Pelle,
 
Which heads do you have?  I can run a Dyno2000 simulation with your
setup
and get some guesses.  Give me a "parts list" of the engine builds you
are
thinking of.  If you have Cam specs or the actual cam name I might have
them
stored already.  I took some guesses as to components and came up with a
425
HP combo off the bat.  I used what you gave me and assumed Edelbrock
Performer heads and a high performance hydraulic lifter cam.  The
program
assumed lifts of .504/.479 and the engine is guessed to have 424HP at
5500
RPM, but torque starts at 411 at 2000 RPM, peaks at 450 at 4000 RPM, and
drops to 366 by 6000 RPM.
 
Not an actual engine to copy, but at least it gives you an idea what you
can
look into.
 
The only 402 file I have is from an engine with a roller cam.  It has GM
Rectangular port "188" heads, a 850 CFM carb with a dual plane intake,
small
tube headers, and Comp XR282HR cam.  Numbers are:
 
RPM     HP    TQ
2000   168   442
2500   218   457
3000   268   469
3500   322   484
4000   371   487
4500   413   481
5000   436   458
5500   432   412
6000   410   359

	Does anyone have a 402 (.060 over) 2-bolt main with approx
400-500
hp
	which i can copy?
	 
	I'm asking because when i get my block back from the machine
shop
	I'd like to get "bolt on" hp without too much
hassle/experimentation.
	 
	Im planning to raise the comp to 10:1(new pistons), keep the
original heads, my
	800 cfm Holley, my Hooker headers with 2'' primarys and my
Edelbrock
RPM performance Intake.
	 
	I know i've been pestering you guys with this before but I still
need some ideas/input/advice!
	 
	 
	Best regards
	Pelle
