Sir;
To me your post with the added response makes no sense to me at all.
You mention is of strip only but the questions you ask sure do look like you are talking about a street car.
Ditch the Dual Plane Intake. Don't use a Rectangular port on oval heads, no matter how many people tell you it works. You can buy good Team G and Victor Jr. on ebay for very little money.
Why do you want low compression?
How do you figure a piston with a .100 tall dome (small) will be 9.1 - 1 compression with those heads?
You have the potential of a 10 second street car at your weight level with the parts you have if you put it all together right and give it some compression and lose your ideas of racing with 92 octane gas. You could put it together right with what you have with 10.60 - 10-90 -1 compression and run 92 octane and run 11's all day though.
Example;
In 1978;
Car with driver 4,200 lbs 11.50 -1 compression ratio (modified 13.50 - 1 pistons) compression = best of 11.48 ET
Daily street transportation altough a little ragged.
781 oval heads mild port work, bowl work, 2.19 intake valves 1.88 exhaust valves. Flat tappet cam with .640 in and .620 ex duration at .050 was 264 and 268 stick 4 speed car. mildly modified vacuum 780 Holley on a Edlebrock Tarantula Single Plane . 4.56 gears using 10" x 30 inch slicks. MSD 7 & Pro Coil.
Weight was;
LS-6 frame (beefier)
Cowl Induction Steel Hood (Heavier)
Steel Blow Proof Lakewood Scattershield (heavy)
40 lb flywheel (heavy
