I just joined the forum because im building a diablo 6.0 with a 1000 HP twin turbo LS1! I bought a partially built NAERC frame last week. Im working on finishing it and making structural improvements to handle power. I own a machine shop that makes custom car and paintball gun parts.
If anyone needs the NAERC spec A arms bushing made (rubber, nylon and steel) I can make them for you on my cnc lathe for a decent price.
shoot me a pm
