I looked at the M3D site and could find little technical information. I like the looks of the head & valve cover, but how much finish work after printing did it take to get to the point you showed? Is the printed surface smooth?
Since the original issue of that kit was of the Gene Snow car, it's only natural that the chassis is more correct for that version than the others. For the sake of accuracy, I would build the Snow car.
As stated earlier, the best Cragar SS wheels come from Johan. I especially like the wheels in the original issue AMX S/S car. The detail in the center caps is unbelievable and the overall shape is spot on. In the AMX they have both shallow and deep offsets, perfect for 70's SS and PS cars.
Johan is often overlooked for quality well detailed parts because the kits were issued over and over and the molds were in bad shape, but for their day and even into current times, the detail and shapes were great.
Consider that in the 60's they were producing kits with combustion chamber detail in their Hemi heads, Cylinder detail in their Oldsmobile blocks, etc.
For 60's and 70's SS and PS builders they produced the best wheels including fantastic Keystone Kustomag Klassics in the Sox & Martin 71 Cuda, Great Fenton slots, and even superb Motorwheel Spyders in the Eddie Shartman Maverick.
For T/A racing in 67 and 68, the Penske cars ran American Racing 5 spokes, so one of the Revell C3 Corvette race cars would be a good kit for those. In 67 they ran a flat (not the SS) hood with a NASCAR-like cowl induction air cleaner ducted into the cowl panel. They also ran yellow stripes.
So we need a base car flat hood, AR 5 spokes, Stripe decals, etc to make an accurate 67 Penske car.
Didn't the original issue of that kit include the optional parts and decals to do the Craig Breedlove Speed Record car? If so, I hope Round2 includes those parts too. What a surprising and interesting release!
Judging by the picture above, it looks like the original six pack scoop was cut open. So it was probably a modification done later in the season. I lived in SE Pa as a kid and made many trips to Englishtown. I saw the 70 run, and I do remember the crossram, but I also realize they were race cars and they changed throughout the season. I can admit when I'm wrong, it looks like it did run during the 70 season in the configuration shown on the box art.
Oh yes, it's still very nice to have and I will buy several. I did not mean to put the kit down, hell, I haven't even seen one in the flesh yet. I was only commenting on what a saw of the box art and read. It's nice to have a kit of the subject at all.
71 Barracudas (not Cudas) didn't have gills either, so the fenders would have been correct for a 71 also. It is possible that one of the 70's may have been converted though. Remember that S&M shop was basically a factory. You could actually order a P/S car out of the catalog, so building a new car or cars each year would have been a breeze. S&M supplied cars to Ronnie Lyles, Reid Whisnant (sp?), etc.
Understand that I haven't actually seen the kit, just box art. I'm also basing my comments on what I read in this thread. There were actually two 70 P/S S&M Cuda's (as well as Dusters) One Cuda had chrome bumpers and the other had an Endura front bumper. I have a picture around here with S&M posing in front of two transporters loaded with both Cuda's and Dusters. I also have an S&M catalog which shows a background picture of a Body-in White 70 Cuda next to a brand new Hemi Cuda street car. They stated that it was easier to start with a stripped shell and transfer all of the required stock components to the shell than to strip a street car to build the race car. This is very common practice today, but fairly uncommon then, especially on what was primarily an SS car built for heads up competition.
No onto the kit based on what I know of it. The real cars (at least in legal NHRA P/S trim) used cross ram manifolds in 70. I read in the first post in this thread that the kit had a tunnel ram. Is that true? S&M may have used a TR later in the year or for match racing, but all of my references show a cross ram in 70. Second, the box art shows a hood scoop with an open front. The 70 car in all of my pics shows a standard Six Pack scoop. FYI the fiberglass parts for the S&M cars came from A&A Fiberglass here in Atlanta. I can confirm that the hoods that came from A&A had standard Six Pack scoops. again, for match racing anything goes, so the pictured scoop may have been used.
If the above inaccuracies are true, then the aftermarket needs to come to our aid with a correct intake and hood at least.
EDIT- I just Googled the Cuda and I see pictures of the car restored and it indeed looks like it had a TR and opeen front scoop. Revell must have looked at the restored car and included parts that weren't on the car in it's most raced configuration .
