302/347 or 351W

OTreborO · December 19th, 2006, 12:33 PM

OK, I have a 302, and have been thinking about stroking it to a 347.

I have also heard that I would be better just buying a 351W

I thought it was hard to find a 351W, and would all of the electronic crap fuel injection, etc etc hook up to it. I don't think I want to go to carb.

If I do the 302/347, I would like to take it apart myself, and put it back together. Is there some good books or articles on this? I have never torn an engine apart, so I would need a detailed manual. You know, stroking for dummies LOL

Thanks,

Trebor

im not a huge fan of the 347, it changes the angle that the rods travel and it helps wear the motor out earlier, it will last a while, it just wont have the longjevity that a non stroked motor would.

Id go with a 351 personally thats just me, heads will swap, upper intakes will swap, but the lower wont, its a wider block than a 302 and you will need a different dizzy also

A 347 is a perfectly fine reliable engine. Rod ratios mean nothing. A 347 has less of a rod to stroke ratio than a 454 Chevy and that is one of the most reliable engines around. I've had many 347s and not one of them burned a drop of oil or had any premature wear issues.

A 351W is a better choice in my opinion. Only because the block is stronger and the ability to go over 400 cubic inches is there if you decide to do so in the future. Building a 351W will also be cheaper for the average street car because you can use the stock crank and rods and not worry about them failing. The deck height is 1.3 inches taller (9.5 vs. 8.2) but a 351W fits without a problem in a Mustang. You will need different headers and distributor as mentioned above. Many companies make EFI intakes for 351W engines.

I looked at this one site, and they mentioned going with a 331 because of the close relation to the oil-ring on the piston to the pin????

351 blocks are very hard to find......................

there all over the junk yards down here, i counted 15 yesterday in two junk yards

i know... its not hard to find them. it is a little harder to find a roller tho

woody1 · December 19th, 2006, 02:51 PM

351 blocks are dime a dozen, millions produced. There is nothing wrong with the 347, you can get 3 different rod lengths if you subscribe to the "5.400, 1.090CH pistons burn oil" theory. The only thing people forget with the 351 is hood clearance, headers, oil pan etc. If the little extra cost of the 351 does not bother you, thats the way to go.

Justincredible · December 19th, 2006, 05:43 PM

+1 for the 351.

I love mine.

they make a conversion kit, its like 75 bucks or so

OTreborO · December 20th, 2006, 09:42 AM

OK, so am I asking the wrong questions?

I call and ask for a 351W, and I get a long silence.

Should I be more specific?

Thanks,

Trebor

Tell em 351 windsor, ford made a jillion of them, if yu still get silence call them a dumbass.

If you can...the 1971-1974 Windsor blocks were the strongest. They had slightly thicker main webbings.

69fastback · December 20th, 2006, 02:23 PM

69 and 70 351W blocks and cranks are the strongest, because they have a higher iron content. I have a 69 351W shortblock that has never been touched. Everything is standard, and I've tossed around the idea of selling it, but I haven't decided yet.

They knew what I wanted, just didn't have any.

Called several salvage yards. Maybe I will just do the 302 since I already have it

They had higher nickle content though 1974. The '69 & '70 engines only has better heads than the rest.

I meant to say nickel content. I was doing two things at once

I've always heard the 69 and 70 blocks and cranks were better. I did a quick search and the only thing I could get to come up were conversations on other forums like this one http://forums.tccoa.com/showthread.php?p=890520

I'll keep looking.
