MVP'S ZO6

ok so I have been thinking about this for quite some time now. I was just going to sell my vette and buy a built C6z but I figured I'd have more fun building my C5 and I want to do it. I want to build a 454 LSx engine and slap a centrifigual supercharger on it. here's what I'm thinking? any comments, suggestions are appreciated. (BE NICE! LOL)

Vehicle: 1997 Targa Top Vette

Engine: Warhawk block, LS7 heads
Custom pistons to achieve a 10.0:1 static compression ratio
custom spec cam for my application (after I do all the math homework)
Oliver rods
Lunati Crank
Everthing buttoned down with ARP fasteners
Fast 102MM intake manifold
14# of boost for the street.

I want to be able to make 4 diget numbers in show off mode. i.e. more then 14 lbs of boost. However, realisticly I'd like to make 800 WHP for the street and keep the WTQ close as I can to the 800 mark with 14LBS of boost

besides the transmission and rear end those are all the big parts.

any comments suggestions, concerns Ect?

You could easily make that with a forged 403 and the right setup. If you're close to A&A a phone call will get you to your goals.

what about my goals for show off mode? p The idea for me in all honesty is to keep the TQ numbers around the HP numbers in other words if my car makes 800WHP I want to be close to 800WTQ ya know what I mean. I know theres alot of guys who are making 800WHP and more with engine's that are just at the 400CID mark or even smaller but based on what I see those smaller engine's sure they make the HP but the TQ suffers. Dont get me wrong I'm not saying these other smaller displacement guys running blowers are not making any TQ because they're making *** loads of it. I have very specific HP and TQ goals in mind all while trying to maintain some drivability. I know it can be done.

Thank you for your advice. I will call A&A and talk to them. I wanted to use one of thier blower kits anyway. I also was considering (well I will use) an ESC alchy kit too.

Based on reading (NO personal experience) I wouldn't go with the Warhawk bock. Look at RHS or ERL.
I'd also post this in the FI section.

You are wanting to do what I am in the middle of! I am in the process of building an LSX 454 engine for my 99. at this time, I am gathering the parts. I have the LSX block already, and ordered the rotating assembly, back in March. I still don't have it, but should in the next week or so. I am going with a 4.185 bore, and a 4.125 stroke. I ordered the Callies Dragon Slayer crank with nitride treatment, Diamond pistons, with coated top and sides. I am also ordering Callies I-beam rods, Cloyes coated main and rod bearings. I bought a Melling HP oil pump and a Cloyes double-roller adjustable timing set. I have a local machine shop to do all the work for me. I should have it running by spring. All I need to finish the engine is to order a set of Trick Flow 225 heads, and a water pump. I will reuse my ported FAST 92 intake and Lingenfelter 90MM TB. I currebntly have a ProCharger P1SC1, but will upgrade the head unit to an F1R.

I am setting up my compression to be 9.5:1 for more boost.

You can easily hit that HP goal with a 403 and be easier on your wallet. I'm in the mid 600's with a stock 346... corvette8189 (Billy) has hit 800+ with a 347 and stock crank.

Let us know how that World Performance block works out.......

Warhawk ?/ no don't do it.
Your also looking at a tall deck in order the get the 454 for boost. We are building a 1500 hp engine for someone right now as a matter of fact.

Does it have to be 454 cubic inches ? We are using an ERL deck pinned mains the whole nine yards.. 1/2 studs.... The RHS block is a little more money, your talking about a $9000-$11,000 shortblock either way. Dragonslayer crank, h/I rods etc...


We build them all the time and would love to help you with your project to make sure its gets done right. If we can be of service let me know.

Consider the L92 heads as they flow about the same as the LS7 and are way cheaper and as you are going to be boosted it wont really matter. I went with the F1C supercharger as I was told it would be easier to spin and can make lots of boost. I'm running 20 lb on a LS7 427 block. You will love the power. cheers and have fun doing the build

MVP'S ZO6

no bueno on the warkawk block? Who's had trouble with it? please share. I just want to do this right.

MVP'S ZO6

WOW! My question is why isnt everyone running these. these are some bang for the buck ya know. What kind of power are you making?


I may consider doing a 427 but the idea was for me to beable to keep the
HP levels at 800WHP torque as close to 800WTQ as I can @ 14LBS of boost I understand there are guys running less engine with more boost and making those kind of HP numbers but I will see a guy post a number something like 800 WHP and 670 WTQ. that ante going to do it for me. Also I want to be able to make 4 digit numbers with a pully swap and a tune change. simpally for the cool factor and bragin rights. plus it would kick *** to say I have a 454 in my vette. Please dont think less of me cuz of this. I'm actually very knowledgable about what I want and about how to build a car. I just want to get oppinions of those who've been there and done it.

someone reccommended the L92 heads as opposed to the LS7 heads. and comments? Whatever head I get is going to have work done to it by my buddy Dave Endrigo at flowtechnics.

099blancoss

Well you can do the 454 but its going to have to be the tall deck and it adds a few nuances but nothing that can't be handled. I would use the RHS block as a foundation or the ERL. Heads I would be looking at some of the Carry's heads who is now at MAST.

MVP'S ZO6

What kind of nuances are we talking about? Also, mast seems to have a plethora of cylinder heads are you talking about these? http://www.mastmotorsports.com/2010/...sembled&id=377

moderators can you please merg this thread with the other one I made just like this in the forced induction section?

heres a link to my other thread.

Thanks!

In regards to my LS7 427 with the F1C I am making 850 RWHP with a conservative tune, add the Nitrous and 996 RWHP and 899 RWTQ and that gives you well over 1100 flywheel hp..

MVP'S ZO6

What is your static compression ratio?

RHS Tall Deck!!!!

TonyVette396

Just a thought that no one has mentioned...what will header clearance be with the tall deck block? I did a tall deck big block Chevy in a 69 Camaro several years ago and the standard big block headers were snug against the floorpan because of the tall deck. Could this be a potential problem with a tall deck LSX in a C5 as well???
