|  351w or 347 stroker? which is better? Given the choice, which combo would be better for street,strip use, a stock 351w or a 347 stroker? I have both a 351w complete motor and a 302 complete motor that would need a stroker kit. They are both non-roller blocks. Would there be any benefit to doing a stroker 302 when i have a 351w. (I would need all the conversion items for the 351 to fox body). What do you all think? Decisions, decisions...

| Why not just stroke the 351w to a 408? The money you would spend stroking the 302 could be used to stroke the 351. It all comes back to how much $$$ you have to spend.

| 302-351w I've thrown that one around myself. If You stroke the 302, you loose engine life. If you don't stroke the 351w, it lasts longer. For me the 351W for street use is my choice. For the strip, a stroked 351w would be turning faster ET's for a few bucks more...concidering it all costs alot $$$$ in any case. |

| Dollar wise I'd go with a 392ci stroker. If I remember right a 392 is a 3.85" storke crank, 351w rods and 302 pistons. FRPP sells the crank (I think it's like $500?) and if you can't or don't want to use the 302 pistons you have, stock type pistons should be cheaper than the stroker ones. IMHO Brian Where is Clawson,MI

| i have a 347, and to tell you the truth i could have built a 351 for the same exact price. (a stroker) check out ebay, there are companys on there with ebay "stores" and they have everything for a stroker, (i would piece one together) forged 347-408 cranks for 300.00 brand new. you will save probably 200.00 on each thing you buy if you go through ebay. i would only buy from the stores though and from people. |

| I would go with the 351 just for longevity. I'm sure the horsepower numbers are close to being the same and the 351 is almost garenteed to last longer.

| I think what WADS56 was trying to say is that if both engines had same compression,heads,intake,cam,induction and exhaust etc. that the 347 would still make more power than the 351. Actually, a 347 really has 350 cubic inches of displacement but they didn't want to advertise it as a "350"

| I am not trying to argue at all. I'm just curious cause I don't understand why one would make more power than the there. Even being a 350 as you say I still don't understand. If every part of the setup thats affects flow or power production on both motors (compression, heads, cam, ...etc), why will one make more power than the other.

 A 347 which uses a smaller crank journal than a 351 will free up a few ponies right there. Also, the .030 over bore on the 347 will hep the intake flow beter then the 351 with the standerd bore. This will not make huge power gains over the 351, but it will make more And as far as the 351 lasting longer....? I don't agree with that either. If it was a 600hp motor then yes, a 351 is a much stronger block. But if this was a 350-400hp motor, they will last the same.Wade | |
