As the title asks...Would you do your Ls swap again? I am ALMOST..at the crossroads of bringing MY 81 BIRD back to life. I have a few very difficult decisions I must make before planning my route. Currently PONCHO 400 is DEAD. I borescoped #1 hole to find cracked block , busted head, busted piston after it ingested SOMETHING. (was not a valve??) SO Given the need for an entire powerplant I am almost considering a LS swap BUT I am NOT sure on the hidden costs or the results as i have not followed any LS stuff... (it aint PONTIAC). I do know that to achieve MY performance goals with the parts I have (already fuel injected, headers, blocks, cranks, universal tranny) I expect about $6000 worth of build to get me at 475 ish HP driving down the street. Can I do that with a LS swap?
