"the next step" 440 performance build.

I have a 68 valiant that I built as a street/strip car about 4 years ago. We used a 68 newyorker as a doner car for the 440 and TF727. Im putting a plan together to take it to the next level and would like some opinions.

Current setup:

- 68 440 block
- completely stock shortblock with factory flattop pistons and 906 heads. (rebuilt with new bearings, rings, etc.)
- XE274H cam
- Edelbrock performer intake manifold
- Holley 850 mechancial secondaries
- custom "deep sump" oil pan
- hooker supercomp fenderwell headers
- Mopar electronic distributer
- MSD 6AL-2

- rebuild TF727
- Cheetah manual reverse pattern valvebody
- 3500 stall TCS torque converter
- B&M pro-ratchet shifter
- B&M trans cooler

- Chrysler 8 3/4 housing
- 4.10 gears
- Spool
- Moser axles

- custom 3 leaf rear springs
- Competition Engineering slide-a-link
- Competion Engineering adjustable rear shocks set at 50/50
- 6cyl torsion bars
- Lakewood 90/10 front shocks

Wheels & tires:
Front: BFGoodrich radial T/A 155/80/15 on 15x4 Weld Prostars
Rear: MickeyThompson ET street 11.5x28 on 15x8 Weld Prostars

Current 1/4mile performance:
12.19 @ 106
1.67 60ft
race weight :3360lbs

OK, now that you know the car, Im looking at making some changes to the engine and would like your input.

I bought a set of ported 906 heads that have been fitted with 2.14/1.73 valves and have extensive bowl and runner work. I am thinkng of running these heads with a Comp XE294H cam, Mopar M1 Intake manifold and a Holley 950hp carb.

I want to make more power in a higher RPM, and I think this combo will do it.

I would like to keep the short block stock except for a set of ARP rod bolts and run on Chevron 94.

Give me your input with any combo using those heads and rotating assembly.
