i have two builds in mind which would be better.

1.441-445 with brian tooley tfs 245 mast 4500 intake llsr cam or hydraulic roller
2.ls3 416 with frh rhs small bore ls7 with mast 4500 llsr cam or hydraulic roller

 

Better for what?

 

which will make the most power and be faster at the track

 

I vote option 1, LLSR. The additional cubes will make more average power and those heads will certainly be able to feed the motor.

 

It's probably pretty close. I think those RHS heads are really good, but I don't know if they'll offset that deficit of 20+ cubic inches. Now if those RHS heads went on the 440ci combo...

 

I say number 1!! TFS heads just don't shine on a shop dyno...... they kick @$$ at the track too.

 

Yea that's what I really want to do but 5500 on the bottom end and 8500 on the top end is not in the budget right now but I may just wait another year and just do the 441 with the rhs heads

 

This is true

 

I have some LS7 headed combos fall short of 600 horse at the tire.....
While Vengeance and others was breaking 600 horse at the tire YEARS ago with a nice fat amount of torque down low in the RPM band to boot

 

all i want to do is run 6.20 or quicker on motor and mid to low 5s on nos thru a 4l80e in a 31-3300lb car street driven and ill be happy with that

 

A thread you might interesting then...

i talk to txcamss alot about the setup but im not sure if it would run what i want with the 80e and a stall that will take nos.he has a pg very loose stall

 

Either cubic inch combo will do it. The bigger engine will do it with less RPM. At those RPMs and power levels I would be looking at the LS7 stuff. I would not bother messing with cathedral at that power level. There is just no point in it. The LS7 format is just superior.
