99 Black Bird T/A: I see you like the Ls3 TFS heads, nice but not that good all together. As is I believe or rather I know the TFS 235 or 245 would make a better choice if you were to find a cheap pair of stock casting for around 300 bucks then I would say Yes on a Ls3 casting and have them Cnc'ed. If your going with a Rectangular port get PRC small bore Ls7 heads or Mast Medium bore heads as it's not just about the 12 deg. valve angle. Raised Runner is the the key and Ls3 based heads have a Low runner to start with. Glad to see everyone happy with the clutch. BTW call KIP and ask about how well the Low Lash roller cam is on parts. 600rwhp out the back door with ease. Also Comp Cams makes adjustable stud mounted rocker arms for around $550 to work with a solid roller. 600 rwhp lies right before you and as basic as it gets. Call Kip for details on how long he's run his LLSR. It has been a while and still no spring change give him a call.With this setup your not @ $2200 nor $2500 to run a solid roller. Trying to convert 1 person @ a time to SR cams.

I love Tony's work and know for a fact he's the man. Just ask how much those heads cost? 4k for Ls7 heads.
Funny.

Actually real world comparison and finding out how much horsepower a car actually have is at the TRACK! MPH my friend.

Black Bird- If you really stuck on those LS3 TFS heads its some in the classifieds for trade. The guy wanting to trade for a 225-245 aftermarket cathedral head.
Makes me wonder tho why do he want to trade instead of selling them....

@99Black - I totally understand. All I can do is keep people posted. I'm over 10k miles so far. But it's not 100k.

Edit - at least acknowledge there's a difference between "it won't last on the street" vs "haven't seen evidence yet because the LLSR is still new"

@Jake - Frankenstein makes great ****

Nothing funny about it. I've got a set coming right now, along with ported MSD, lifters, rockers, etc. my camshaft came Saturday.
I'm going LLSR. $4k is about a third of what I'm paying Tony for the entire top end.
My intent of the link was to shed light into the DRIVEABILITY of this package. I'm not looking to just punch a big number. I want a combo that will punch a big number, AND be driveable.

12k for the top end? You serious, Clark?

I knew youd like the rxt. Ive never been let down by it in nearly any application ls or ford.

It's actually $11 and some change...but there's also an oil pump, some ARP stuff, a balancer, a deck bridge tool, and a few little small odds and ends. I have under $5k in my RED 434" short block, because I did it myself. All in all, I'll be at $17ish for an engine that would cost $25k.
I used to race NASCAR asphalt late models. I'd throw $32k at a dry sump engine back in the day and not think twice. Actually bought several of those guys...
Nobody ever said this game is cheap. It can be done cheaply, but horsepower is a drug. You ALWAYS want more, and more is $$$$. I've been down the "punch a big number on a dyno" road, and it's a dead end. You end up with a vehicle that just sucks to drive...but I'm 45 years old. I prolly liked it when I was 25.
Sorry for the thread hijack OP!!

11k for a TFS Ls7 top end WOW!!!!!!! I'm speechless. You could have a custom LSR for that price with a 265cc runner.

The ls7 trick flows are $2750 (summit) but we have for $2700 even so obviously he has alot more into them than just what the heads cost. A custom setup on a set of heads can range from $750 for just a cnc job to over 2k for extra attention to detail, ti valves, etc etc. Arp studs alone are ~$300 for the pro2000 so thats 3k right there just in retail cost of 3 parts. He did say it was alot more than just 11k in heads and intake.

Yeah, I'll have more money in my lifters and rockers alone, than most put into heads. I certainly did not call Tony to save money. I called tony because I wanted quality, and driveability, along with big power.
If I wanted to save money, I'd have bought a supercharger...

Yeah Tony puts a lot of effort into the castings, starting with a custom CNC program, and then hand finished. Add in lightweight valves, along with springs set up for a solid roller, and the costs go up very quick. His stuff isn't for the faint of heart, or a low budget type build.
I recently picked up a set of Katech billet main caps from you guys for this build!

tech@WS6store

iTrader: (2)

Hell yeah! Thanks.

You dont have to pay alot for good quality, but for the best youve gotta forget the word budget.

Amen! Preach it brother!

Price, performance, dependable / driveable. Pick the two that matter most and sacrifice the third

I thought I did that

It's possible a LLSR might go 100,000 miles with correct part selection.
I haven't seen the street be kind to SR set ups in the past.
Those were SBC & BBC from ~ ten years ago.

The Isky Red Line Solid Roller Lifter was the other lifter I considered but it's more $$$$ than the Black Mamba's. I do like the oiling design.


I will consider a LLSR LS2 364 or 403 for my black 91 RS Convertible, later after the 99TA is completed. The convertible averages less than 3,000 miles a year and is never used as a daily driver.

For 11 grand i hope you get shaft mounted rocker arms such as T&D or Jesel with titanium valves ?

More choices....There is a rumor that Hawk's Motorsports is working with another company to develop their own LS heads. Depending on the derails and time line I may have another option to consider. Hawke has a great track record of developing and helping get to market innovative products for 3rd Gen fbody.

I still have some homework to do.

Reher-Morrison was outstanding when I talked with them about heads. Darrin Morgan took the time to go over the details of my project. Likewise, the WS6 Store was just as outstanding. I'm sure I will be ordering more parts for my project from WS6 Store. If they were a little closer I'd just take the TA to the WS6 Store. These are the only two vendors I've talked with so far that went into very detailed specifics to my build when I contacted them. Both earned my praise and respect.
