I just wanted to know how realistic the 400-500 horsepower range would be to achieve from the following set-up:
Chevy 350 (80-90's model)
bored out 60
new Sealed Power crank kit with bearings
new 60 over Pistons
Vortec heads
Melling MTC-1 Cam with lifters
Rochester carburetor (with huge secondary jets)
stock exhaust manifolds right now, but i'm looking for some headers

I would greatly appreciate any tips, tricks, or cheap upgrades that will get me into that range or beyond it for sure, thanks!

P.S.-I was watching a car show on TV one day, I don't remember exactly which one, but it was about some kind of ignition/distributor upgrade that plugs into the distrubtor somehow, if anybody knows about this product, could you tell me what exactly it is, how much it would help out? thanls!

Lone-Shark,,,
Getting one horse per cube takes a few tricks of the trade.
If,,, you brought cubic knowledge to the table, we may be able to point you in the right direction,,, to achieve these lofty power expectations.
$6000 to $8000 should get you there
Sorry, didn't mean to scare you off.
Seriously tho,,, there is no cheap way to make power,,, unless you can do most of everything yourself. and then it isn't cheap either.

Hi there,
 Suggest that 425hp is good effort for 355" and remain streetable without bone
 shaking traumas. Should be achievable under 6200rpm. Take good advice and go
 slow with the process..All the best..Skyeking Laugh

It depends on your pocketbook. 4-500 is surely achievable and you can buy crate motors that will get you there.
What are you looking for, street, street/strip, strip?
There is no doubt a SB can be made to make big HP numbers, but the cost will skyrocket as the HP numbers go up.

+1

L-S,,,
Summit has a 350 crate engine by Edelbrock, 435 horse 435 ft/lbs torque EDL-45901
$6999.95 comes with 800CFM Thunder carb,,,
I'm sure there are many others that sell crates
but none are cheap,,, costs money to go fast
unfortunately

its really not all that hard if you get some work done on the vortecs like some 2.20 1.60s and a nice porting job and springs. and a nice compression of like 10.5:1 how ever you want to do it.   and a nice lower duration cam with a high lift like .550, and good intake like a rpm air gap or victor jr if running alot of time upstairs. good 750carb, and good set of headers. with all that 450-500hp is what i would say.

i dont know the specs of your cam sorry. have you thought about stroking it?
i wouldnt go .060 over if i didnt have to.

You know,,,
to make 400 or 500 horse power would be a lot easier with a big block,,,
dollar per dollar and there would be room to grow for more power, yet.
just a thought

papa,,,
"budget" means different things to those with money and then those without.
I don't think I would consider a 500 horse power build with $500 dollars in my pocket,,,
like most folks only have
One horse per cube is realistic,,, anything more is a bonus and takes savvy and money,,,
without the do it yourself savvy,,, even more money
such is life

It's all going to depend on the compression. Run 10.5 or 11:1 compression, getting over 400 HP will be easy with a .060" over 350. YOu'll just need forged pistons and a hot ignition to prevent detonation, and have to run 93 octane all the time.
