LS1 Vs LQ9 Procharged

Plan for build is around 600 rwhp. Would I be better off forging the ls1 or starting from scratch with a LQ4/9? Balling on a budget but still want reliability.

How important is weight to you? If you are after "only" 600whp I'd say forged rods and pistons on the LS1. Stock crank.

At that power level either one is totally fine

At that level, you can run a LS1 or LQ9 in stock form and be fine.

Save weight and keep the aluminum block.

I really don't see the point. There are countless non-forged LS1's out there running Procharged setups making far more than 600 hp and living just fine. As long as you have a good tune, you'll be fine. And if it does let go, you can always forge it then.

Yup, I've seen way too many blow up around here to care, and that's WITH arguably the best tuners in the nation. You can control some things, fuel quality and other factors you cannot.

Yea...If your running E85.

600rwhp and 93 octane is a time bomb just waiting to go off.

If your running 93 octane, a forged 347 is what Id do.
Id keep the compression 10.1, to keep the throttle response nice and crisp.
Low compression with forced induction makes for a slugglish ride in the low RPMs. Been there done that, Not fun!

The extra cubes of the LQ9 is offset by the extra 80lbs of weight. Again, Been there, done that.
