Please help

 

I reckon it will fall on it's **** at revs.
You have a big breathing top end setup ;
Heads /Intake / carb good for 7000+ ( Vic Jnr recommended operating range 3,500 - 8,000 )
while your cam operating range is ;1,800-5,800 ( in a 350 , lower in a larger engine)

So why have you picked a intake / carb combo that works at big revs.
A Air Gap or similar intake would make better power down low without killing top end

What stroker crank do you have?
A 30 over 400 is 406 .
IF it is stroked it would be larger.

 

i would agree, needs more lift, tad more duration, atleast a 3k stall, and change the intake to a RPM air gap. Also put your goals higher then 420hp

 

thanks guys im very new to this and i appreciate all of the help i think it should run good

 

yea you should def. match head intake and cam... for your purpose and each other
