Were all US 302s windsors?

[pvillese]

Sorry, this is probably a bit of a noob questions but I don't know much about Ford's history. Some internet searching seems to show that all 302's were Windsors, other than the Boss 302 which I think had a Windsor block with Cleveland heads and some 302s in Australia. I found a guy selling a pre-1980 longblock 302 for $50 which seems like a decent price for a block to use to eventually build a nice motor for my 85 GM.

So question one: were all 302s(at least that I would find in the US) Windsor 302s? Question two: is the block from a pre-80 302 any different than the block in my 85 GM? I'm pretty sure the heads/cam are different since they are not a roller setup but I could always use the stock heads off my car when I got to that point and if I stay with a stock cam, I could use the cam from my car as well.

The body of my car is just in really good shape so over 2 years or so I'd like to gather the parts to build a pretty sweet engine for my GM. Also my engine has been run a few times with no or very little coolant so I'm not sure the engine is in the best shape it could be for an engine with only 75k on it.

Thanks for any info.

The short oversimplified and not techinically correct answer is yes. 221/260/289/302 All Windsor All day.... This is only correct if you call the Ford Small block engine family the "Windsor" engine family. All 302/5.0 blocks had a horizontal fuel pump mounting configuration and had a removable timing chain cover.
All "Cleveland" (335 series small blocks) (351C/351M/400(no M)) had a vertical fuel pump mounting configuration and a cast in timing chain housing. They used a flat stamped steel timing chain housing cover.
The actual answer gets convoluted. 302 engine blocks were not all made in Windsor Ontario Canada. To add additional confusion, 221, 260 and 289s were "Clevelands" by birth (produced in Cleveland Ohio). There were also Mexican 302 blocks (Hecho En Mexico).
The block from your pre-80 302 is different in that it uses a rope style rear crank seal. It is otherwise functionally equal. The odds that your 1985 block was cast for roller rockers is near zero.

Mercracer- didn't they change the internal crankshaft balance in roughly 1982 from 28oz to 52?oz... and as such, if he's planning to use the 302 short block as it sits, it won't work?

A new 28 oz AOD flexplate is almost free.... ALL 351W motors were 28 oz and plenty of 302s had AODs before 82 and the balance change to 50 oz.

crank balance doesnt mean anything to the block casting, just make sure your flexplate and balancer match the crank's balance.

Thanks for the responses guys.

mercracer - based on your comment, if my engine happened to die before I got the new one rebuilt how I want it, could I actually just put the intake and throttle body from my original engine and the right flexplate and balancer on this one and drop it in my car? If that's the case its worth to just pick up and have sitting in the garage for now.

Can the rope style crank seal be replaced with a different type when I rebuild it? I thought that I've read that the rope style are pretty problematic.

Thanks again for the info. The only other ford I've owned was my 84 mustang which sadly I never got around to modifying or even researching into what I could do to it. I had built a pretty sweet k-car shadow that was a total sleeper but still wasn't as much fun as the mustang.

I see no reason why you could not.

Would I be making a mistake buying a non-roller engine? Are all 86+ 302s roller blocks? Based on some of the other threads on here it sounds like there are some good stock cams in other engines that are roller cams. Although at that point I'll probably be going to a carb or aftermarket EFI(I'm guessing the CFI cannot handle too much of a change) so I probably might as well just build a 351.
