I have a 302 Windsor and Im wanting to put on some cleveland 2V or modified heads on my 302. Is there a web site that has pistons and related parts for what I would need for this conversion?
Here's what you'd need: Boss 302 pistons (cleveland valve layout with a 1.55 pin height), Boss 302 rods to use with the 1.55 pin height pistons ( 5.155" long) Cleveland heads with quench chambers ( to keep the compression up where it needs to be) choice here is 70-71 4 bbl heads or a set of the later "Aussie" 2 bbl heads (these come up on ebay all the time)When you get these heads, they'll need modification to alter the coolant path to route it out thru the intake rather than back into the block (intake face drilled at the end and block port beneath this plugged) Lastly you'll need either an orginal Boss 302 intake or a "Street Boss" or "Track Boss" intake made by a company in Ft. Smith Ar. twenty years back (ebay item too) I don't recall the mfg. name offhand for this one. When you finnaly get it together, you'll have an engine more easily made using aftermarket Windsor style heads at half the price. In short, you will have to REALLY will want this style engine to do it for the time and effort and money it'll cost.
the company that made the intakes was B&A perofrmance, and then later bush performance. price motorsports has intake adaptors to use a windsor intake with cleveland heads. one thing you forgot D. was the headers. they are going to have to be custom built for a capri.

i've been told that Bush performance is still around and still makes the intakes do a search on the net and you should be able to find contact info. also original boss intakes are bringing super big money about $400 or so, so they aren't hugely expensive. D.Hearne is correct that you need the 5.155" rods but you don't need original boss 302 pieces, the 289 uses the same rods and in fact the boss 302 rods were just updated hi-po 289 castings with bigger rod bolts for the most part. there are also several aftermarket companies that make a 5.155 rod like Eagle, etc. and TRW still makes the boss 302 piston, or at least they did last time i checked anyway. you also have the option of using aftermarket aluminum cleveland heads these days, CHI, E'brock, Blue Thunder and MPG head services all have them. and lastly, i've heard that E'brock is going to start making an intake especially for the "clevor" style engines either this year or early next year. headers will still be a pain to find but i think you can use early mustang headers in a fox body just not the other way around, though you may have to some modifications, not sure what if any though.
From what I remember about MY BOSS 302 the pistons would not interchange with a Cleveland motor because the BOSS was a pent-roof and the 'c' was not. But if he needs some BOSS 302 rods.....I have a set. They are not cheap. I may put them in my 289.
Everything else I'm in 100% agreement with. Just get a 351c.
The rods were forged.

I remember the BOSS 302 came before the 351'c'. 1969/1970. And do you have a side by side picture with casting numbers visible of a BOSS-302 and 4 barrell 'c' head to show your point?the only difference between the boss 302 piston and the 351c piston is the pin height. remember that the boss 302 used a slightly modified form of the 351c 4v head.
Neither the C or B had pentroof chambers.
The Boss used slightly modded Cleveland heads.
Much will interchange, or at least was built on the same foundation.
Think of the Boss as a hybrid between 289/302 and 351c.
That's all it was...

For giggles, here is the original "Boss 302" head -circa 68-, before they called it Boss, of course.
Edit:
Riddle me this...
Which intake flange is the B302?
Which is the Cleveland?
Top or bottom...
