I haven't bought anything yet, but I've been planning on running this setup, and I need help finding a cam that gives me good horsepower but doesn't suck up all my gas...

Here's what I've got planned so far...

350 block bored 30 over
Compression 10:1
crank scat steel 3.75 inch
Rods scat 5.7 inch H-beam
Pistons/rings federal mogul forged, 1/16 inch rings
Oil pump Melling standard pump
Oil Pan milodon 5 qt.
rocker arms Roller 1.5:1
Cylinder Heads 220cc runner size, chamber size 72 cc
Valve sizes 2.08/1.60 inch
Intake Edelbrock pro-flo EFI single plane
carburetor 1000 cfm throttlebody 36 lb injectors
ignition MSD-6a
Headers 1 3/4


Any camshaft suggestions? I'm Aiming for 400 hp

 

Engine or wheel Hp? Big difference

Why such BIG heads for a low Hp street 383?
Most run 195's

Also current thinking is to have as small as possible chamber (< 64cc ); makes for better combustion and spark propagation

 

Engine horsepower....

I guess I kinda thought those heads would be good, but ill go with 195's...

 

What year is the block?

Are the heads aluminum or iron?

 

Its a 350 sbc 1996-2000 block from summit racing, already bored out 30. over.


The heads are iron. I don't think putting aluminum heads on an iron block is a good idea. Just my opinion.

 

why not??
also, i agree with the 195 and 64 cc quote.
but im biased, thats what im running on my set up. My compression is in the 10.8:1 range though.

im running comp cams 288 xtreme energy cam.
try out their camquest

TrickFlow Heads 195's, 64cc Chamber 2.02/1.6 Valves
1.6 Rockers, Full Roller
Comp Cams XE284H RPM range 2300 to 6500.
240/246 Duration @ .050 .507/510 Lift w/ 110 LSA


this is what i am using the lift is figured with the 1.6 roller rockers

 

Because aluminum expands quicker than iron. I'm not saying its a bad idea, as aluminum heads are great, but I just personally wouldn't mix.

 

Your opinion has been disproven for over 50 years and millions of engines and miles.

 

Lol, jerk.

I still don't like the thought of mismatching. /rant.
