I saw on Molnars website a listing for a 4.65 crank that they say fits the stock 400 block
anyone using this or know of anyone using this or built one?
I see 4.75s listed by other vendors and at one time thought 5" was an option
price is the same as their other cranks too (maybe the 5" is custom and not in the same)
401-4650RC6F is the part #
Anyone have a 5" stroke build? is that only possible with a tall deck aftermarket block?
my thought is if crank prices are the same why not put the bigger arm in now and save bores for later....
email response:
The crank should work fine in your stock block. I checked with Mr. Molnar to be sure and he said that as far as he knows these cranks have all been going into stock blocks and he has not heard of any problems.
Sorry but I can not recommend any particular builder.
That crank is meant to be used with any of the Molnar Technologies big block Chevy rods listed on this page:

You need to match the crank stroke and rod length with the piston you want to use. Most of the pistons for this combo have to be made as customs so you have a few different choices in rods.
