New Engine for my C5 !!!

--------------------------------------------------------------------------------

I am having a New Engine built for my C5.

My goal is 525-550 RWHP with 450-480 RWTQ.

Naturally Aspirated !

The car is mainly used for HPDE Road Courses & Midnight Rides to Coney Island !

Where do I start??

The car currently has Stock 3.42 gears with Hardened Shafts.
Upgrade Spec Clutch with less then 10k miles on it.
Vortex Ram CAI.
GHL Exhaust.


I think an LS3 Block is going to be the starting point.

-LS3 Block
-American Racing Headers 2"(probably).

I know there are alot of Engine Builders on here. Please chime in with advice!

 

Give Mike @ Rapid Motorsports a call. He will get you in the right direction. I think one of his customers has a C5 that he road races all the time. It is 427 powered if I am not mistaken though.

 

LME 427 or 440 with some LS7 heads..

Just search youtube for LMR, you'll see plenty. What's your budget?

 

Budget hasnt been established yet.
Was hoping to keep it under 15k, including the install.

 

Call Texas-speed with that budget you can get complete 408ci Long block over 530rwhp + Nitrous and go over 700rwhp/

 

nitrous would probably be useless on road courses,

 

Nitrous is not an option. Its of no use as stated above for the Road Course, and I will probably only Drag Race the car once to get a Baseline.

Thanks for the ideas, keep them rolling.

 

15k including install and tune so take out 2k that leaves 13k for bottom and top end....call vengeance racing

 

What do you mean by Bottom and Top End??? Are you referring to Forging?
Or do you mean the "install" should cost 2k and the rest is for the engine???

 

RedVette24 shoot me an email at Ron@VengeanceRD.com... Ill be more than happy to put together an itemized quote. We can work with your budget and exceed your goals with ease!!

 

That sentence reminds me of days of thunder when harry is talking to Cole about the car being loose and tight and adding some wedge here and blah blah. Cole says " I'm an idiot when it comes to cars, They just put me in the car and said drive and I could drive" Not talking any crap here, But maybe poking some fun

 

Poke all the fun you like. But that is pretty much the same situation.
I can drive my car, I just cant diagnose any problems. Aside from the current HOLE in the Engine Block. That was pretty easy to figure out. Along with the lack of Oil and Anti-Freeze left in the motor.

 

550 rwhp is attainable with that budget. You could do a nice forged ls3 427 long block with oliver rods for around 11k.

 

Or just buy a crate LS7 theres an idea.

 

If you are going to track the car you can build a engine with more performance and much better duribility than a LS7 crate engine for the same kind of $$$...a stock LS7 will have a short life span as a track engine .... plus the LS7 does not meet his stated performance goals of 550/480. Call Vengeance they can exceed your goals and meet your budget.

 

He could do a 438 4.125 bore with a 4.1 stroke prolly reasonable with LS7 heads ?

 

Check out my sig....I can get you taken care of for just about any budget....

 

I would look closely at the TFS heads vs. LS7 heads. They make gobs more torque down low.

If I were to do it all over again I'd do a 427 or 440ci with TFS 225/235's FAST92/92. Much cheaper than a real LS7. My ported LS7 heads alone were over $4K. Over $1K for titanium intake valves.

LS3 block with 4" stroke crank= 416ci
LS3 block with 4.1" stroke = 427ci
LS7 block with 4" stroke= 427ci
LS7 block with 4.1" stroke= 440ci

You could have a 550-575rwhp/530-550rwtq setup that sips 91/93 octane and has great driveability and major kahones for your budget.

1 7/8" headers should be plenty BTW.

Shortblock= block/crank/rods/pistons
Longblock= shortblock + heads

 

There also a Trick flow 245 head very nice
