Can I ask you about the 400 block??. Are you sure it is a good core??. Those are getting kind of rare. Especially on a 400 you don't want a bore and hone without the pistons in the hands of the machine shop and do not do that without torque plates.A extra step is to sonic check the bores because some are casted as thin wall blocks.You need to know you have a sound bottom end before you spend money on the top haft,don't you??. Don't you need to know you have a flat deck before you plot out heads and SCR's??. Here again the 400's trait isn't to have a used engine with flat decks.
I did see you said a factory 400.but I am not sire what you mean in saying that.Still most of what I posted still applies even if it is a brand new casting.
BTW-have you called Brodix and asked them how much to port good used clean castings??. I would bet money they have a killer porting program that would be hard to match. Even if you have to pay more,you get tons more back in return.

when building a 400sbc with a 64cc head use a -18cc dished piston.
Like a KB147 piston (5.7" rod length.)

|vinniekq2||phone the shop before you go,not all or many shops have a flow bench|
|11-28-2012 06:30 PM|
|gamedawg03||Thanks for the info im going to take them to my machine shop and let him flow bench them|
|11-28-2012 05:40 PM|
get your heads on a flow bench.2 reasons.if the flow numbers are good then you know your horse power potential,therefore easier to pick the matching parts,second reason,lots of heads are weak on the exhaust side, so they need porting on the exhaust side or you can compensate slightly with a split duration cam.
If you dont measure the flow and build the engine,later if you are not happy,you have no information to work with.That car will dip into the 11s with those heads stock out of the box.The quality job you do depends on the details you look after,,,,have fun with that car.I worked on a friends monte carlo and we made it go 14.1s with a near stock 400 and 2.73 gears. It also got decent mileage.

|gamedawg03||Yeah the heads are 64 cc yeah im new to the game i wanna learn as much as i can how and what do i need to cean up on the heads and scale of 1 to 10 how difficult is it for a amateur|
|11-28-2012 02:56 PM|
Ya they are ok. You can make the Vic JR more OK with some sweetening.
Clean up port match and a spacer.
you don;t seem like a hard core racer. I would not go with a 12:1 cr.
Keep it pump gas compatible and work on other areas for real street/strip gains.
less than 11:1 cr measured.
What is the IK 200 chamber volume. 64 70 (measured)
You want accurate real specs to build a motor.

|gamedawg03||I have a victor junior intake and a demon 750dp would they work ok for this setup|
|11-28-2012 02:36 PM|
The IK 200's don't need that much work to wake them up.
Pretty much a clean up. You can consider doing that yourself.
They don't need big re-shaping. Just clean up and contour whats there.
Do not shop or chase flow bench numbers..
These heads work very well with a general but complete clean up.
The dart 215 head is not a trade up. Its more of a trade over.
You will get more of what you want by cleaning up the Brodix heads and getting this roller
and matching up , sweetening up a intake and HP carb for it.

Get some Air Lift Air bags (drag bags) and control arm relocations brackets and a drive shaft loop for your monte. The stock GM posi will bust.. Get a NEW Auburn or A NEW Eatons posi for it.
and some sticky tires .. ET street or slicks or Drag Radials. 26" to 27" tall.
