hey guys getting ready to start a swap, i had planned on doing a lq9 but i can get a ly6 with about the same milage for only a few hun more. plans are this...

vic jr and big carb (pro systems)/ msd setup with a plate kit 175-200
Tick cam and valvetrain including vvt delete if i go ly6
deck and stud the heads with good valve job and hand port
rod bolts
GM performance oil pan kit
dynatech headers
glide/th350 with nos conv


So that being said is the ly6 worth it. I know the heads are killer and they already have factory valve reliefs. I can get the vvt delete for 120$ from texas speed so if thats the only flaw its kind of a no brainer but this is my first ls engine build so i just wanted some input. Thanks in advance

What heads are on the LQ9 ?

What car this going in ? (may want to re-think the GM performance pan)

You had a short block ***, and it needed to be rebuilt or some dumb crap. So you didn't have a LY6, you had a 6 liter short block. Throw 317s on it and you woulda had a LQ9 basically.

everyone is so obsessed with those damn square port exhaust restrictors.

Nice sword fight gentleman, its going in a mustang. All the lq9s I can get have I belive 317 head's. I can score a 76k ly6 for 1250$ lq9 is 1000$ with 81k

Whats the deal with the pans? I am runing upr k member. Sapose to clear it.

they are both basically identical with different heads. the ly6 has a very small valve relief due to the gigantic intake valves on the square port heads. it all depends on what you're after.

i see that you plan to do a valve job and port. the nice thing about the square port heads is that you only need to port the exhaust side for the most part. the smaller valves of a lq9 would give you more leaniency with cam selection due to PTV issues.

Totally worth the extra 250!

yep, i'd take the LY6 on something as light as a mustang. also with a LY6 you're guaranteed the full floating pistons and stronger rods. win/win. just hit the exhaust side and barely touch up the intake side of the heads

Thanks so much for the info guy's. I will get that ly6 coming and start a build thread when I start on it.

Are you guys running aftermarket rockers or did you do the trunion kit?

Doug G

They're Hummer pans and hang low in cars.

punisher95

Oh ok I didnt know that. Thanks

What trans are you running? Any track times? What size cam did you go with?
