Looking for a good shop. Someone that is good with ford engines. A shop with a good reputation that is trust worthy. Anyone heard of Wise performance engineering?
So why offer?
I think you are getting some bad info.
289/302/351 all use a stock 4.00 bore so changing your stroke length won't matter there. Of course you say bore .040 and then say stock pistons so....
Only difference between a 393 and a 408 is the stroke/crank and vastly improved geometry.
Stock rod length on a 351 is 3.500
A 393 would use a 3.850
A 408 uses a 4.000
So a 408 is 4x4...
Which btw naturally aspirated a 408 will get you 550+ at the crank without a lot of effort.
But I'm not helping answer your original question.
I've used Greg's in Shelby 2 times with good results..thatsnthe closest to you ive got.
