351W short block combo...

[scottj]

V-8- you ask how much power is safe with a stock standard 351W block. Not knowing your application I would say for street\strip with that stroke and compression you will be fine. You obviously know a 6.2 rod will "fit" in a 9.5 deck height block. RacerX has a valid point about compression ratio. What octane do you have in Turkey?

Blykins- Re: "such a long rod with such a short stroke". It is the result of "technology trickle-down". For a high-perf/racing application it wouldn't be considered a long rod. A rod/stroke ratio of 1.8:1 or thereabouts is pretty much the standard today.

A quick look at JE Pistons calalog will reveal that the only piston JE stocks for the 3.5 stroke is for a 6.2 rod. Also, that rod/stroke combination uses a 9.2 deck height to keep from having to use a tall, heavy piston. You will also notice that all the standard shelf pistons for the 9.5 deck stroker combinations use a 6.2 rod as well except for one that uses stock rod length. Note that none of them have the pin in the oil ring land.

Brainsboy- I gain nothing by winning against you.

Now why of gods earth would you do this scott?? The answer is for the guy who wants to impress his buddies he has a 433 or 427. At least this excuse has a reason for using this type of a piston. but I cant think of one reason to do it on a 351 with no stroke.

You brought up racing engines. I refer you to a link you can follow to Robert Yates Racing where you will find 178 sets of rods used in Cup racing. They range in length from 6.2" to 6.4". You will also find 67 crankshafts with strokes ranging from 3.24-3.45". They do not use the pistons you say are required for racing engines. You wouldn't belive me so ask them why they use the piston/ring/rod/stroke combinations that they do. Unless you don't consider these racing engines.
