Oh ok, I guess I didn't consider the lnf fitting better lol it makes sense though. Seems like a lot of work though. Would using the lnf header have any benefits other than aesthetic?

the intake runners on the lnf intake manifold are around 20% larger in diameter unfortunatly it is hard to make use of that without a port job on the cylinder head

Oil Banjo Washers 12626102
Coolant Banjo Washers 12626102
Coolant Feed Banjo Bolt 11561875

Also the hole where the oil return feeds into the block is a hair biger then 3/4" acording to a guy who did this swap on jbody.org 3/4 hole will alow the tube to slide in but not with the o-ring

And just for referance the studs and bolts for the O2 housing, and downpipe are M10X1.5

Drilled and welded the bung for the wideband today

Sealed the welds with some ultra high temp exhaust sealer from versachem Nasty Stuff, if you ever use this stuff do not let it get on your skin It will burn the S#it out of you

And here is a wood pattern for the Flange the undrilled holes will be the studs for the LNF intake manifold. Now that we have verified we can proceed the way we planned, the Aluminum flange will be ordered next payday

The treadstone kit is nice. Affordable and good quality im happy with mine. So how long till you start putting it on the car?

Axelthered05

well im looking at around May 20th for the build day however I jumped the gun a little and already installed the one degree colder plugs along with a few test fits of the intake manifold

Dart_SI

Axelthered05

Just out of curiosity...

Why not use aftermarket(or custom) parts instead of the stock stuff? Like Downpipe, Intake etc...

Axelthered05

iTrader: (9)

charge pipes, intercooler, and eventually the intake will all be treadstone the down pipe will stay cause I dont all the noise of a high flow or catless

Can't wait to test fit this on the car

Update Time
ok since Im going with the flange setup the flange is installed first

a test fit reveled that one of the nubs of the intake manifold was hiting one of the alt wires

so that nub went bye bye

so here it is instaled


oh just for referance both with and without the flange the intake manifold is in the way of the oil filter and the intake manifold will need to be removed to take the oil filter cap off and with this setup you can not use the Stock, LNF, LSJ dipstick. Im going to have to come up with a solution to that...

IonNinja

are the flange to head bolts level with the flange surface or do they poke some? it doesn't look like the manifold is sealing against the flange at those points

Axelthered05

iTrader: (9)

the flange to head bolts are not flush with the flange I had to mill out a bit of the top 3 bolt holes of the LNF intake manifold like so only the heads of the bolts extend about an 1/8th of an inch beyond the flange
Red is cylinder head
Green is flange
Blue is manifold
Yellow are bolts

Axelthered05

I just looked at the pictures I posted and in the picture with the flange conected to the manifold the bolts are not screwed in all the way so thats why it looks messed up, tightened down they only come out about 1/8th of an inch
here is a picture of the bottom side of the top 3 manifold bolt holes ware I milled away to make up for that 1/8 inch of remaning flange to head bolt
