10.5 to 10.75 CR with something around 292/300 duration with .520/.540" lift with aluminum heads that flow good numbers around .550" to .600" lift will make that 401 sing. nothing too fancy but it'll sound good.

That my friend, is much more realistic.
By the way Fuzz how are the eyes?
right ok - left well it will never be what it was just fond memories
best ever 11.669 @ 112.33 mph in 1/4 mile on 33 x 10.50 slicks and 4" lift / 7.358 @ 93.03 mph in the 1/8 mile
if you want power you need a cam with at least 240 duration or more at .050 lobe lift and 108 or less lobe seperation
I am running right now a crower solid 292fdp cam 248/250 with .500/.510 lift wleaned up cast heads and 12:1 CR
i have 352 hp to the ground and 420 ft-lb torq on a very lean run

Fuzz, what's your HP at the crank? What's the driveline power loss?
no ideal what the crank HP is it is just something to talk about what to the ground only matters to me
tranny loss no ideal I am running a th-400 manual reverse valve body with a ati 8" 4000 stall converter 5:13 gears and 33x10.5 x 15 slicks with 9 lbs of air in them
best ever 11.669 @ 112.33 mph in 1/4 mile on 33 x 10.50 slicks and 4" lift / 7.358 @ 93.03 mph in the 1/8 mile
Fuzz: [QUOTE=l I am running a th-400 manual reverse valve body [/QUOTE]
What is the object of running a reverse valve body? I just installed a TH400 in my C-5 and it is a manual valvebody without the reverse situation. Just wondering what that is all about. What is gained over the regular?
I haven't got mine fired up yet so I am still in the dark as to how it is going to perform. I have a 2000 stall speed in mine as ti will be only doing the regular wheelen. Hope that is going to be ok?

I've read that the TH400 eats about 40hp...also a 9 inch Ford rear eats more power than most.
If this new part can't break....what old part will??
Fuzz: Take a look at the specks of my cam. I have not fired it yet as when I went to fire it I discovered a cracked head at both ends of the head. I just got it back from having it welded. I would like to know how you think this will fit in for street and off road with my Cj. My heads (291-c) have been extensively ported and polished w/ ss valves with undercut stems. 2.020 int. and 1.688 exh. valves.. Also using the air gap.
