find a gtp or regal gs or super charged bonnie at a junk yard, pull the heads and lim, blower, blalancer and extra pulleys off it. you also need headers to run a top swap. speed daddy headers are the cheapest, best header your gonna find.

or find a running used l67 and drop that in there. those are not so easy to find these days tho.

gaskets, fluids and bolts are about 200 to re assemble it. most of these engines leak oil, its either the rear cover or the pan. its worth it to re gasket the whole engine. what i did. bone dry now.

you'll need a tune for it, overkill is good with the 04 up cars. hes got that all figured out it seems. hes a vendor here. sells canned tunes.

my car cam with a supercharger and i blew it up, so im running a n/a block now, its a bottom swap in my case, but still a top swap in the end.

its stronger then a stock l67 for sure. add a ic and you can drop pulley size easy, cam will help too. and still keep you at or around 300 hp. with a cam and ic. trans wont hate you to much.

if you have e85 where you live, thats just free HP. lots of guys run that, then you can ditch the whole ic set up idea and still drop pulleys if you have corn. e85 you need larger injectors and bigger fuel pump and pump re wire. still cheaper then a ic set up.
