    using a 390 or 428 crank with stock 352 rods ??

     



    Ive got a 352 block bored .080 over with brand new pistons and stock rods for that motor.Brand new stock ford heads for that as well.I dont have the numbers here with me but i know its an early/mid 60's block ( if that makes a difference here) WE also have a 488 lift cam for this . Now....I also have the original crank that was out of this that looks pretty good but has not been checked yet.The freshly bored block with new bearings in it is on the stand and ready to go.This is going into a 65 fairlane that has a rebuilt C-6 with man valve body.I think for the first run we are going to try a 456 gear. here is the question .....can we use a larger crank (390 or 428 ) with these new stock rods for the 352 block?

    Hey aml396.

    The 352 stroke is 3.50"

    The 390 stroke is 3.78"

    The 428 stroke is 3.98"

    Using the 390 or 428 crank would cause the 352 pistons/rods to protrude past the deck of the block.

    What you need to do is add up the measurements of all components you will use (called the "stack") and fit them into the block deck height you have to work with. Problem is, the 352 piston compression height and connecting rod lengths are "one-off" for the 352 and won't work with other FE components to make a larger CID combination, at least not using stock dimension parts.

    Cheapest way to get more cubes would be to install +0.030" 390 pistons, 390 rods and 390 crank.
    Or, you could use 410 +0.030" pistons, 390 rods and 3.98" crank from 410/428 to make a 417. These parts are available on ebay.

    What is it that you plan to do with the car?
