Common verbiage in the aftermarket intake world is “maximum airflow” but is it really maximum airflow without a Freakshow or F-Ø intake?😝🔥

Rest assured, we're not just a bunch of folks with a toolbox and a trucker hat, exclusively tinkering with modern domestic V8 cylinder heads. We're like a pit crew for the fancy crowd, pampering exotics and imports like Lamborghini, McLaren, BMW, and even giving these Gen3 Viper heads a spa day. Is what you're looking for not on our website? Just give us a call or shoot us an email!

Is this the most powerful LS Head on the market?

A couple of F Series fun facts!

1. In a 350 cubic inch LS(4.185 Bore, 3.185 Stroke), These F-710s made 932hp @9,240rpm. 2.66hp/c.i. Naturally Aspirated

2. Our solid roller 427 made 947hp with these heads at only 12.9:1 compression.

3. These exact heads still hold the hydraulic roller LS horsepower record in Will Tetros Nova making over 2700hp TO THE WHEEL.

A lot of people always wonder why the F-Series has a premium price tag. The results time and time again show why. They're also designed, cast and machined right here in the USA! Offered in LS1, 3 and 7 ports.

When we did our 5 head cylinder head test, PRW reached out and asked if we would stress test their new LS Head Bolts as well! We’re always down to try new product!

These things did not disappoint! We made over 1000hp for over 35 dyno pulls and the bolts didn’t skip a beat! REUSING THE SAME SET! We were so impressed we decided to toss them on our website! Check them out at frankensteined.net

If you aren't buying the Torq-R porting program for your street LS3 what are you even doing?!? $1,852 OUT THE DOOR. This is the absolute CHEAPEST way to get into FED heads and they perform GREAT!
With focus of making power in the mid range it makes these honestly one of the best options for the guys driving around looking for some more fun. Even suitable for the road course /AutoX guys that could really benefit from the most power in that 3000-5000rpm range.
