which 347 stroker kit?

Punter, I just can't envision a $599 stroker kit as being worth your time.

Without bearings and rings, prices start at around $800. This is for a decent SCAT or Eagle reciprocating assembly with forged pistons.

If budget is an issue, you'll be fine with the cast crank and I-beam rods. They will outlive the stock block as far as HP capacity (which is around 550-600).

Engine builders say the 4340 forged cranks and H-beam rods are proven at 1000 hp. This sounds like overkill for what you need.

A hidden cost is the new balancer and flywheel. Those must be changed to 28 oz. with a stroker kit, whereas stock is 50 oz. Add about $300 (non-sfi) or $500 (SFI) for these items. Also, the balancing cost is higher for a stroker. I don't want to discourage you, but just to help you make good decisions.

My car is like yours...it's for street and occasional strip. I'm currently building a 331 and decided not to go with a 347.

Some of you own a 347 that's working well and that's great...all I can say is that for every satisfied 347 owner, there's an unhappy 347 owner. I didn't want to take my chances and be in that second group.
