1)When buying the pistons on Eagles site they ask your engine size your building that would be a 383 but....from my understanding there is no boring involved other than cleaning which is like 5 thousands barley noticeable so would you buy pistons for a 350 or a 383?
positioned differently in the piston to keep from pushing it out the top of the bore.
Think about it this way; if your stock piston comes within .065" of the cylinder head and you use a crank with .270" more stroke (.135" up, .135" down)
That piston is going to have a problem when it impacts the head.
I hope that makes sense.
Also, .005" (or .030" in this case) may seem insignificant, but it's a HUGE deal when trying to get rings to seal in a cylinder. The last thing you want is a piston jiggling
around in there destroying your walls and tuning itself into shrapnel.
Can you build a 377 (stock bore, 3.75 stroke)? Sure you can.
But you're still going to be running pistons designed for a 3.75 stroke.
350 Stock bore 3.48 (stock) stroke
377 Stock bore, 3.75" stroke
383 Stock +.030" bore, 3.75" stroke
