Dyno Guesses & Bench Racing Forum - Newbe sorry!! LQ9

Thanks guys i am hew to the ls engine. I just got myself a lq9 and a 4L60E trans at a great deal. my ? is how much hp does it make in stock form? And what is the deal with swaping out the cam to a ls6 can what all do i need to get to run it and how much more hp will i get by doing this? I and putting it in my 68 camaro`and using a standalone harrness?? Any help would be a great help. Thanks

If youre gonna go to all the trouble and expense of doing a cam upgrade there are much better choices than the ls6

^^^ exactly, these motor respond very well to a Cam & Spring swap.

Stock the Lq9 was rated at 345 HP at the crank. That would get you around 300 at the rear wheels. Add a Ls6 cam and you would get around 375-380 at the crank. Really not bad if you want to do it on the cheap with homologated parts from the OEM. As others have pointed out though there are after market choices that would get you much more power. A basic 224/224 .580/.580 114LSA cam would make 40hp more than an Ls6 cam. Also something to consider is are you going to carb the motor or use EFI?
