well guys i currently have a 350 sbc bored 30 over 2 bolt main block with hipereutectic flat top pistons, 10.3:1 compression ratio with 64cc...with stock 3.48 stroke, its going to an 84 chevy c10 short bed...truck has 3,73 gears, fully built th350 transmission (shift kit, blue clutch pack) etc... with a 2,500+ stall,
long tube headers, edelbrock 600cfm carb

parts i still need to buy:

more than likely i will go with a 383 stroker crank for the 350 for more torque...
i will also go with the performer rpm air gap intake, 1.5 roller rockers

going with vortec heads or racing head service 180cc heads...

My question is: What CAM would be best fit for my setup using the 2,500+ stall and all of the above... or any suggestions or modifications on my setup?

i want the 355 or if i make it 383 stroker to pull the heavy truck down the track 1/4 in like low 13's or high to mid 12's is my combo good enough to take me there??? or what do i need to change? what cam for my setup?

thanks in advance

There are over 100 dyno tests HERE , some w/heads similar to yours.

Choosing a cam is like choosing a guys date for him. :pain: Something better left to the individual, IMO- unless he's in a real bind.

What usually works is to choose a cam or two, show the specs for it (not just a part number) or a link to the cam card. Explain why you picked it, i.e. what are you trying for- top end HP, low end "grunt", mpg, a HP goal, whatever.

With that, we will gladly scoff at it, pick nits and generally run your **** into the ground. But in the end- you will have everything you need to make an informed choice.

example: i can use something like 2,500-6,500 rpm range cam???
Basically, yes. Maybe someone has a link to a good guide on choosing cams that isn't too rudimentary, that would help.

But what I've seen to be about the best bet, is to call the company of your choice, be it Comp, ISKY, or who ever you like, and talk in depth w/their techies.

Have as much info as you can muster and be realistic (no, "I want 500 HP, 25 mpg and a smooth idle!" type of requests) and they will 9 times out of 10 point you in the right direction.

Armed w/their recommendations, you can shop around for different manufacturers w/similar grinds.

BTW, I replaced the link above- it'll work.

so the cam i can choose can be almost any cam, it doest matter if its for a heavy vehicle???
The cam you choose is based on the engine size, vehicle weight, the compression, gear ratio, intended use, type of heads, and on and on.

I suggest you start by looking over a cam manufacturers catalog of cams. They will have the basic RPM range, usually the compression ratio and converter stall required or gear ratio, sometimes they will make a carb recommendation.

After you take a look at what's there, I suggest- again- that you contact the manufacturer's tech line and talk to them.

If you want the best cam then you cannot buy one of the shelf. It'll need to be tailored to suit the rest of your components. Even if every part of the engine is the same except your cylinder head's runner volume changes then you need a different cam to run best.

That being said you can probably just pick one out of a catalog that describes what you want and what you have and still end up with a pretty good running engine.

so what street and strip cam would be best for heavy vehicles using a 2,500+ stall? i just want for someone who has a heavy truck running strong to tell me or recommend me a good cam for my setup... anyone running good numbers on a heavy chevy truck what cam your using?

well i just finished talking to someone from summit racing and they recommended me the 279th7 grind cam that fits my stall range and for heavy vehicles...

cam is a comp cam 279th7... would this cam make good power and torque in a 383?

YOu need to decide on displacement 1st, then compression and cylinder heads, exhaust setup, and other misc. stuff. If I were you I'd go 383, some good heads (EQ, Dart, AFR< RHS, etc.) and about 9.5:1 compression. Build it for mx hp a little below 6,000 RPM so you have a stout tq curve you can use. After you get the rest of the info ask for a cam. otherwise its just a SWAG.

thats why i haven bought any stuff yet cuz i want to know what would work and what wont... am for sure going with a 383 with vortec heads and compression would be around 9.5:1- 10.1 and exhaust am going with y pipe 3 inch with muffler long tube headers...
