Jim,
I am located in Michigan, about an hour north of RCR. Where are you? Using the 5.2 Aluminator engine and Graziano transaxle. Going to start build log soon.
I was thinking about ordering those same engine mounts, but wondering the same thing on bolt sizing.
Would be happy to compare notes and plans as we are planning to put more time in on the build over the winter. Current open questions are around part options for the engine including:
1) Exhaust Headers - interested in Ceramic coated - buy BBK / other coated headers or build and have JET-Hot coated
2) Exhaust System/Routing - planning on using Cats
3) Fuel System - planning on the fuel tank modification and using a Holly hydramat or similar system
