Agree, with the above, budget usually=s more used parts than new. not everyone wants that and that is fine. just changes the price parameter.
I glued together a pretty stought 455 based combo with used parts for my GTO over the last 2 years.
used 455 short block $500 a facebook score of all things
used lifter bore brace, just in case i get stupid on the cam later on $50
new race tech pistons scat rods bearings rings etc roughly $1300
machine shop bill was i think $1500 for bore, balance, clean, cam bearings etc
used set of 330 eheads and victor, morel roller lifters,dyno time only $3200ish
new head bolts $85
used ATI balancer $150
new flex palte $85
used hs 1.5 rockers $150?
nice used roller cam .400 lobeish $175
used carb and fuel pump$550 but i sold fuel pump that came with it for $125
new timing chain, push rods, gaskets, spotts valley pan, misc extras $400
already had oil pan and wires, distributor bought poly gear off here for $125
used moroso vacuum pump $300? mostly to stop any leaks

i get about 8k, now i wished i had not added it up! but it should be pretty bullet proof at less than 6500. I wan to run the local 10.50 heads up class and it will do that with ease in all weather as it is. I had headers and the car already.
went 10.50 first time out foot braking and 10.39 second timeout on the transbrake in 3500# car, with horrible 60 footers. converter is left over from the 540 that is now in the firebirdvand is way too loose. for this little motor. I think it will run in the low 1020s or better with new converter.

How much would this cost from a shop? I have no idea.
