Im out swapping intakes(BBK) on my car (00 Trans am). And the ****** wont sit right on the heads. You can line the bolt holes up and there is about a 1/8" gap or so between the intake and the heads, and you can wobble the intake back and forth... Any ideas??? i need help fast, im out in the garage as we speak... Thanks

 

have the heads been milled at all? Not really much anyone can do for you.. there is no spacer that will fix this that I know of

 

 

as far as i kno, no the heads havent been milled. the whole car was stock when i bought it, straight down to the exhaust

 

i put some grease on my coolant lines to see if they were touching the intake, and it seems to be hitting them pretty good.... how can i fix this?

 

yeah, the non-ls6 motors had a coolant line that connected the front and rear head steam vents. your best bet might be to upgrade to the LS6 system where the rears are blocked off.

 

get the coolant block offs that you need when going from a LS1 intake to the LS6 intake

 

Get the block off plugs off a newer motor like on the trucks that don't allow water to transfer from the back of the heads to the front. Then just do the crossover in the front. That's how the new trucks are, it should be ok for your car.

 

lol @ 3 posts in 1 minute on getting the block off plugs

 

I have a modified crossover, its what you need.
If you want it let me know.

 

id love to have it, but i gotta have this car outta the garage by tomorrow :-/. Anyway i can get plugs from a hardware store? i replaced the plenum bolts with shallow head, and that helped the front but its still hittin the rear coolant line. imma pull em off and see waht im dealing with. Thanks for the fast replies guys!

 

nope... they're fancy bolt-in plugs. you might be able to get them in stock a local stealership

 

Heres my plan since i gotta have this done. Im going to cut the coolant lines where the red lines are, then connect a hi-temp rubber hose between the cut ends with clamps. think this will be ok? I dont see a problem with it, that way the holes will be "plugged"

 

Search for this man... You can modify it yourself. There are plenty of threads floating around about it.

I don't advise nor would I do this......

 

you are still going want the fronts to be functional... search around, it's been done.

 

Your best bet is too double flare the ends of those tubes if you cut them. That way you will not get any leaks. You may be able to get away with a couple clamps on some heater hose but I personally would not run that in my car forever. More of a temp fix until you get heads, then do it right. What you are suggesting has been done before without problems. I personally grinded the fins on the bottem of my lS6 until it fit right. Not sure if that is possible with a BBK but the coolant crossover tubes that cool the back of the heads especially around CYL 7 is a added bonus for me since I run a 98 block and spin it too the moon. Keep us updated how it turns out.

 

get some low profile bolts for the valley cover ,the stock ones mite be holding the intake up.

 

did you read the directions

 

Also you will need the button head valley cover bolts. they are M8x1.25 x 30 you need 11. I know Ace hardware carries them.
