I finally got a good 6.0 iron block to work with. It's going to the shop to get tanked and new cam bearings. My plan is

New lq9 pistons/rods. Unless I can get forged for the price of the whole rebuild kit. (~800)
Gm crank.
Rings not sure yet
Arp 2000 rod bolts
Afr 205 heads. Got a steal on these
Ls6 cam. Only cuz I don't want to mess with a stall til I get everything ready to pull. Ls6 will go eventually.



What can I look for hp wise with a lq9 afr205s and a ls6 cam with a good tune?

The cam is what will kill you. I would guess 380rwhp with that cam. As long as you are going to use a good set of LTs and exhaust.

Ya I figured as much but it's what I have laying around at the moment and I want to keep the power down until I can save some more to buy a yank3600 and a lvl 3 4l60 for flt.
I got these heads complete with 0 miles. Only run time. For less than half of 2300 retail with the dual springs (.600 max) and titanium retainers.

I would think at least 410 with a t56. Bolt on c5 z06's make 380 or a hair more with less displacement and worse heads. to the op though it looks like a good build but I would wait and get a better camno sense in doing it twice.

Yea I should but I just spent 1k on these heads. I wasn't planning on doing heads other than home ported 241s. I couldn't let these slide. It's not hard to swap cams out of the car. Or in it. I have been looking at the "mamofied" 205/228r 500hp thread and I really like that. Although I won't be going that deep into my pockets. I guess I should have gave more detail.

Stock 4l60 I do plan on upgrading like I said.
Stock 10 bolt Ill mess with it when it blows.

With all my plans I'm fully aware that the ls6 cam is holding me back but it's temp to not completely thrash my trans long enough to save money for the stall and lvl 3 60e. It's my daily driver too so that adds to the ls6 cam for stock or damn near close to it drivability.

I don't plan on making 500+ but I'd like as close as I can get. I'm not ever going to change heads since I got these pretty ones. I just want to be one of the fastest baby cammed fbodys in my area putting a beat down on 5.0s vettes or anyone else. But 97% of my cars miles are strictly kept to the speed limit all city no highway. I baby my car.

You will be very close to 400RWHP through the 4l60e. Just save some money and get yourself a bigger cam and stall.

Close to 400 with the ls6? Flywheel or rwhp?
It's all in the plan but with the purchase of the afrs I have to wait longer for a stall/trans.

Why not just find a Torquer V2 since it will work with the springs you have. Would be a lot easier with the motor out of the car. Much easier to install the pick up and o ring in the oil pump etc... I would also at least do the comp trunion upgrade. My stock(as far as I know)4l60e with VIG3600 is holding fine with this cam and ported 241's and occasional N2O. You will obviously be making more power, but it should last a while if you drive like you say. Just put a big tranny cooler on.

I don't want an off the shelf cam. I want one specifically built around my heads and for my 6.0. It's not that I don't think it will last, it's that I KNOW for a fact it's been abused its whole life be previous owners so I want to start a new slate. It won't hurt anything but my wallet and I know it won't break for a long time being all new.

Awwh man I saw those heads on the wtptc facebook page, seemed like a good deal!

(sorry for the off topic-ness op)

i got them for less than a grand soo i think i got a hell of a deal.

now.. isnt 2.02"/1.60" valves bigger than stock?? if so what pistons should i run with reliefs to avoid valves hitting the pistons?

I can understand that

I've got a set of rockers I'm going to do the trunion to.
Oil pump wise would I be fine with a tsp ported one? For lifters I found on scoggin dickey they have a "kit" with a set of ls7 lifters trays and bolts for 130$ ill get that.

What should I be looking at rings wise? I don't want to spray or boost. Not on this engine anyways.

My block is missing main caps. Will I be fine with oem replacements or should I shell out for the billet ones(500$)?

I want to get some forged rods around (700$) to spend there. I've been looking at compstars. I want lightest possible within budget.

Pistons I don't know what to run since I believe the afr valves are bigger than stock and I want to be safe and have some valve reliefs. Any suggestions?

For the price of stock LQ9 rods and ARP2000 bolts you can get a nice set of foged Scat I beams with ARP bolts. Pistons you can probably find a decent used forged set for $500.

That way you have a forged rotating assembly for under $800.

14k

Would scat I beams be ok? I haven't seen much on them. I saw them on tsp for 3-400 with no arp bolts. Only reason I'm forging is for added safety. I don't want to spend all my money and stock replacements and break them.

Forged I beam rods will be better than stock LQ9 rods that's for sure.

TSP has them with ARP 8740 bolts for $309:

Another place has em for $283 also with those ARP bolts:

Are those forged? I looked but didn't see it anywhere.. I like the price but would I be ok buying these? I know internals aren't a place to skimp out on.

Be careful laying your heads down on that bench I see some screws that could scratch em up pretty good. Afr heads you better treat them like gold.
