^ definately. i thin kthey sell jdm longblocks for 1500. stroker motors, and rebuilt ones with cp pistons, only catch is you need to send the core to him to get it at those prices (cept for the jdm longblock)
ATS sells a forged shortblock for upwards of 2500 but no need for a core though
and chrisK's...well he can build whatever you want and would need.
What is your budget and what type of power are you looking for?
If you want 250-350 rwhp, consider a gen3 longblock swap.
If you want more than that, consider a built motor. I would put ATS high on that list.
If you don't want more than a decent usable longblock, search the sale forums. I have one I would sell, and there are many others there. You should be able to get one for less than $1k shipped.
Also telling your area would help us steer you toward a local shop, if one exists.
Josh at www.chicoraceworks.com has probably been the friendliest vendor to order from in my experience, he seems to be the most flexible. His pricing for a built longblock are about the same as ATS. But ultimately, I think the biggest factor will be who is closest to you. Also, IIRC, The ChicoRaceWorks longblocks come with all the pumps and everything already installed.
ATSRacing and Engine Logics are I believe both in Texas (E.L. in Houston I think, and ATS is in Denton), ChicoRaceworks is in Chico, California. Those are the major US builders that are active on the board that I know of off the top of my head.
But if you are just wanting a built longblock, then you cant go wrong with either ATS or CRW.
Im in san diego. I guess for now, I will stick with my stock motor and work up the turbo parts. If I ever blow this one though, you can bet CRW is top on my list. thanks guys, ill go update my profile now.
