Dale,

Very cool. It was nice talking to you at the Borchardt's show. You should post some pics of your buddy's dune buggy to entertain the troops here.

Do you have a picture showing the valve covers? Curious what they say.

What are the specs on your engine?

Be sure and let us know how it dyno'ed.

How tight are you planning on spinning that thing?? Single plane and a disty conversion:hail: High rpm's here we come!!!!:willy:

[DB Z28]

6800 rpm

[mazspeed]

That looks killer. Only thing that worries me is if there is enough belt wrap on the water pump at those rpm's.

[Stang's Bane]

6800 rpm
What camshaft did you go with??

[DB Z28]

Here,s the start of the list on whats inside

GM LS-7 GM Block

Ati balancer
Mahle Rings and Pistons
LS-7 heads reworked
11.1 CR
Modifed Rocker arms

Cool,
I went with the Callies crank and rods too, very nice pieces. I assume HS did the rockers??

Very anxious to see the final numbers for this.

[deuce_454]

what is the point of ditching the GM LS-7 titanium rods in favour of a set of callies???

[DB Z28]

Their was rods and pistons failed in the wrist pin area. from what I was told.when you start pushing it over 625 hp.Mahle pistons guys also said their was problems. As for going to a Callies crank or stock crank . On a stock crank you would have to drill out the crank so much to add weights it would make it weaker for the heaver rods.

[Stang's Bane]

Any numbers yet??

[DB Z28]

waiting for a differant cam and more intake work

[DB Z28]

Ran it today it was Hot and Muggy
It pulled 711.7hp at 7100 rpm
Max torq 610@5521rpm on pump gas 93 oct At 6628 rpm at was at 700hp
1 7/8 headers tri y with 3in exhaust with h balance pipe no open headers
sounds realy nice will have more pictures later
We hit the 100 + hp per liter on pump gas

Do you have any Dyno Charts you can post?

What type of Coin does it take to get into something like this??

Very Cool Engine,

Thanks,

Very cool. The single plane intake obviously moves the RPM range up from the stock LS7 intake - a stock intake LS7 won't make peak power much past 6500, no matter how big the cam is. And 711 on an engine dyno is really screaming!

What EFI are you using again?

[DB Z28]

we are using the Panthera EFI . The stock LS-7 intake was ported a lot to make it work right, The two in spacer on top gave it almost 20hp. Wagner sells the whole package for about 18500.00 it comes with a wiring harness and Panthera EFI and front end assembly pullies, brackets, power steering, alternator its the same that DSE uses .Its really a good deal.
