Awesome looking Oval, Nobbe! That stance in the paddock with the stinger looks the business.
Looking at your 2165cc (78x94) combo, here are a few critical points for a street/strip car turning up to ~7900 RPM on slicks:
* Valvetrain: With 0.610" lift at the valve and high-RPM targets, you’ll need a stout, properly set up dual valve spring package with titanium retainers and lightened lifters to prevent valve float and protect that valvetrain geometry.
* Bottom End Defense: Crank whip at nearly 8000 RPM will quickly pound out center main bearing saddles in either a magnesium or aluminum case. Your absolute primary defense is a quality 78mm counterweighted crank paired with precision dynamic balancing of the entire rotating assembly (crank, flywheel, pressure plate, rods, and pistons). Shuffle pins or an aluminum case are only supporting mods.
* Flywheel Retention: Launching hard on 26" slicks delivers massive shock load. A standard 8-dowel crank will not survive repeated clutch drops. Step up to a flanged crank or a precision wedgemated crank and flywheel combo.
* Clutch Management: Pair your pressure plate with controlled clutch engagement (progressive slip and proper clamp load). Squeezing rather than violent dumping saves your ring & pinion, protects the trans gears, and drops your 60-foot times dramatically.
That close-ratio stack (3.78 / 2.30 / 1.56 / 1.21) with the 3.88 and 26" slicks should keep you right in the powerband through the traps. Plug your tire growth and shift RPM into the forum calculators to verify your final drive crossing speed!
