If you're thinking to rev, look into fast with mid length runners

Ive seen Tooley TFS as cast 220s run 5.0s in the 1/8 mile..... also on more than one setup/car not sure what class they was in tho.
Also don't forget about Mark Koehler, Ohio
Firebird, 7.50@194 MPH
106mm turbo/KUP/ERL hydraulic 441/TFS 245 heads/Edelbrock intake/315 drag radials. According to my calculation thats 4s in the 1/8 mile.

Once they get the chassis set-up figured out on this car it will go bottom 4.70's all day long and 7.30's in the 1/4. Straightline won the 2014 and 2015 Xtreme Street championship with their red BBC nitrous car, they will have this car flying ET wise in a very short amount of time.

This car went 5.01 on it's FIRST pass ever that it didn't spin. I guarantee those set-ups you're referring to didn't go 150+ with a 76mm turbo weighing 3100 lbs. Do the HP math on the trap speed and race weight...

Along with being Hydraulic roller equipped... This 416 inch LSx block based engine is topped with a set of Trickflow 245's prepped by BTR. This car runs 4.5s @ 155 plus. Owner name Justin.... cant remember the last name.

This is so funny....Aftermarket heads vs Factory heads is basically what you all are getting at. I spoke with Mr C. Roddy and theirs nothing Avg about the car Except the number 427(also has a set of billet lunati rods and 4.130 pistons 14+ comp for $1k ). Converter would set you back $5k used that's from his mouth. And the guy's that are running these numbers wouldn't use anything stock. It's a good Budget head being Ls3's.
Do any aftermaket rectangular heads go as fast as any of the times listed? Fair is fair. As it's only $ we'er talking about. Was talking about crank scrappers was told is't not worth it I said there not that much was told neither is 0*weight oil and we are talking about the street with a BBC with a Procharger. It's all in the eye of the beholder for budget and how far one's Willing to go to go fast.

Yeah I started this thread comparing stock castings. Somehow it always ends up being max effort TFS headed big inch motors vs cooking cutter stock ls3 casting stuff.

I got LS3 heads on my car now with a Tooley cam ... they do great for the money. However I know they not the BEST cylinder head out....

Yea that's how it typically goes. What gets my huckleberry LOL is that once we say aftermarket we are now talking basically $3k for any decent pair of heads. Some like being able to say I have a name. Ls3 aren't the best but can do very well and on a budget. If you were to sayTFS 245' I'd say Small bore Ls7's so what then as the cost is Null and Void with $2500 as the beginning point and both still need massaging. Fair is only Fair. If your on a budget There is Nothing out there better.

One thing I won't forget from this thread: "Another reason why I highly dislike the GMPP CNC LS3/L92 heads. They are probably the poorest performing square port head I've ever worked with".

Bullshit. The title says it all along with your first post. Why do people "hate" on stock LS3 castings & that "they're superior to stock cathedral castings by far". That's not comparing. That's called talking(typing) ****. Your just a troll with a hurt vagina. Why don't you just get your car on a dyno, & to the track, so we can see how it does.

And you're comparing an engine with twin 76mm turbos versus a car with a single 76mm turbo. My single 76mm turbo customer went 153mph. He went 155mph with TWO 76mm turbos...

He took the motor out and is putting it back in his truck. I just did a solid roller cam for him. His name is Justin Kalwei.
