well me and a buddy are trying to put hooker longtubes on and are about to burn the thing down. we got the factory stuff out no problem but cant get the new stuff in. i have looked at all the write ups and instructions and nothing is helping. im thinking about dropping the motor out the bottom at this point, installing them, and puting it back in. has anybody else done it this way??

 

If you have everythinout of the way the passenger side will go in through the top take the valve covers off disconect the stearin your good just play with it your this far so it only get easier

 

try to get it, as high as possible and install it from the bottom...mine was easy from the bottom...but then again i have a lift....the hardest part for me was taking off the old exhaust manifolds

 

the old ones were so easy it wasnt funny. im pullin the motor rightnow have one bolt left

 

so dropping the motor was way easier than what we were doing before. if i had to do it again thats how i would do it.

 

i have never had a problem installing them through the bottom. remove starter, oil dipstick, and plugs and wires for the passenger side and oil filter, plugs and wires for the driver side. like others have said, taking the old stuff off was the hardest part.

 

i dont know y it was so easy to take the old stuff off. but it was a joke. i have a question though are all he headers for our cars d ports cause i just noticed that these arent. i know they will go one cause a buddy had them on his. possible from a third gen???

 

you have to put them in practically vertical.

 

+1 for the above statement!

 

all LT1 long tubes i have seen are a standard port. works out nice because they will work with the LT1 d-port heads and standard sbc heads if you ever want to drop in a nasty SBC.

 

did not know that

 

I seen a pic of some jethots that had the d ports, but my older jethots has the standard ports. Its the only header I've seen with them. Heres the pic.

 

good info^^^^^^
