After going back and forth on auto vs manual, I puchased a T5 z-spec tranny. I have a 408W with Edelbrock Victor Jr heads, RPM Air-Gap, 800dp Holley, and 3.89:1 gears. Since the T5 has .59 od, I will swap to 4.10:1.

Intake Exhaust
Valve Adjustment 0.022 0.022
Gross Valve Lift 0.56 0.56

Valve Timing At 0.015
Open Close
Intake 41 73
Exhaust 81 33

These Specs Are For The Cam Installed At 106 Intake CL
Intake Exhaust
Duration At 0.05 248 248
Lobe Lift 0.35 0.35
Lobe Separation 110

Thanks
Alton

This car will be on the street more than the track. It has manual disk/drum brakes.

282S would probably be a better compromise.

I think the 294s would be good in the 408w. But I don't drink coffee on my way to work.

On a side note, I'm also running a T5-z (courtesy of SteveW) and love it. I'm running it behind a mildly built 289 w/ 3.50 gear and traction is an issue for me, I need more tire. With the torque your massive 408 will produce I would definately run it w/ your 3.89 gear and see how you like it before swapping in the 4.10. You will have serious traction issues w/ the 3.89 no doubt. My car is also a street car, I plan to make my first pass down the 1/4 mile very soon.

Matt,

Glad you like the t-5! It definately wouldn't have worked behind the 408w we have now.

Alton,

We run a 3.89 gear behind the 408w in the '66. It's almost too low a gear with the 26" tall slicks. Goes thru the traps at 6700 rpm @ 124 mph. 3.70's would take advantage of your massive bottom end torque.

The t-5 will only compound the problem, the larger cam may help by killing a little bottom end. But that low 1st gear will be wasted, you might as well plan on starting out in 2nd gear.

Thanks everyone. Comp tech told me they don't make the 294S for the 351W. I found it on their site by searching 35-335. It is not in their parts database. Long story short they gave me a custom grind number that was similar on the intake but taller and longer on the exhaust. They also told me to use 1.7 rockers instead of the 1.6s I have.

I was thinking about waiting till I got it running. What tire do you run? I have 275-50-15 BFG Drag Radials and Detroit Locker. Keep us posted on your track times.

My car currently has 235-60-15s on the back. I got them used w/factory steel Ford (truck) rims for $50. They will roast down without popping the clutch.
