Default what motor should i go with... Bang for the buck

Can a bunch of yall put your 2 cents in and let me know what i should build... I have been doing my research for a little while and can't determind what motor to go with...
LQ9, LQ4 or a LS2... or any other motor like that... I am planning on running like a 402 or 408 with forged internals and either boosting or adding nitrous to get around 600rwhp but still be streetable... I know thats a lot for a streetable car but with forced induction it should be easy considring it will be making a good bit of the power... any suggestions would be nice add if you have any of these motors for sale feel free to let me hear about them

iron block 402 with 317 heads will easily meet you goals,and be very cost effective-i generally sell a longblock like that for 5750.00

Shawn roughly what kind of #'s would that longblock putout in NA form behind a six speed?

Would a L92/L76 setup be anymore cost effective and/or perform at a higher level than ported 317's?

weve gotten over 500rwhp with ported ls6 heads and good intake and headers.The l92 heads are def a better deal,but they do require some work to make them work well.the cost is about the same,but they will make more power.

the low compression fi motor will not make that great of power n/a possible 400 or so,and it comes with no intake,oil pan,valve covers-its a longblock,the ls2 longblock i do supply with frt rear and valley covers.an ls6 intake will work fine for a fi application
