Mopar questions

[mnwildpunk]

I have a few questions and instead of a new thread for each question; I thought I'd just lump them together.

#1. I thought I heard at one time chrysler products back in the day their underbodies were not painted and you would only have overspray of the body color. So if this is correct what color should I spray it? A steel color or gray?

#2. The monogram 70 roadrunner

kit I have comes with a 440 six pack.

I know this is an RB engine. I want to make a clone of the car I used own which had a 383 B engine. I know the 2 engines are a lot alike. So I was wondering if I can convert the 440 to a 383 and what mods would I have to do to make it a 383

Thank you

Pretty sure the block and heads, distributor position, etc. are plenty close on a 440 to pass for a 383 in a model. Specifics like carburetion, air cleaners, accessory location, smog equipment, etc. would possibly differ.

Here's a good starting point to research your particular application.

As for the right underbody / primer color, have a look at the chassis shots of this car.

Though it's heavily undercoated, SOME of the chassis shows a red-oxide primer. IF this is in fact a 'survivor', or even if it's a very well and thouroughly faked counterfeit (don't laugh....I've seen an entirely FAKE Corvette C2 Grand Sport roadster, passed off as the real deal, and I unknowingly made fiberglas parts for it) it's a pretty good bet this is the right Mopar primer color for the era.

There is no one correct answer for all uni-body Chrysler cars, so we'll start with that disclaimer. In the late '60s (at least, maybe earlier) Chrysler used dip tank for its uni-bodied cars, so they should be fully primed underneath at a minimum. How much body color got on the underside varies, but generally speaking, they were never fully covered, so there should be some primer still visible or exposed. Areas such as the transmission tunnel, above the gas tank and in the "shadows" were rarely covered.

If you want your model to look believable, prime it all, then imagine you are spraying a 1:1 car.

You will need a single 4-bbl (or 2-bbl) intake manifold, carb and the specific air cleaner you wish to use, but otherwise the 440 engine can pass for a 383.

Ok thanks guys I have an intake and carb I can use but do any after market resin places sell the dual snorkel air cleaner cover

I think the AMT '71 Dodge Charger kit includes a dual snorkel air cleaner.
