If it is the original engine, get your VIN (you can see it on a tag inside
the windshield, it should also be on your insurance policy paperwork) and go
It will tell you some details, including engine, of your car.
Which is why I asked the year & gave the firing order. I can see the
difference between a 302 & a 351W w/o measuring or checking the firing
order just by casual glance, as many here can.
The Clevelands & Modifieds are so radically different(aside from the
blue paint) from the Windsors, it's like the difference between a SBC &
a 409. Nobody should take one for the other.
mistakenly placed my resp. to you rather than to OP. Not knowing his
mechanical expertise, tho't I'd throw that in for him.
BTW, I sincerely applaud your ability to distinguish between 302's and
351 W's, something I never learned. I did enjoy selling the W's over the
years as they seemed to just run & run w/o comebacks.
Another thing, please. Am I remembering right that a mechanic once
installed a 302 cam he had in stock in a 351W of mine, and just repositioned
the dist wires so it had the 302 firing order? Maybe an early '70's model,
a nice 4-dr. I accepted on trade with a lumpety racing cam.
Thx in advance for the info. s
Yup, the 302 is just obviously more cramped for space when you've seen
enough of them.
Yes, the cams are interchangeable, with the change at the distributor.
Ford turned this all upside-down in 1982 when they turned to their own
parts bins to source a 1973 351W marine profile cam for the first 5.0 HO.
The same or similar camshaft was used for years in the MerCruiser, OMC,
& Volvo Penta outdrive(I/O) 302's & 351's - 188hp(302 2bbl) through
255hp(351 4bbl) with several combinations / hp's in between. Several
forward-rotation(left-hand prop) inboard builders used them too -
Crusader, Indmar, Pleasurecraft(mostly reverse rotation, though), Thermo
Electron, Palmer, there were 40 or 50 back then.
The 351 order takes some load off of the front of the crank & #1
main(the 1-5 combination) and instead puts it closer to the flywheel &
#5 main with the 4-8 combo.
The end of the intake manifold (the part that seals against the block - not
against the head) on the 351 is about 6 inches wide... on the 302 it is
about 4 inches wide.... This dimension is as measured agains the block - not
at the upper surface.
The bottom front surface of the intake manifold is almost flush with the
distributor hole in the block on 221-260-289-302 and 5.0W engines. The 351W
has about 1 inch more material above the distributor hole at the same place,
