64 Post sums it up pretty good. What do you want out of this motor. Aluminum block and heads, then you are in the small block iron motor weight. A lot less weight on the front end. Cast iron hemi is heavy. Aluminum if hurt can be fixed easier. Most of the Big Builders use the Aluminum Head and Blocks. The new MP iron stuff is a lot better than the old stuff. FHO-Tim Banning,John Arruzza and plenty of other are good builders and generally a good bang for the buck. Some are backed up with orders and it might take a while to get your build back. You live in Canada on the east coast. Banning is 35 minute east of Toronto North on Hwy 28 out of Port Hope in Bewdley Ontario.
