would like 2make 350 base engine more powerfull
69 DIRTY RAT:
yeah for about 5000 you will only get bits and pieces,which wont add up to kick in the pants horsepower! Thats why I say - keep this engine! if you want original! dont mess with it too much, The only thing you can do if you want extra hp is make changes internally! which will still cost more than $5000 to do properly.
Dont go the cheap way,there are people who will do it cheap BUT you pay for what you get!
Again this is why I come back to crate engines,they come with warrenties!!!!! you get big bang for your buck and you keep your oringinal engine how its suppose to be!! instead of paying for bits and pieces with little gain, save a little extra and get a decent engine. In most cases you cant have ORIGINAL and WORKED in the same sentence!

ZZ383 Crate Engine 425HP 12498772 Description
With GM's legendary Fast Burn cylinder heads and 383 cubic inches, the ZZ383/425 delivers incredible torque with smooth, linear delivery.
If your're looking for a small-block package that delivers big-block power, then you've found it.
425 horsepower at in incredibly low 5400 RPM, and 460 ft.lbs of torque at 4500 RPM make this the ideal hot street engine.
The excellent air handling and combustion characteristics of the Fast Burn cylinder heads combined with the ZZ383/425's 3.800" stroke, make this engine the benchmark against which all other 383 inch small-blocks should be measured. And its tough, too.
The 4340 nitrided and induction hardened crank and unique forged PM rods see to that.
The 9.1 to 1 compression ratio ensures that the ZZ383/425 is 92 octane pump gas friendly.
The ZZ383/425 gets a stout .509/.528 lift steel camshaft with 222/230 duration at .050 lift. Hydraulic roller lifters and GM's time tested 1.5 to 1 roller rocker arms round ou the valve train.
And, of course, it has the Fast Burn head's lightweight stainless steel valves and retainers for reliable performance at extended RPM.
GM's testing was completed using a GM single plane intake, P/N 12496822 and a 750 CFM Demon carburetor with mechanical secondaries.
Test header specs are: 1 3/4" primairies,33 inches long with a 4-inch collectors.
GM dual plane intake P/N 12366573 may be used for hood clearance on the ZZ383/425, but it results in a decrease in peak horsepower of approximately 15-20 horsepower.

Also note that you still need to buy your extractors, intake, carb and dizzy on top of that engine purchase figure.
Also as a side not is it just me that finds it interesting that the test motor used here used 4" collectors to get it's power figures?
69 DIRTY RAT:
1 3/4 prim. 4 inch collector they are the measurements for Small Block Hooker sidepipes - engine to exit! So theyre not that abnormally big! I think it does come with manifold,carby,dizzy! I just didnt put on the thread!Some of the other packages are complete turnkey also!

Ouch! I'm new to sidepipes but with the horspeower that motor is putting out it really doesn't need anything bigger than a 3" collector based on the maths behind things. Just an observation, I'm sure those guys have a better idea of what they are doing than I do.
