Hi guys, finally getting a chance to build up my 400BB that i have had forever, was foolish and young and listened to the advice of others and tore it down with no budget to rebuild it, now as it sits I have a 400BB , nothing real special just a '78 (date code 10-4-78) block stock bore
stock (to my knowledge) 906 heads
and i was told this is a forged steel 383 crank
the red stuff you see is HD bearing grease to protect the journals
can anyone confirm this is a forged steel crank ?
Also with this crank does my stock 400 rods and pistons have to get balanced as a whole ?
What kind of crank damper do i need to run ? one for internal balance or external ?
got a bone stock '67 727 that i am getting tomorrow from a guy here local, worked when pulled, I will still go through it before i bolt it all up together. What kind of flex plate should i use ? I can't imagine this thing making gobs enough torque to break a stock one in stock form, also does a slant flex plate fit a BB 6 bolt crank ?
I will need a cam for this and i plan on milling the heads to raise compression, is there any way to figure out how much to whack off to bring the CR up ?
I have been hearing good things about a few summit cams,
Summit Racing® Camshafts SUM-6400
Camshaft, 1-Bolt, Hydraulic Flat Tappet, Advertised Duration 288/298, Lift .444/.466,
and Summit Racing® Camshafts SUM-6401
Camshaft, 1-Bolt, Hydraulic Flat Tappet, Advertised Duration 298/303, Lift .466/.488
Any mopar cam recommendations for helping wake the 400 up ?
How much can i mill the heads before i need to worry about adjustable rockers ?
I know alot of questions, but i come from boosted slant land (max'ed at 18lbs of boost before i lost the head gasket all stock engine with a good tune on the carb) and really haven't dabbled to much in big blocks, i will eventually have an all forged as close to stock, (bore/stroke) and run a pair of holset hx-35 turbos, but for now i just need to get it running, so its gonna be bearings, rings and seals, but really looking at cam and head recommendations from those in the know
P.s
