[quote=RustyM]Ok- mini tub set up/ spring move allows me a 15x10 with 3.5 backspace. Tire size recommendations as well as Rim. Weld’s are pretty normal of course. Lot of rim companies out there but /quote] As far as rim width and tire to use is your rear end a stock width A body 8 3/4? On moving and stretching the wheel wells I cut up three other junk Dusters rear 1/4 panels to use in having mine widen, the darn multiple angles on the rear 1/4 panel sheet metal makes it harder to make it look factory than the other Mopars I have had done

I had my B body 8 3/4 narrowed one inch less than the stock A body where which is what your using, I think I used Welds that had one inch negative, one inch less offset on the inside than the width of the wheels, 10 inch wide with 4.0 inch inset on the inside, 5 inch on the 12 inch wide rims Maybe they where 4.5 and 5.5

[quote=RustyM]As we are going to run Andy’s motor plate and only have a bit over 650 hp , was thinking about using an electric water pump since car will really only see strip time.
I would use a remote pump like a Meziere, to free up space on the front of the motor.

"Anyone know exactly where to cut, or, take a pie cut out of the front of the rear quarters at the front of rear wheel wells for slick clearance ? I think I know where I want to make the cut but would like to confirm. It’s just really tight on the front side of the tire on the lowest side of the wheelwell.
I know I have seen pics, read an article but danged if I can find either."
I just followed the wheel well body line straight off to make the wedge or pie cuts.

Wheel openings: to my eye, the trick is to make them look unaltered and related so to speak to the front openings. My old SS Duster and the current project both retain the upper flared contour, but are cut starting about 2-3" below the center body line. Bottom of cut is to/flush ft of the tub. The racecar is also cut at the rear, and with minitubs & 3" relocation, 13x31s on 15x12 4BS fits fine, 14x32s would be a bit tight. Narrowed D60. Project is cut almost the same in front, none at rear, measures like it should just accept a 295/65R15 on a 15x10 (ideally 5.0BS) with stock tubs & 3/4" relocation. Stock 8.75. Both have upper lip rolled up, excess flange cut - take a good look at that area - racecar being thinner than project because I didn't want to cut the wheelhouse itself. Its flange is about 1/2" because of the stock wheelhouse contour. Racecar eliminated that and filler welded in. Contours at front/inside of tub are another interference point at around 31/32" tire. Pie-slice allows retaining the stock flange, a tight cut affect clearance only about 3/16".

My old street car, 1971 Duster, weighed 3450 Lbs. with me in it ready to race with full 3.0 inch exhaust to the rear bumper and air cleaner on. Ladder bars with double adjustable coil overs and a diagonal link, M/T ET Street Radials 315x60x15 mounted on 10 inch wide Weld Pro rims. Stock gas tank with a Magnafuel 275 pump with a # 10 AN feed to the pump, #8 AN bypass and #8 AN (1/2 O.D. soft aluminum line to the regulator mounted up front in front of the carb.) That motor was a 400 block bored to 4.375 and stroke was 4.300, Comp Cams custom ground solid roller 260@.0500 intake side, 266 @.050 exhaust side with Harland Sharp 1.6 ratio rockers that netted .700 + a tiny bit at the retainers on a set of Indy SR Max wedge size intake port heads and a Indy 400- intake and a Holley 1050 CFM Dominator. It ran a bunch of 10.00 through the exhaust on 91 octane non ethanol Oregon pump swill, the motor made 727 HP the last time it was a decent engine dyno in Klamath Falls ,Oregon at 4300 Ft. in the spring
