How did you acquire the engine?? Anymore available?
I got the engine from ebay missing many parts including a head and other bits . The engine originally came from Lister bit they claimed they had no parts left when I rang them so assume they have no complete engines either.

What do you need?

More cubes than LS2 and L92, then the stronger LS7 platform for my blower should make it a potent & reliable performer at around 800rwhp with torque #'s not to far behind. What's more to me is the "Fun Factor" of revving very quickly to 7.5k or maybe a little more if feasable. I love the sound of rpms and the mptor would have more than enough torque to tool around town in without having to rev. I will keep my 3.42 gearing and install a built MN6 with G-Force 5th & 6th gears. Defintely a combo that I plan to take to "The Texas Mile". This car is not being built for the 1320, but just for the "Fun Factor" with some road course driving events and an occasional trip to HRP(maybe twice a year). I have not even started buying the parts yet, just seeing what you guys think of this combo. Maybe by the time I start to build, the LS3 with be out and may be the block of choice, Dunno.
Good luck on your build whatever it may be!

I have been to NHRA Nationals at HRP many times and you're right,Top Fuel is like dynamite exploding in the cylinders and you have to have uber strong internals to handle the power. Nitromethane is why they rev so quickly. Have you ever heard a Formula 1 Engine Rev to 20k rpm, IMO one of the best sounds in the world: short stroke, small bore, and lightweight internals. Top Fuel & F1 are both at the cutting edge of their respective classes & types of racing.
I'm just kicking around the idea to have a FUN combination, not to be the fastest on the street. Indeed if that were the case I would have the new LSX Stroked to the Max with N2o & a blower. I am not trying to start a debate on which type of engine is faster, I was merely asking about De-Stroked LS7's because I like the way they rev quick and IMO make a car fun to drive

Anyways, a fun combination for a street car..... LS2 block, L92/L76 Heads Intake and a light bottom end with a stock crank and not to large of a cam. Now that will rev and have fun.
There might be some small port LS7's coming out here soon and those would be great if they can go on small enough bore.

I saw someone mention the Quaife Diff for the vettes! Yay, finally something i can have input on! GET IT. I've loved mine, had it installed back in March in a Stage 5 DTE, the best IRS combo you can get for your vette, DTE will not install the diff, but you want their parts, the clutch plate diff is a piece of junk personally, and I've been accustomed to the ATB diffs for years (don't worry about the rear, except for the actual Getrag case haha).
Pricey, but worth it. I found out well after the fact that theres a shop out in Cali that actually does Quaife Getrag rears for the car, PM if you need the name of that shop.
and holy crap this thread came out of the grave...
What'd you end up settling on?

but it will be a HUGE bore, short stroke with low compression and lots of boost from a front mount turbo.
