LQ4 or LQ9 Hello everyone,
I'm still waiting for my first post to show up but in the meantime. I'm trying to decide an engine for my 72 Nova and wanted to see what the difference is between the 2 other than power and compression ratio. Found this post LSx Engine Identification and at the bottom of the starting post it states this:
Would that hold true for the LQ9?
Is one better than the other?
Are they both good to use with a turbo?
Appreciate any responses

Custom Cubes:
If you are fortunate enough to get your hands on an LQ4 6.0L engine block, you can bore it .030-over and purchase a 4.250 Lunati stroker crankshaft to produce a 434ci. GenIII engine.
Add a set of GM Performance Parts ZO6 cyclinder heads (PN 12560801) or have the stock LS1 heads ported and you've got yourself a serious engine.

Thanks for the reply Joe
So basically minor differences which won't make a difference if the engine gets rebuilt. I'm going to run stock for now until I can get the funds to do a rebuild and beef it up for forced induction years from now

Yeah, I'm gonna have to wait since funds are limited and have quite a bit to do the car, its just a shell at this point. So trying to keep initial costs to a minimum and eventually over time get other things done

JoeNova is right Jcasty.... a stock LQ4 with a 200.00 cam can make plenty of power forced induction
I have 2 Nova turbo build threads if you want to check them out in the forced induction section to get some ideas... built a 72 5.3 turbo and now doing a 69 6.0 turbo
