about how much time does it take for a h/c swap on a 99 ls1. I will also be replacing oil pump and lifters and timing chain. Can some one give me a rough estimate on the time it takes. I have all the tools that have been recomended and my heads are already assembled. Is it possible to completley dissasemble in 8-10 hrs?

 

dissasemble can take a few hours, back together is the longer portion. Have you ever done it before? That is the real kicker on how long it will take.

 

no i have not done a ls1 but have done older sbc before and am no stranger to mechanic work (ATI). will be starting this wed. and hope to be done by friday.

 

Yeah, then you have it about nailed with the 8-10 hr frame. you went to ATI off of 121?

 

what took me the longest was cleaning out the head bolt holes. just a tip i used a drinking straw with the flexible end to suck the coolant out of the holes instead of using rolled up paper towels to absorb all of the fluid and then i just had to run the towel in one time per hole at the end to make sure i got everything instead of putting it in there 10-15 times per hole.

 

no actually i went to the one off of maple ave and I-35 in dallas. I definatly need to meet up with you guys some day at the gtg but ive been really busy at work. Its always cool to talk to guys at the track that are on ls1 tech

 

i was gonna try to vacum the water out of the water pump ports to see if it helps on the clean up

 

it took me 4 days about 6-8 hrs daily

 

Thats a good idea!

 

it took me and friend 18 hours, but taking your time and cleaning all surfaces is the important thing...you cant spend too much time cleaning and prepping, and double check every bolt and use jimx's site

 

sorry to thread jack but is it possible to do with 2 noobs that have never done it before? Following directions of course?

 

Yes...

Its just time consuming thats all. There is nothing really challenging about the swap. Just take your time and be very very careful all while double checking everything. Its really easy to forget something really obvious cause you are doing so much at once.

 

of course it's possibe...just do lots of research in advance...Read www.ls1howto.com , and all the cam/heads install problems that people encountered in this section.

I was on this website for 2 yrs - reading people's experiences, problems and their solutions.... That made my cam swap go like a cake-walk

 

Im at this step now, thanks for the idea!!!!!!!
