Let me tell you my JBL experience. When my chassis arrived, we started to open the crate, holding the frame to the bottom of the crate were grade 8 socket head capscrews!Talk about overkill. These boys are first class. Don't let the lack of cars piled up all over the place at their shop bother you, they are all about QUALITY not quantity. and yes the chassis can accept a big block. Daves Coupe has a 4.6 Cobra Mod moter in it, so any big block will fit.
