I have a camaro RS 305 LO3 with 700r4 trans and I want to do a swap and put a 5.7 engine in my car... but I have a big problem I have the 5.7 engine but is another junk ... The 5.7 engine it's an L65 with 4 speed manual ..... According to what I found The L65 have 145 horsepower 250 Lbt And my LO3 have 170 horsepower 255 Lbt I have 2 dogs.... If I do the swap I cant perfomance de engine L65 put imca heads with big valves , 280 roller cam , headers and a 600 holley carb.. And make more horsepower... but I need to know if it's a good idea or better I modify the lo3.....
