are you running in your engine that you posted the dyno specs on?
In my tpi 350, i put in a "350 horse cam" hydraulic flat tappet.
212/222 Duration @ .050 .435"/.460" lift 112 LSA.
My 469 BBC for my street/strip camaro i'm going from a hydraulic roller 238/248 duration @ .050, .578"/.608" lift 108 LSA
to a bigger solid roller cam..
260/260 Duration @ .050 .587"/.587" lift 108 LSA

here is what i run in my 355 (10:1)
duration:
.222/.222
Lift:
.447/.447
Crane cams hydralic lifter replacement for the L-79 (327CID/350 hp) cam.
same cam that came in the 350 hp 327's in the old corvettes but its hyd lifter and the grind is a little different.
Real nice lopey muscle car idle.

214*° 214° Wrong cam with 4:10 and 31's.
The torque is too high up in the revs.
I have 4:88's going in with 32" tires. Maybe 33's.
This cam should work better now.
If not I will have to install a stall converter.
I am also running an over drive transmission.
This may allow me to run the Edelbrock 204° 214° cam.
I like the idea of big torque at low revs.

230/236 duration at .050", 274/286 duration advertised, .490/.490" lift on a 110 degree lobe separation angle.
350 cid engines enjoy 108 degree lsa's but most cam makers are grinding 110's
unless you wanna fool with a circle track cam for maximum torque.
Cylinder heads and compression ratio dictate cam choice but a dual-pattern cam is always preferred unless you're running AFR heads which have a great exhaust port and will over-scavenge the chamber unless a single-pattern cam is installed.
do your research and make the right choice the first time.
here is a link to my web page detailing the entire build of a 440hp SBC in my '79 short-bed 4x4
