One Piece At A Time



 
 
 
 


 
Robert Renteria, is from Silver City, New Mexico, and, like the rest of us, has been improving his 71 Duster for quite a while now.
Underneath, a 35-spline, stock length 8 3/4 houses 4.56 gears and the tires you see are 29x10.5 MT slicks.
Summit drag shocks provide dampening and a pinion snubber helps out the factory springs.
Robert tells me for stock springs, the car hooks great... Lets hear it for modern tire technology.

The chassis has assistance from a 10-point cage and 5-point RCI harnesses keep the driver in the 'glass buckets.
A B&M ratchet shifter changes gears, and a 6" tach with a light tells Robert when to use it. A rev limiter is employed in case he's sight-seeing instead of shifting :)
The B&M cable is connected to a 727 which is helped along with a B&M shift kit.
A 9" 4000 stall GER converter makes for crisp launches.

 
 Unfortunately, Theres no underhood pic, as an engine freshening turned into a bit more than that.
The 440 contains a steel crank, polished Six-Pack rods and is balanced with TRW 10:1 forged pistons. Ported and polished 906 heads recieve input from a 284/484 Solid cam. The induction system starts in the trunk with a 16gal fuel cell. Two Holley Blue pumps push the fuel through 1/2" lines with one ending at the 750 Edelbrock carb and the other leading to the 250 HP NOS plate. Robert does say that he hasn't run the NOS at the strip yet. Hooker 1 7/8" fenderwells get the exhaust down underneath to the two 4" straight pipes...imagine how this thing sounds!
It's all ignited with a standard MP electronic ignition kit.

The car currently runs 12.13 @ 110MPH without the NOS.
Robert's currently adding fully ported and polished 915 heads with 2.14 & 1.81 valves , a 528 solid cam , forged 12.8 Ross pistons and a TCI trans-brake.
All this should knock quite a bit off that ET, and if he accidentally bumps that NOS button, I bet we'll see either low 10's or the biggest burn-out ever :)  Perhaps an engine pic will surface after the upgrades are done. Watch for an update here in the future.
