Lq4 build Hi all, I’m planning on building an lq4 for my 70 Chevelle. The motor is going to be NA at least for a good portion of its life and I want to make a good amount of horsepower (500+). Would I be better off stroking the motor or leaving it and just cleaning it up a little? Which route is cheaper and more durable? Any tips and advice would be much appreciated
What kind of budget do you have? I feel that a stroker is a great way to go, as long as your not planning 8k rpm blasts.
Are you planning to go EFI, or carb?
500 hp at the crank is relatively easy with 6liter setup.
Where are you located?

I haven’t really decided on a budget yet lol, I’m planning to go carb but I’m open to efi if it means I can meat my goals with les money put into the project. 500 at the crank is roughly what at the wheels? And I’m in Nova Scotia Canada
Unless you’ve got an open checkbook, id figure up a budget before you start the process. I’ve seen many, many guys start an ambitious build, only to get in over there head financially, and end up giving the project away for pennies on the dollar.
Try to find a pullout engine with the harness intact, ECM, etc, and you’ll be money ahead. You can put the fuel system together for a few hundred more, depending on if you want pump in tank, or in-line.

You’ll save a little coin going carb, just on the fuel system, but man is efi nice to have for reliability and tuning. 500 crank is low 400’s with a manual trans, and depending on the particular automatic, 375-400.

I will say though that budget isn’t a huge priority as I have a running motor in the car that works well so I’m not in a big rush to build this motor, if it’s going to cost a lot to get what I want I’ll just buy the parts as the funds are available

Youre really going to need a 408 for that and a good set of heads for 500rwhp.
I would recommend the tsp 237cc cathedral or 260cc ls3 heads, a nice 408 flat top setup and a good sized cam and youll be in the 500rwhp easily. it will take alot more effort to make 500 on a 6.0 but nearly the same amount of money really.

Misread the thread. OP went from 6.0 to a stroker build. I say TFS 235s. They made my boy car run low 10s at 133 with slouchy 60ft. Also made 550 on a mustang dyno at the rear wheels on a 402 LS2 motor.
