Mike, Hal,

Thanks for the posts, and the information on the RDI alloy block, and your engine details!
I had a look on the RDI website and they claim a weight saving of 60Ib compared to a cast iron windsor block, which all helps, pending my budget!

With the 427 stroker you have certainly got a good cruising top gear with the TKO at 0.82, but I guess if you reduce the final drive ratio say to a 3.55 or 3.70 you will make the lower gear ratios closer together, and maybe not gain much more acceleration.
