A little before-and-after dyno action on the Malibu. 👀
Stock 243 heads vs Brian Tooley Racing canted-valve heads
Before: 379 whp
Now: 401 whp
The peak number is nice, but the real gain is upstairs. The new heads are carrying 30–50 more horsepower through the upper RPM range instead of laying over.
And this thing is still about as budget as it gets 😂
250,000-mile stock LQ4 bottom end
BTR Stage 3 cam
Unported Chinese intake
650 carb
It’s already been 6.90s with the old 243-head combination. We haven’t even optimized the top end yet, so I can’t wait to see what it does with the right intake and carb on it.
There’s definitely more left in this old junkyard 6.0. 😎
