These are short OEM style valve covers for 1965-72 big block Chevrolet's. This is the "short" version with out corner recess for power brake and Corvette applications. The molded in oil cap in so many engines is a real detail killer. What I did with these is separate the cover and cap to offer the oil cap separately. I also added bolt head details using hex plastic rod.
This GM 4L60E Auto Transmission will fit Action-Modeler big block Chevy engines as shown in photo (block sold separately). Be aware this transmission has a higher bell housing an may not fit all transmission tunnels.
This is a WW2 helmet air filter for those rat rod projects since it isn't likely to fit under a hood. Comes as a two piece so you can easily paint them to their proper finish which also lets you use either one as a separate item.
