Re: my 82 trans am
The pic's shown are of my std port 23 deg headed 406 ci sbc (668hp) The nitrous system was just for looks. It was never used but the car ran 10.00 @ 134 with this set up. The car is 3780 pounds with driver running stock type bolt on suspension parts on a 9 inch slick 1.36 60 ft times . I had to sell that engine last year when someone offered me more money then I could turn down for it . I started over and built a 434ci sbc i'll post some pic's and the build info

Re: my 82 trans am
Here's my 434 set up and what in made
Short block info (8.990 deck 4.155 bore 1670 gram bob weight)
Dart little M block with steel main caps
Scat billet crank 4.00 stroke
Scat 6" H beam rods with L19 rod bolts
Wiseco 13.9 to 1 custom pistons
Comp cams 12-970-9 679/645 lift, 279/286 @50 on a 108
Heads
All pro RR227WSP with 390 cnc port program 249cc intake runners 66 cc chamber 2.76min. csa. valves are rolled 1.5 deg and the head is rolled 1.0 deg so the head now has a valve angle of 20 deg. also has a dowel shift toward intake of .085
here's the flow numbers
2.125 intake 1.625 exhaust @28 hg
.100 79.65 x 65.00
.150 112.10 x 91.00
.200 146.03 x 117.00
.250 184.38 x 141.38
.300 214.17 x 167.38
.350 244.26 x 191.75
.400 274.36 x 211.25
.450 295.54 x 225.88
.500 314.40 x 237.25
.550 330.91 x 245.05

The intake is a Elderbrock 2949 super victor with a 4500 adaptor fully ported
stage 9 biggs performance 1050 dom
peak hp 720.2 @6800
peak torq 605.3 @5800
avrg hp 692.06
avrg torq 583.21
avrg bsfc 0.440
Average results from 5500rpm to 7000
It has such a flat power curve
We removed the intake and I fixed a port mismatch issue and reworked the center dividing walls and plenum,and added a vac pump and picked up 32 more HP and 4 ft pd of torq
752.4 @7000

Re: my 82 trans am
are you going to run any of the Ram Racing N/A Shootout type stuff? that's what that car looks like it's setup for!
has your engine been moved back? is that why the cowling us cut up?

Re: my 82 trans am
Well guys I'm back to working on the car again after a long layoff due to health issues . Ive got the engine almost ready . It's all freshened up with new valve springs and a different cam. I did a lot more work to the intake and heads . All I have to do is put the intake and rockers on and the engine is complete . I ordered a Spohn torque arm and trans crossmember today . I'm not going to dyno the engine this time it's just going straight into the car . thou I'm still having health problems that will keep me from ever running my car faster then 10.00. I.m just happy to get back out ...
