I posted my 1974 620 for sale and don't want to sell her. I have an sr20det in the garage that i want to put in it and keep her. Does anyone know anyone that can do the work or even talk me through it. Please. I know it sounds lame but I'm kinda stuck with time. I gotta move and posted all my rides for sale

Sounds like your in a ruff spot... not on the right coast to come help you, sorry.
So you say your selling all you rides, are you trying to keep the 620?
Is there no motor in the truck, does it need the swap completed to drive?
What's your time line like?
maybe alittle more info might help, current condition of the truck a pic or 2...
Ca should have a bunch of resources to help you...

Rent a storage space from someone with a garage. Tarp it up and come back to it when you have the time. You can't rush these things it takes months to do it right. Having someone do it right and right away is $10,000. Having somebody's cousin Earl do it for $1,500 gets you shitty welds, even shittier red neck engineering shortcuts and stuff stolen..

I've seen a number of ads on Los Angeles craigslist from people/shops? doing SR20DET installs into various vehicles. Their pics show a 510 and a 620. I don't know the cost. I haven't seen the ad in a while, but I haven't looked since I bought my SR20 motor. I haven't done my swap yet, but expect to soon. 

 

Though having said that, if you're not mechanically inclined, or don't have a best friend who is, it's not an easy job. Neither is it cheap. You will spend far more than you expect just to get it in there and running properly. It will likely take you at least three times longer than you think (expect at least a few weeks if not months of constant progress in evenings and weekends. Guys who can do it more quickly will cost you for their knowledge, or you'll get a hack job as Datzenmike said. There's a reason why there are so many unfinished 620s with SR20 engines for sale.  

 

I'm not trying to scare you, but your questions and lack of research implies that you don't have a clue what you're getting into. 

 

There have been a number of threads on various forums with some general directions. None of these are complete or detailed, but you can get the gist. Search google.
