Newbie 351 swap questions, I checked old posts w/ no answers

You guys are the best, you really are helping me out, I couldn't wait to get out of work tonight to see if anyone had answered my questions, I truly apreciate your time and information, and I will put it to good use. Thank you again for your help.

Just another quick question, does anyone make aftermarket fuel rails for 351W? looks like I'd have to buy a 5.0 fuel rail and modify it to fit the wider 351?

how well do 351W respond to supercharging, I heard that they were able to take more boost than a stock 5.0 and that they made a lot more power with the same boost because of the larger stroke/ displacement, My question is: how much can a 351W with a stock lower end take, can it handle 400-500hp? Or should I keep my goal Hp below 400hp if I want a car reliable enough to last more than a few runs.

The “M”, by the way, does not stand for anything. Ford only used the “M” designation to distinguish it from the 351 W (Windsor) and the now discontinued 351C (Cleveland). The “M” designation has now become know to mean “modified” or “Michigan”, even though the 351M was produced at both the Cleveland foundry and Michigan casting

The engineers at Ford took the basic 351C block and modified it to power a whole new generation of environmentally-friendly cars and trucks. To start, Ford changed the transmission bell-housing pattern to match that of the larger 429/460 engines. This would allow Ford to continue putting the larger, heavy-duty 460 C6 transmissions with the new 400 engines. Ford also enlarged the main journal diameter from 2.75 inches to 3.0 inches allowing for a greater bearing wear area. The crankshaft stroke was also increased from 3.5 inches to 4.0 inches for a 50 cubic inch increase in engine displacement and greater low-end torque. Finally, the deck height was increased 1.09 inches in order to accommodate the 400s larger stroke. enter.

I have modified a fuel rail for a 351 it took 10 minutes and worked great. We had 24#injectors on a 393 stroker making 400+RWHP.
