What would this combo lay down with a healthy cam?

Parts list: 408 short block forged internals Tf 220s hollow ls3 valves, ported/blended by Tooley. Pm guides
Dual springs Fast ported 90/90 with 42 lb injectors w upgraded fuel pump
Stock rockers with trunion upgrade Larger truck Delphi MAF
Custom healthy cam from EPS Under drive pulley
Morel link bar lifters (the good ones) Hardened pushrods measured to specs
1 3/4 long tubes
M6 ls7 clutch at the moment plan on upgrading in the future
Still debating on compression/ milling heads want to run on pump gas 93 octane Custom tune Ported oil pump

I know this setup isn't ideal due to the cast heads/ smaller headers and not running a 102 but ballpark? Open to suggestions this is just a street car not looking for crazy numbers.

So much help thanks lol... Anyone?

Wow! I really have no clue, but i'd say at minimum 500 whp for sure

Not sure on the HP, but it ought to make a ton of torque and be great fun on the street.

WS6ICK2k

Thanks I'm hoping for 500+. I'll be sure to let you know the results. Dark man yea I hope it's nasty on the low end that's kinda what I have been shooting for.

Also I feel like the heads will give me room to grow in the future if I ever have them CNCed to the 235 program.

Precisely my thought - the torque will come with the cubic inches, the real horsepower will come once you really feed the monkey.

You say healthy cam; just how healthy of a cam are you looking at? I think your choice of heads is great. With Tooley's hand work, those heads will be just as good, or possibly better, than TFS 215cc heads. Here is something Tooley had e-mailed me a while back when I was trying to decide on heads:

The only thing I would do to the LS1 heads out of the box is hand blend the CNC bowl blend into the intake and exhaust port short turns, and shape the exhaust port valve guide boss, don't touch the intake seat, not even with a sand roll, you will lose airflow. We have been shocked at how few head porters have worked on these heads, but they are not going to pick up huge cfm like on other as cast heads. Just a few hours of simple hand work is all that is needed to bring these heads up to TFS 215 power levels. Good luck!

This. Low end torque aught to be quite nice, but don't think the top end will be anything impressive for a 408. But if that's what you're looking for then it should be plenty.

I have a good friend that just went w/ the same Tooley touched up TF220 setup (Tooley finished, LS3's turned down, & powdered metal guides) w/ a tooley 231/241 cam, Fast 92, & a LS2 TB. It put down 460/425, and that was in a 347! Depending on your cam I'd say the extra cubes would be good for near 500 IMO. You never know what that day on the dyno holds, but that's just my guess.

We've had several 402-408 c.i. engines with As Cast 220cc cylinder heads and Fast intakes make 500rwhp and 500rwtq.

Everyone thinks bigger is better when it comes to cylinder heads and 75% of the time or more that just isn't true!

Yep! Compress it to on the edge of pump using your DCR calculations and let'er eat OP! Compression and cubes will soak up the cam overlap, making it a good cruiser while giving you extra Tq and HP!

Just a little secret learned from Martin@ tick

WS6ICK2k

Martin what kind of cam does this include? Might just have you spec me a custom one using some of the more valve train friendly lobes.

Also since you work with TEA now can I just get the heads mentioned above from you? Ls3 valves already touched up.

OP, how big are you wanting to go on cam? Ballpark specs please.

WS6ICK2k

Phoenix I honestly haven't decided at the moment. Thanks for the comments after a lot of research I feel like these heads are the way to go for future options down the road. I'm still looking into how the additional CI allows you to run a larger cam profile and still have good drive ability. When I was choosing a cam for the stock ls1 bottom end I ended up going middle of the road 230s similar to your cam the SNS torque max 2 but slightly larger. The only thing I have decided on for sure is that I want to run more reliable lobes such as the ones eps uses. I'm basically looking for a middle of the road option for a 408 as well.

Future goals would include eventually CNCing the TF 220s to 235s. Selling the fast 90/90 setup going with a 102 combo, as well as running a set of 1 7/8 headers. But since I have all these parts already it will keep me within my budget and hopefully make good numbers.

I would think something in the mid 240's intake and low 250's exhaust would get you great overall power and still be very streetable with a good tune.

The last one I did actually had what I consider a fairly large cam(243/250 113lsa) and it made 520/495 to the tires in a C5. 11.5:1 static CR and 8.6:1 ish dynamic IIRC.

I can most certainly have the heads ordered direct from TEA along with having the springs matched for whatever camshaft you decide to run.

If you favor a Cam Motion grind seeing you have a cam from EPS currently, I can also have Kip grind something for you to my specs as we're a dealer for CM now.

I'm sure whatever Geoff cut for you is a good camshaft though.

WS6ICK2k

You most certainly have my business I will be in touch. That's awesome your becoming a one stop shop working with TEA and kip now. Since I had such good luck with my EPS cam I think I would like to stay with the cam motion grind. I also would like to get your recommendations and spec the cam out for me.

I wasn't aware that this was an option but very glad to know now.
