Here is a small block Chevy Edelbrock Torker 2 aluminum intake that was used on an engine for a very short time. I see no bad threads.
Designed for 1955-86 high-performance 262-400 c. The Torker II is an updated version of original Torker offering better performance. Manifold accepts late-model waterneck, air-conditioning, alternator and H. Will fit Corvette and 1987 and later stock. Will NOT fit 1987 and later cast iron heads and will NOT cover port openings of Chevrolet Bowtie or LT1 heads.
Thanks for looking and check my other stuff.
