Default 725 N/A HP...for the street..what do you think

This is the MORE Performance 427 LS6/C5R race engine. They said it would be fine on the street, the valves would just need adjusting every now and then, if I went with a solid roller cam.

This engine with an F1 super charger and C5R heads would be the cats ***.

Do you think it would be OK on the street? And YES, I'm considering it if things work out business-wise in the next couple months.

Haha, I guess that your "legal issues" may be going your way. Congrats. I dunno. If I had that kind of $ to splurge, I think I would do a forged 402. Since your going to boost the hell out of it, i don't think you'll miss the extra inches. Probably save a lot of cash vs. the MORE motor as well. Haven't you heard of a rainy day fund? hehe

That engine's been around for a while. Remember, that's 725 fwhp, not rwhp. Probably a nice motor, just haven't heard of anybody owning one...just seen a picture of it in a magazine article by David Vizard a year ago. For that kind of money, you would hope it had C5R heads. Ported LS6 heads? For $28.9k?

C5R heads cost between $10,000 and $11,000, just for the heads. I already spoke with them in depth about it. They think they can get 700 RWHP with the use of the C5R heads.

That and another product that I'll be selling very soon that is going to be outrageous in North America. Getting the patent as we speak. I already have sole distributor rights from a manufacturer in China for their product.

Why a 402 and not a big cube motor? Stronger? Better reliability?
Maybe a 418?

that is an incorrect statement you can purchase the bare heads for 1200 each so more like 2400 for the heads.

Not according to Agostino and MORE.

They said they cost about $10,000 ready to install with all the machining. Ready to install is the only way they work, bare heads are mearly paper-weights.

why not just turbo charge the motor you have? You certainly don't have to worry about torque, and with a big enough turbo(s), i'm sure you could easily exceed 700hp.

"Estimated" HP is meaningless, and 700 RWHP NA is a fantasy. Low 600s at the wheels is a more realistic goal for a streetable engine that runs on pump gas, even with C5R heads.

If MORE told you it would be fine on the street then I believe you have your answer

I'll be trying something like this very soon with 93 octane. Was going the turbo route but I saw what Jason at thunder had for sale and I couldn't resist.

725 at the flywheel is a little over 600 RWHP the way it is right now, ON PUMP GAS. If you add C5R heads you can get approximately 80-90 hp MORE. That = about 700 RWHP N/A. Also, I never mentioned pump gas. When I spoke with them about this set-up I told them that I could use 104 octane all the time if need be as this car would be driven part time.

This is coming from MORE and other top shops, so I'm just telling you what they have said to me.

And remember when 500 RWHP N/A was a fantasy

What kind of power could be had if I turboed or SC'ed the motor I have now?

1000 RWHP?

__________________________

Here is a video of a forged stock displacement TT. 790 rwhp. With your motor with lower compression 900+ should be easily attainable. Plus a lot more streetable than a 700 rwhp n/a motor.

FYI. You should be closer to 1000 Crank HP with a setup like that.

My buddies down in Australia with T-Trims behind a 408 with ported ls1 heads are making 800+ RWHP. 1200RWHP on race gas with a bigger blower...

Talk to W2W and see what Kurt can offer you...

That's deffinatlly what I would do. Talk to someone else. MORE is so way overpriced that it's rediculous. A local buddy just had that engine package installed at MORE along with alot of other suspension/tranny mods. I believe they raked him over the coals for well over 80k and he says it still isn't right. I haven't even seen the car in 2 years if that tells you anything. I used to see him every weekend. They might build good motors, but I wouldn't pay there prices when we have great sponsors that sell the same for less. 28k is rediculous for what you get.....

Yeah no doubt. For that kind of loot I could buy a car making 800-900 horsepower and have enough left over for a nice trailer and a few steaks.

Depends entirely on the setup you go with, but if you had a shop fab you up a good TT kit, I am sure you could do 1000+ rwhp with 104 octane. It's all in the tune.
