Anyone ever run a supercharger on a 351C?

[Bill Wells]

i put a 1960s era paxton supercharger , rebuilt to vr-4 racing specs, on my 351W in my spf .

see pics in my photo gallery .

space limitations are a concern. it is not a cheap addition . the engine should be built specifically to be blower friendly . there is a lot of custom fabricating that has to be done ; bracketry, pulleys, shims, spacers , air ducts, different msd ignition system, rebuilt carb for blower usage, specific pistons for blower friendliness , maybe a different fuel pump yadda yadda yadda . it aint cheap to do . I am sure the same cautions and space limitations apply to your cobra brand and the Cleveland engine.

I would caution anyone doing it that thinks it is a bargain, ie, not expensive and does not have an engine set up for it .

after 3,000 miles my engine blew : top of 3 pistons digested by the rest of the motor, top edges of 3 others gone . valve damage . heckers, parts blew out the exhaust pipe ! autopsy : too much boost, too much compression and wrong engine internals ( the engine in the car was not what it had been represented to be ) .

however, the kick when the pax spooled up was unreal, the sound was like a F16 fighter jet and the eyeball appeal was great .

I replaced the blown engine with a ford racing crate stroker and left the blower off - decided it was not worth the hassle to rebuild the old one to blower specs as summer had just arrived and i wanted to drive and not have the engine out . so i was 'blow to go' in 7 days with a new motor instead .

there are several blower applications for 289s and 302s that are virtual bolt on kits - same with 4.6L mod motors . I am not aware of any 351 bolt on kits - none avail when i did mine . however, some of the 289 kit parts can be used .

for now, i have pleasant paxton memories and wait til i decide to go 'back to the future' and do a repeat - but the right way this time . Good luck . Bill
