408 or 418
I am in the middle of researching for parts on my L92/L76 build and wanted some opinions on things.
Using a 6.0 iron block
First off would be I plan on a totally N/A motor that being said what would be a better route a 408 or 418 i know there really isn't a whole lot of difference there but any little bit helps.
Also I plan to have the l92 heads milled to 65cc chambers will i run into any Piston to head clearance issues on a 418 I will have the block decked some.
Another question is I really only planned on having a little exhaust port work done on the heads them self so would they be enough to even supply a 418.
