I have a bet with a friend about hp potential for a 235. Obviously the stock engine is held back signifigantly by the design of the head and combustion chamber. However I feel there is potential for serious power hidden in the 235.
What I'm working on is a bed plate, and a crossflow 12 port head for the 235. It will probobly be similar in design to the wayne 12 port but use modern style rockers, wedge shaped combustion chamber, larger valves and aluminum as opposed to cast iron.
There are reports (unconfirmed) of people getting +300 hp from highly modified stock components and even more from the rare 12 port or chopped up sbc head applications, and forced induction.
I believe with the right combination of components +550 NA hp is possible.
***No I'm not crazy, I realize thats a huge number for a stovebolt. Please limit your responses to constructive and informative posts rather than just yelling "your crazy" or "that will never happen".
--Planned component overview--
Crank - stock forged 235 (balanced rotating assembly)
Rods - 261 job master (or custom)
Camshaft - custom grind hydrolic or roller
Block modified for 1 piece rear main seal and bed plate
Dry sump oil pump
Electric fuel pump
Ignition TBD
12 port cross flow aluminum head (cc's and valve sizes TBD)
Custom bed plate and oil pan
Lightweight pistons with 1mm, 1mm, 2mm low tension rings
I know it will be a ton of work just to design the parts, but I have lots of free time and the desire to see it through. So please share whatever information you might have as any help I can get will be greatly appreciated.
