My 1980 Dodge Diplomat coupe (3600 lbs street weight) ran a best of 13.13@102mph. The drivetrain combo is: 360 motor, home ported cast iron heads, 2.02/1.60, hydraulic cam, Hughes Engines HE3844AL (238/244 @ 0.050", .536/.540 lift, 108 LSA), 9.8:1 static CR, 165 psi cranking, Holley Strip Dominator intake, Carter TQ carb, 4K stall - 9.5" Dynamic converter, 727 auto, 3.91 SG rear end. I then switched to a Perfomer RPM intake, which I think would dip the car into the high 12's (street butt-meter said it felt much stronger at the bottom-mid-range) but I never got a chance to run it though.

Over the past couple of years I picked up all the parts (short of pistons) I need to build a stroker motor (408"). I was going to hold-off on doing this until I was ready with my W2 heads (long valve econo versions), but that is still some time off.

So over the winter (yeah, no garage work causes idle mind to think "BIG" ideas...lol) I figured I might give the stroker build a go but based on my existing OEM iron heads (same heads I'm currently running in my combo).

The heads flow:
LIFT I E

0.100 67 57
0.150 99 79
0.200 130 104
0.250 162 125
0.300 189 140
0.350 215 152
0.400 235 160
0.450 253 167
0.500 262 172
0.550 261 175
0.600 248 177

I also have a Comp Cams hydraulic roller cam available, which I'd like to try having never ran a roller before. It is very close to my current Hughes HE3844AL grind, just a wider LSA.

The roller cam specs (custom grind CRS 13084B/3039B HR 112+4) are: 0.548/0.545 lift, 240/248 dur@0.050", 290/300 advertised dur, with 112 LSA ground 4 deg advanced.

Evan though the LSA change from 108 to 112 implies I will have a more broad torque curve with less peak I am thinking the extra inches of the stroker will make up for the less peak, and since this is really a street car I am fine with more usable power up to the 6K range.

So I'm looking for the forum wisdom regarding the impact of the two below combinations in comparison to what is my current setup:

COMBIANTION #1
==============
Keep everything the same (heads, cam, drivetrain), but go to stroker build and bump the CR to 10.5 static.

COMBIANTION #2
==============
Keep everything the same (heads and drivetrain), but go to stroker build with roller cam and bump CR to 10.5 static.
