I'm building a mild-performance 327(as a heads-up, I did check the Modifications Forum and noted the con rods flyer - but could not determine if it was written exclusively for Packard i8's or if it was written generally across all types of engines. Also, there's very little posting activity over there - so wanted to post here where I'd get better visibility -thanks).

I want to know if the stock rods I have (I'll be getting them magnafluxed ASAP are suitable to keep or if I should get something custom or off the shelf for a HiPo application). FYI - the engine spun freely and was relatively low mileage when I got it, maybe 100k miles on block.

here's the build;
327 Thunderbolt block - maintaining stock bore
288 head which i'll be doing mild port and polish (let's assume no decking required)
VS57 McCulloch supercharger to triple Stromberg 97's on custom intake with custom runner lengths
I will probably open-up the valve size a bit and use custom or GMC truck valves
my hope is to leave the crank stock, but if any balancing or lightening is required, i'll do that.
i'm hoping for about 250HP out of this engine

The car is going to be used for long distance 1,000 mile open road rallyes, where sustained speeds of 80+ mph may be common.

...so again, the question is, do you think the stock rods are up to task, or should i go the custom or HiPo route?

thanks so much. -Wes
