While I am waiting for title issues on my 1970 Road Runner :angryfire:, I have been thinking about the engine/drive-line build.
My starting point is a stock, 80,000 mile 335 HP 383 with a 4 speed and 3.55 8 3/4.
Goals: 400+ Horsepower and 20 MPG highway, keep the original 383, A-833 and keep the air grabber functional. Run on premium gas (92-93 octane). I would like to make the car a really nice reliable driver car with a broad, flat torque profile. Do this without sacrificing the true Road Runner "spirit" - car still needs to leave a traffic light like the muscle car it is!
Some starting thoughts:
Engine: Leave as 383 CI, short block fairly stock, except perhaps a higher lift/duration cam (specs?). Add aftermarket aluminum heads (which?), dual plane manifold, headers and fuel injection. Add 2.5" exhaust with X pipe.
Transmission & Rear: Stock except add a Gear Vendors overdrive.
Having said the above, I am no expert, and don't know ideal specs on anything to achieve the stated goals.
I'd like to hear comments and suggestions from the gurus on the forum!
Thanks in advance!
