GOTHALOSISM Posted September 18, 2010 Share Posted September 18, 2010 I finally got the JTR mounts done now I cant seem to get the engine installed correctly. I am using the stock exhaust manifolds and for some reason they keep hitting the rails. Do I need to get center dump manifolds or are the stock ones usable?

deja Posted September 18, 2010 Share Posted September 18, 2010 (edited) You can't use the stock exhaust manifolds. Get some block hugger headers. LT1 use a different exhaust "D" port in the head than the old school Chevys so those center manifolds are not what you want either. JTR sells a Sanderson (Dat-402C DP)header that most of us are using. That C in the part number is for ceramic coating. It will make the header last longer and help transfer heat away from the engine bay too but it is another $100. Some have found headers on EBay that work too. Just make sure you get LT1 specific headers. Edited September 18, 2010 by deja Quote Link to comment Share on other sites More sharing options...

GOTHALOSISM Posted September 20, 2010 Author Share Posted September 20, 2010 I found a guy that has some hooker shorties that I need help with. This is his message to me.. "I have a set of hooker ceramic coated shorties (SBC Gen 1 style) 1 5/8" primary's that i currently have on my LT1 im parting out. How's $100 shipped sound?" Will the work? If so I am going to grab them ASAP!!! Quote Link to comment Share on other sites More sharing options...
deja Posted September 20, 2010 Share Posted September 20, 2010 I can't say for sure but the price is right. I think there is a difference between shorty and block hugger, you need block hugger. I don't thing Hooker makes a block hugger any more if they ever did. Also ask him if they are "D" ports which is what the LT1 has. Just because thye would bolt on doen't mean the will work properly. Maybe some one here has used Hookers on the LT1, try searching. I found a guy that has some hooker shorties that I need help with. This is his message to me..

GOTHALOSISM Posted September 20, 2010 Author Share Posted September 20, 2010 Thats what i am doing, he has had them on his lt1 for a few years with no issues. Quote Link to comment Share on other sites More sharing options...
deja Posted September 20, 2010 Share Posted September 20, 2010 Yeah they will bolt on but old school SBC ports were square, LT1s are D shaped. Trust me I learn that lesson on my AMX back in the day. I used 69 headers cause I got a deal not knowing the 70 AMX had changed the ports to a dogleg shape. The car ran much worse with those headers than it did with the stock manifolds. Also did he run these in a Datsun? Thats what i am doing, he has had them on his lt1 for a few years with no issues. Quote Link to comment Share on other sites More sharing options...
kamikaZeS30 Posted September 20, 2010 Share Posted September 20, 2010 (edited) Hooker made headers specifically for the Datsun Z swap, they're discontinued now. They still make block-huggers, which will work (D-ports). They're like $230, though. http://www.sfxperformance.com/parts/HOO2100HKR.htm Edited September 20, 2010 by kamikaZeS30 Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted September 20, 2010 Author Share Posted September 20, 2010 Ok thanks the ones he has are the 2460hkr so that makes it the JTR ones after all. It would have been nice to have caramic coated ones for $100 shipped though Quote Link to comment Share on other sites More sharing options...
deja Posted September 20, 2010 Share Posted September 20, 2010 Not for the LT1. check. You'll see they are for oval ports, not D ports. They do NOT look like block huggers and I wonder if they would really fit. What makes you think they are the JTR ones?

GOTHALOSISM Posted October 21, 2010 Author Share Posted October 21, 2010 I ended up getting the JTR ones, really easy to install. Only issue I have now is I have to relocate the knock sensors. Oh also I have to get it running. Tried last night and noticed the oil filter was leaking real bad. Quote Link to comment Share on other sites More sharing options...
deja Posted October 21, 2010 Share Posted October 21, 2010 I moved my knock sensor the the driver's side using a bracket I got from Detail Zone.

GOTHALOSISM Posted October 22, 2010 Author Share Posted October 22, 2010 I'm thinking I'll just drill and tap my setback plates for the sensor. That way they are deffinatly out of the way. Quote Link to comment Share on other sites More sharing options...
deja Posted October 22, 2010 Share Posted October 22, 2010 If I were going to do it again that's what I would do. But that bracket only cost $17 delivered so I wasn't going to pull the setback plate out just for that. I'm thinking I'll just drill and tap my setback plates for the sensor.

GOTHALOSISM Posted October 25, 2010 Author Share Posted October 25, 2010 Yeah, i'll need 2 of them though since I have a b-body harness and ecu. (1 for each side) Now I just need to find out why I'm not getting any injector pulses from the ECU. Quote Link to comment Share on other sites More sharing options...
