Making the 600-700hp is the easy part.
The combo outlined in the opening post will easily do it.

10’s....... also relatively easy....... if no compromises to the gears, converter, tires, fuel system, etc, are involved.

Each “streetability” compromise is a bit of time added to the slip.

If every combo ran exactly what the owner thought it should, there wouldn’t be any of those “help me get my car to ET better” threads(and I wouldn’t get as many phone calls and emails along those same lines).


As an example.....GY3...... 511, cnc ported heads, roller cam...... should be pretty darn close to 600hp.
Car should be in that 3500-3700lb range....... not running 10’s.


this about sums it up .

choose a goal not a HP , then accept what it needs to get there .
my pump gas 440 ran to 10.80s @ 3700lbs with a .520 nett lift solid flat tappet . Daily driver . Drove interstate multiple times .
