[PICS] The BADDEST Street Attack 500 to date 701hp/677tq NA on 11:1CR & pump gas! Here is what it takes to make a true 700hp, 11:1 compression, pump gas engine without any funny business. Keep in mind that this is a 500ci engine with a 4.500" stroke so we are not revving it very high either.
Street Attack 500
Custom camshaft - a little more aggressive but still streetable, still hydraulic
Kinsler crossram manifold - makes it less streetable
11:1 compression
March front drive
Katech carbon fiber valve covers (prototype pictured)
Show prepped intake runners, valley cover, water pump, oil pan - Atomic Orange
Painted engine block/heads
Going in a 1963 Corvette
To be featured in Vette Magazine
You may ask why the dip in the torque curve. It is related to camshaft/intake/calibration. We may be testing more with a Motec to tune that out a little better. Keep in mind that the "dip" is still over 650 ft-lbs at its lowest point.
This engine makes our Desert Attack 500 look very promising. Imagine 14:1 compression, more aggressive camshaft, and a Kinsler vertical manifold. 750hp/750tq here we come!

Or maybe you have to be loaded to consider asking that question...? That intake is sick.

for the love of god.......
Simply amazing, especially the torque curve, even with the dip that's a true stump puller!
How hard has it been to get the ITB's dialed in? I've heard they are a b*tch to tune but once right it far outweighs anything else.

Once the customer gets the engine, they will be building airboxes to contain the runners. That is where the filters will be housed.
