Hp at the rear wheel is what you want and lower et's.
But there are too many variables for rwhp, (trans, stalls, rearends, ect.)
I think the best way to measure what a engine makes is on a engine dyno.
Just my .02 cents.

Yup, all done. When I get home from Iraq I get to install it

The cam chosen by the builder will be great for a DD but is small for a 427 by ls1tech standards. hahahaha. It's the off the shelf comp LSL cam 239/247 which is pretty average for a lot of LS1/2/6 engines. Depending on how it drives I may throw something bigger in there... who knows. lol

Next time I'll use a different block and go for more cubes. Having a 427 in a Corvette just sounds right.

A 427 in a Vette or a Camaro just feels & sounds right.

What about these dudes? They got the fastest N/A LSx in the world so it must be near the top of this list?? With a 173mph trap at 440ci, Id guess atleast 1000+ hp... Anybody know any more details on the engine?
