Take it apart? Plan on what you want to do with it. 99% street with 1% strip? or more of a strip motor? How much hp do you want? Do some research on some proven combos and/or talk to some local engine builder guys. How much are you willing to spend?

I've got a 350 slowly gathering parts around it. Punched the numbers in for the cam and the other things into desktop dyno 2000 and it came up with 520 hp. Anywhere close to that would be ok with me LOL.

LG4 305 .030 over, performer intake, holley street avenger 670, xe 256 cam, tes headers, 3 inch single exhaust, spintech muffler, 14 x 3 inch drop base k&n.

 

first, rebuild iit stroked to 383, then stab in a blower cam and some monster valvesprings, strap on a weiand 10-71 and some carbs or a procharger and tpi setup, with some aluminum heads, at about 9:1 , youll be flyin

 

I would go with the Chevy Vortec heads. Ther're cheap, and perform well. I built my 350 with them, and it runs good. I don't know how strong it is yet because my trans crapped out when I put the engine in. Beaters suck!!! :P

 

how much did u pay 4 the vortex heads this will be a slow project due to cash flow im gonna build it piece by piece

Vortecs can't take much cam, and if you go to modifying them for it (springs, screw-in studs, etc.), you're starting to get into aftermarket performance replacement dollar range. Remember, Vortecs started out as truck engine heads.

Sportsman II's, Edelbrock or Holley aluminum would be money better spent.

Certainly, though, build the shortblock well enough to withstand future upgrades. Forged or hypereutectic pistons, good bearings and oil pump, have the rods checked & resized if necessary, etc.

evilcarman was right you need to decide what you want to do with the engine. How much hp how much torque? Power adder? How much money do you want(or have) to spend. All these are dicisions you need to make for your self. After you have made these decisions you can then ask on advice for specific hardware.

I EITHER GONNA PUT ON A BLOWER OR SUPERCHARGER IN TH FUTURE ILL PROBABLY SERIOUSLY RACE IT BUT I STILL WANT IT TO BE SOMEWHAT DEPENDABLE

With a blower in the future you will need to consider the tradeoff in compression. I would go for more cubes (383 or 396 kit) with dished pistons for iron heads, or flats for aluminum. This will put compression way to high for blower in the future.

A dedicated blower motor would have deep dished pistons with cr in the low 8's:1 which will barely satify you in the meantime n/a.

These's blowers for stock compression are pretty lame (pushing 6-9psi at 9:1) when if a dedicated high compression/proper cam motor will whooop them and save you the $3000 on the cost of them.

But a low compression motor with much more boost and power is possible. The ultimate tradeoff.
