I am a 32 Ford roadster owner ... and have been for over 30 years ( Yes, mine is a Henry built car ) ... The above photo was taken in Los Angles at the LA Roadster show 2007. I live not too far from you ( South Carolina )

My car was equipped with a BBC 427 with aluminm heads back in the late 60's and early 70's.



This is how it looked at the NSRA Nationals in 1973 ... with the 427/400 Turbo.

If you really want a Big Block ... I suggest you build the frame with the front cross member moved 2 inches forward.



That will give you a good bit more room and will actually help the ride. Original 1932 Ford wheelbase is 106.5 inches stock but with moving the axle forward 2 inches and the rear back 1/2 inch ( to center the tires in the wheel well ) ... you will be at 109 Rootlieb can make a 2 inch longer hood ... no problem ... if you want a hood.



If you trim out the firewall ... and recess it one inch ... that helps also.



A BBC with Aluminum heads, aluminum intake, aluminum water pump and a small gear reduction starter is ONLY about 70 pounds heavier than a all iron SBC.
