351 W HELP!!

[JUICE ONE]

I currently own a 93 hatch w/ a 4 cyl. I'm planning to do a 351 W swap. I found an 84 351 H.O. (E4AE-6015-FA19) out of a truck that was still running and plan on installing new rings, bearings, e7 heads (for higher compression instead of the e5's it came with) and a mild cam. I didnt want to get fancy because it is going to be a daily driver but I still wanted a little more than a stock 5.0 . My question is, does anybody know what size rings to use? I have been looking around and found out that there are two sizes (metric and standard). Also, does anyone know the difference between a 351 H.O. and non H.O. besides a 4-barral carb or is that the difference? Any advice would be of great help.

THANKS!!! :SNSign:

Im using a 85 351W block the HO is a 4 barrel carb the non-HO is 2 barrel. all 302's and 351W's have a standard bore of 4.000" an overbore common when rebuilding an engine will need 4.030" ring set if you go 0.30" over on the boring of the cylinders

THANKS FOR THE INFO. But what I really meant was the size of the stock ring thicknes1/16 or 5/64 and I also believe there is a metric size. Remember, I'm still using the stock standard size pistons.

:OT: My dad has a truck, not sure of what year, but its an explorer, late 80's i think. However it has a 351 with a 4 barrel on i was wondering if it had a 4 bolt main. I could probably get the serial number next time i go home on leave. Also wanted a guestimate on how much power 351's are good for on stock block?

None of the production 351w blocks had 4 bolt mains.
Some have said that the 69 block could be machined for 4 bolt mains due to the increased web thickness (but I have not been able to confirm that personally).
Unless the block in the pickup was swapped out for a pre 75 block, there won't be anything special about it.

Supposedly the 351w blocks can handle 6-700hp (depending on who you ask of course). All will agree however that the the 351w can handle much more power than the 302.

As far as the ring thickness on stock pistons, I don't know. my suggestion would be to decide what brand rings you want to go with, then call their tech line. That is all I can come up with.


Good Luck, and let us know how it goes,
