as i said before my post was deleted, i cant believe you lot are being so bloody picky over 1 cubic inch!

most manufacturer's if not all, round up to the next cubic inch, or metric unit anyway...

Well my theory is quite simple, if its a 351 crank, then its a 351, who gives a s**t if its 20, 40 or 60 thou bored.... its still a 351, not a 366 or anything else, unless its offset ground (yes boring increases displacement but who really gives a s**t, hell you could even grind 3cc out of the heads, then you've got a 375, but it doesnt mean it will go any harder than a std 351)

On the stroker subject, use a std bore block, as the pistons to suit a 393 are very short and exert a lot of sideways load and wear the thinner bores quicker.
When my brother got the pistons for his 393 and showed me, i laughed at them, they are shorter than most pistons found in 4cyl buzz boxes. The SCAT cranks and rods look good though

thankyou jamie!
