im thinking of rebuilding my LS1 due to a retard working on my car and completely munking up my head. I would do just a head cam pack. but im terrified not to address the bottom end since it has 116,000 miles on it.

If i reuse the crank and have it ground and a set of eagle h beam rods and diamond forged pistons plasma moly rings. my bottom should be pretty stout right???? spray is in the near future (200 wet shot) . should i be alright w/ this set up??? or should i go another route . im trying to be as low budget as possible but still keep it strong / reliable for road trips to the beach and stuff like that.
i want to go w/ a head cam pack that comes w/ everything rocker lifters pushrods the whole shebang. i see patriot performance is about the cheapest. any good/bad reviews on their products or any1 elses ???? like i said above im trying to watch my budget as much as possible here but need reliability/ performance

i want a killer hit and as much reliable hp/tq as possible. any suggestions about which cam to go with or LS1/LS6 style head .how much should i bore the block (for power reasons) ????? the car is a 02 - M6 .the car isn't a daily driver but i dont want to go to radical and get the noisy valve train /reliability issues (appear stock but whoop *** through the lights). this is the 1st motor i have ever really tried to build from the ground up so any suggestions on set up and products would be greatly appr.


i have talked to a few local ppl and they dont know **** about these engines so its up to u guys. or any links w/ proven setups

any help PLZZ

on a stock stoke ls1 stick to 200-215cc heads with 1.89 to 2 inch intakes + 1.55 exhaust
which is more than enough to feed 7000 rpm + .7 in valve lift if the valve train copes.
.6in lift + conservative to moderate durations seem to do the trick on factory intakes
if you want more boot but don't mind less idle vacum run narrower lc at it will make it more 2 strokeish

Well you can more and likely polish the crank, as far as the eagle rods and diamond pistons I havent ever put them in a motor but they are very nice looking and are real good quality Im sure. As far as the Block you cant bore it but you could probaly take it and get it honed and heads I have seen a lot of success out of the Trick Flow heads and I personaly would like to have a set of Darts that someone that is reputable touch them up because that is what I am saving up for myself is the Darts. Go with NOS NOZZLE kit if any nitrous kit because if you spray it though your throttle body the gas will puddle up in you intake and burp up because that the reason I have a 2002 LS6 long block because I crack 3 sleeves in my block with a nitrous express kit. GOOD LUCK

yep i like the Trick flows but there a lil $$$$. i found a few posts talikg about Patriots heads and they talk like the mill work was crap !! any1 have a set of patriot heads and if so ur opinion on them. get, stay away from . how about a set of World heads ??? and as far as the springs that come w/ these head packs. are they good enough or do i need to consider throwing a few extra $$'s here. the car WILL be sprayed from time to time at the track. i found a rebuild kit w/ reground stock crank, diamond pistons, eagle h beams 6.125 rods , mahle plasma moly rings and all federal mogul bearings just no gaskets for $1495.00 does this seem decent to ya'll or should i go $500.00 extra $'s and get the 383 package w/ eagle 4.000 stroke.

any suggestions on a decent all around cam that loves the juice.

and i will be running a diff. intake and T/B maybe not at 1st but very shortly. can i port my stock ls6 intake to match the heads, or dont worry w/ it and just spend the $ on the aftermarket intake

call texas speed there heads and cam packages are really good! in my opion if u want to spray go 383 the extra stroke will help the tq and the spray will react good to it! nos is a great kit but im a nx guy but what ever kit u get keep the nozzle as far as u can from the throttle body so the fuel dont puddle! not tring to be one sided but also talk to texas speed bout a bottom end kit they usually have the best price!

thanks i was just looking on their web site . as far as the nitrous what about a plate system ??? any 1 here use one for a wet shot or do most ppl just spray in front of MAF . the car will be tuned for the nitrous when it is added no pray and spray here i deff. want it to stay together but get as much as i can from it.

does any1 have any links to different set ups and dyno charts or hp/tq #'s or possibly ET's just as a close ref. just so i can try and figure out which way im gonna go here. and how much of a nightmare is it going to be to get motor out or poss. labor charges. Im just above North carolina Greensboro area.

nx makes a maf plate thats what i use and i love it! if it a wet kit u need to put it behind the mass air meter! dry goes infront of it

ksk1980

iTrader: (33)

yeah thats what i thought
id be srraying behind the MAF but they make a plate wet kit that goes behind the TB right?

blackn2oss

iTrader: (6)

i think they i remember seing one that goes behind the tb but not for high hp shots i like th plate like i got tha mounts to the mass air meter it gives it more time to atomize

i just found a 346 forged short block for $2495 , but i priced out using my block and a diff. reground crank w/ oil pump gaskets and all except cam bearings for like $2800 for pretty much the same set up with machine work and all not to mention intake w/ fuel rails and T/B and the under drive pulley

but to go w/ 383 other than the crank is there anything else diff. needed??? pistons different bore size and how big of a bore can i go?? like i said im new to the LS1 build here not sure what u can and cant do

blackn2oss

iTrader: (6)

im building my 383 now all im waiting for is is the diamond custom pistons but in going 2 stages of gas 150 out the hole the a 200 on the second gun! but i went callies crank and rods with the diamod pistons with a 3.905 bore. 3.905 is the limit for high hp motors and the best performing bore. but thats my 2 cents worth

ksk1980

if y dont mind me askin how much is this gonna run ya??? w/o n02 set up just motor and machine and how much HP are u lookin at w/ ur set up?

blackn2oss

iTrader: (6)

i got a good deal from texas speed arp main studs rod and main bearings calies crank and rods and diamond custom pistons was 2816 and sum change shipped to my front door! as far as motor power i hope for 450 to 500 range with a 11.4 to 1 compression ratio.

ksk1980

iTrader: (33)

yeah but for that price my bottom end is assembled ready for the cam and heads to be installed so hopefully i'll be coming in at less than $5000 tune and all . everything but spray

blackn2oss

iTrader: (6)
