I decided to have a look what could be done with all of the ideas floating around here on engine mods at the moment 
This engine uses the following:
3TC 89mm Pistons (TBC waether this is an option)
5.7" Small Journal SBC Rods with offset ground crank to get 84.5mm Stroke.
Ported heads with Standard inlets and 30mm Exhaust valves.
12:1 CR
Kelford 207-B Cams
2500CFM ITB's (4AGE 20v TB's drop by about 10HP and 6-8lb ft)
Good exhaust.
Final result:
458BHP@7500
399LB FT@5000
Just thought some people might be intrested in what can be done NA as most stuff on here seems to be focused to FI engines.
