The grooves looks a little exaggerated but they look better than the old tires wich had totally smooth sidewalls except for the lettering. The Bandag tires were retreads and how the sidewalls looks could depend on what core they used, I have seen several different versions for the Malone race trucks, he must have gone through many sets of tires over the years and they were most likely different from set to set. I miss one script on the decal sheet tho', I can't find the "Tyrone Malone Mr D.D.D." for the rear face of the small duck tail spoiler on the rear body work anywhere.
Yes, the Slixx Sox & Martin decal sets are way better and more accurate than the old Jo-Han decals, the Slixx set to look for is the #SM3/1483 and it will do the 1968-69 GTX's and Road Runner's, and the 1970 Superbird
But if you want the original Jo-Han decals, most of the later reissued from the 90's of the Sox & Martin 71 'Cuda kits had wrong decals wich originally were for the Sox & Martin Superbird kit, so they are not so hard to find if you want them.
I think I have read somewhere that the Revell 1969 Camaro tooling is based on the Monogram big scale 1:12 Camaro and scaled down to 1:25th scale when they did these kits. In my opinion the Revell 69 Camaro kits are very good and with the versions released you can do almost what ever you want with them.
The versions from this tooling so far are: Z/28: both RS and standard grille, small block with cross ram option and headers, cowl induction hood, rally wheels. Yenko SC: standard grille, big block, headers, one snorkel open element cowl induction air cleaner, cowl induction hood, American Racing Torque Thrust wheels. Baldwin Motion: RS grille, big block, headers, Motion fly eye air cleaner, L88 scoop hood, side pipes, rally wheels. Convertible Indy Pace Car: RS grille, big block, headers, same air cleaner as the Yenko, cowl induction hood, rally wheels Indy Pace Car decals, flags. Convertible: Same as the above except for the Pace Car decals, the flags are still there and decal sheet has hounds tooth insert decals for the seats. COPO ZL-1: standard grille, big block with headers, same ari cleaner as the Yenko, cowl induction hood, steel wheels with dog dish hub caps. The 69 Convertible and Z/28 have also been done in 2 'n 1 versions with larger wheels.
The newer AMT 1970 Camaro kits came in two versions, the Z/28 and the Baldwin Motion and both has the small bumper RS front. The Z/28 has small block, front spoiler, low one piece rear spoiler, Z/28 wheels, flat hood The Baldwin Motion has big block, headers that goes into side pipes, Motion fly eye air cleaner, L88 Scoop hood, front spoiler, tall 3-piece rear spoiler, Cragar SS wheels and good Mickey Thompson tires, Lakewood "slapper bars", the early kits doesn't have the Motion Spear decals but the recent Round 2 release does.
The AMT 67 and 68 kits are decent but not up to todays standard, but they are for sure buildable.
It's a Volvo D12 to upgrade the Italeri FH12 made by P&B Models from Poland. I plan to use it in the Volvo VN 780 wich have no engine or gear box...just a dummy, I would really have liked to have a D16 but there is none available as far as I know.
No the Revell kit doesn't have a tunnel ram, Sox & Martin used a custom made individual runner magnesium intake manifold without plenum in 1970, the JoHan Sox & Martin kit has a Weiand magnesium intake manifold with plenum as S&M went to that for the 1971 season.
