So did you decide on vortecs or going another route. If you go vortec your best bet is to get them new for less than 700 assembled pair. Buying used ones could be a crapshoot, may end up putting that much into them if they need rebuilt. Goodluck and I hope you enjoy your project.
I built a 355 for a guy 3 yrs ago that consisted of a GM block .030 over, stock crank, 5.7" rods, flattop pistons.
Then threw on a set of vortec heads from Scoggin Dickeys set up and already machined for more lift with .600 lift springs. I also used a Comp Cams XR276HR hydraulic roller shaft with a set of 1.6 roller rockers, and Edelbrock RPM AirGap with a 750 Holley Vac Secondary carb. The idle was noticable to slightly choppy and with a set of 1 3/4" headers made around 420 hp and 415-420 torque on the dyno if I remember right. It was a great little street performer with a 2500 converter, 2004R trans 4.10 gears in a '80 Malibu. Best of all I think he spent around $3000-$3500 for the engine build including the block machining. So it can easily be done on a small budget and be very streetable. Good luck and have fun on your build.

Re: building small block Update!!
Just got back from the junkyard and bought some good vortec heads for only 150 bucks!! Came off a good running 350 96 vortec with only 89xxx miles on it.
Just ordered the beehive springs, voodoo cam,and comp beehives with the 600 bills i was saving for the gm performance votecs.

Professional Products intakes are imported knock offs. Their finish isnt as nice as edelbrocks. However they do perform well. Way cheaper to boot. Search around on google, i believe one of the big magazines did a dyno test comparing them to their edelbrock counterparts.
don't under carb your car lol I'd go with a 750 double pumper with four corner idle, that carb is amazing and its not that expensive on jegs.comlilmagik said:
