I'm sure no two people ideas and excepting the rough idle and tire spinning of Hi Po pump Gas street motor are the same
I like power, lots of it
On your deal make the builder do it your way
My last pump gas street car ran a best ET of 9.993 at 134.8 MPH corked up with the air cleaner on at Woodburn Drag Strip in Woodburn,OR about 180 ft. above sea level in late July with a DA around 1700 Ft. on ET street radials That was a 400 block storke to 4.300 with a 4,375 bore, Indy SR M.W.ports and a Indy 400-3 intake with a Holley List # 9375 non HP 1050 CFM Dominator carb. running Oregon 91 octane pump swill. That was a 1971 Duster that weighed right at 3450 Lbs. with me in it ready to race with a full stock gas tank
On your deal I would insist on using the Trick Flow 270 and use a EFI throttle body system like Andy F is suggesting, they work good I would use a Indy 440-3 Dominator flange or the Indy 440-2 intake with the 4150 flange on it depending on which size throttle body you choose. More air and more fuel = more power
Be careful on street driving it at first, that combination will make well north of 600HP and more torque than HP.
I have a 1966 Dodge Deluxe two door sedan that I fix up to sell but I haven't driven it yet, to much bracket racing It has a 3.91 stroke 440 motor (470 C.I.) with a set of the old Herb McCandless "452" smog heads with bigger valves, RPM intake, 850 Holley D.P., Hooker 1 7/8 with 3.0 collectors and a full 3.0 inch exhaust system to the rear bumper. Dana 60 with 35 spline axles and a early dana 60 Posi with stock Dana 3.55 gears with a NP833 overdrive 4 speed in the car with 275x60x15 tires on the rear. I had the rear end moved forward three inches and had the rear wheel wells stretched 5 inches to hide the rear end being moved
I need to take it to a front end alignment shop and have it aligned and check to see if the rear end is in the car square or not still
Good luck on your build
