What is your certain plan on rpm range you want, gearing your willing to use for sure and the stall speed. Not auto guy but to me less then 3000 stall would be waste of effort. As far as lunati advertisement on cam there is no such thing.

Fair enough. Can you explain why though?
I'm not looking to turn more than 6-6500. Its a fun street car not a track car. That being said id like it to be a REALLY fun street car. Switching to 3.55 or 3.73 in the future

I would not do a solid flat tappet today without taking advantage of the harder surface pro 55 cam core , i never had that luxury in my younger days. Crower 00305. 2700 to 6700 rpm in 350 cu. yours should drop 300 rpm on 383 cu. probably worse with the vortec heads. .050 240 int. 248 ex. Adv. 270 int. 278 ex. Lift int. .533 ex. .519 lsa 108. Int valve set .022 ex valve set .024. Cost not cheap with pro 55 cam core $247.00 at summit. Would do 3.70 rear and 3000 converter. Valve lift figures with factory 1.5 ratio. The int. Side 240 at .050 and 270 seat to seat tells you this is real quick rate cam should give real strong midrange power. Pro 55 cam cores are a different grade of iron then the cheaper cost cams.

Extreme comp and lunati vodoo both quick rate cams made off cheaper cam core. The comps extreme failures well known, but they dont care another sucker coming through the door any minute.they were worth a damn would never put a fast rate ramp on a standard cheap cam core.

Vortec head compaired to early stuff had considerably better combustion chambers and its airflow was better realisticly 220 airflow old heads more 190. If its ported right would be all the head needed for his obvious mid range rpm goals. With the change in cam the cork in airflow will become the performer intake manifold, should change that to performer rpm.

So I've been going every which way with this build and thought I'd make a dedicated cam choice thread to get a final recommendation from as many people as I could. I'm sticking to a flat tappet cam. I like the idea of a solid cam for nostalgia purposes and sound but will consider either solid or hydraulic.
Engine:
383 crank
64cc ported vortec heads stock valves
10-10.25:1 compression
Lift limit .550 on the heads
Long tube headers
Have Performer intake but can purchase another
Slayer 750 carb
Th400
I am planning on changing from the stock torque converter.
3.08 gears but am changing those in the future
Goals: Mean idle. Obviously as much power as streetable. Car will see track maybe once a year.
Lay em on me!

I had new 73 with 454 at 4000 miles pulled engine amoung lots of mods the cam went back in was 265 at .050 adv. 310/320 lift 560/580, lsa 108. Trans 2.20 low gear M21, rear end 3.36. Obvoiusly a freeway flyer. No problems with power brakes or vacuum headlights. That said all that vacuum stuff all new up to snuff. ordered the car with no A/C no power windows brakes and steering power. I considered the car a sports car not a drag car still do to this day, much better platforms for drag cars. When it was 18 months old pulled engine put all factory stuff back on engine and the exhaust manifolds. Sold it bought 66 vert had no power anything 4.11 original rear gears in it. Cam put in 73 crower solid flat tappet, did cranes and factory cams back then. 1 mistake i made 12.5 compression 331 build used chevy LT1 cam, not enough cam. Put it in 66 vette 4.11 rear. Pulled that engine did 396 bbc build for it. 69 to 79, 10 different cars 5 of them new cars 1 new pickup.

Shared a shop with a friend back then we would rag on one another. He had a lunati cam i called it a lunitic cam, he called my crane cam a crap cam. He had sbc camaro, i had the 66 BBC. He would say BBC weak as wet toilet paper. Lol bunch of us went to drive in theater he did not want to pay to get in, put him in trunk of 63 chevy impala got in then i would not let him out. Lol, out one night did not take him home just dropped in off at his work place next day. His job lifting cement blocks all day off conveyor line and stacking them, with no sleep. lol

If you want cheaper do the comp. 282s its ramp rate slower will last long term compaired to extreme series comp cams. Have fun whatever cam you decide on.

Ok a true mean idle. Price tag $145.00 at summit. Howards solid flat tappet 110812-06, summit part number HRS 110812-06. Power range 2500 to 6500. Adv. 276/280, .050 248/252, LSA 106. Lift 1.5 rocker .535/.540. Have no clue if howards makes there own cams or are made for them.if im thinking right vortec has small intake valve not a good thing when you go up in cu. 106 lsa will help that. They vortec head you have a 1.84 intake valve ? 283 chevy 100 cu. Smaller then yours had a 1.72 intake valve.
