I'm cutting it close seeing that tx2k14 is about 2 months away, but I had a 5.3 lm7 iron block that I have bored to a 5.7. I'm really looking for recommendations on my top end parts.


I am about to order a forged ls1 rotating assembly for tsp:
k1 Tech Forged Crank
TSP 6.125 H-Beam with 2000 ARP bolts
Wiseco 3.903" pistons -11cc dish
Clevite main and rod bearings
Wiseco wrist pins
and I'm having them balance it.

Unless anyone has a suggestion on a better cam I was planning on using a COMP Cam Remote Turbo Hydraulic Roller Camshaft K-KIT which includes:
Cam - 235/231 0.621/0.617 115
OE STYLE HYDRAULIC ROLLER LIFTERS
Timing Chain Set
Valve Springs
Retainers
Valve Locks
Valve Seals
Spring I.D. Locators
Magnum Pushrods

My plans for heads were to just use a pair of stock cleaned up used 317 cylinder heads with the springs and valves that come with the cam k-kit. I will eventually get them ported, but I'm thinking they'll be fine stock for tx2k. How much will porting them really help, since I'm going turbo?

And eventually I'm planning to go with a fast intake, but for now I'm going to stick with a stock ls1 intake manifold with stock tb and 42ib injectors.

Planning for 750-800 hp. I've done a ton of research and have seen a bunch of mixed opinions and just want to see if I can get a few more before I start blowing away all my savings lol Any recommendations and opinions will help and are greatly appreciated
Thanks, - Cliff_Z28

Why not use K1 Billet H beam rods as well?

I don't think stock 42lbs injectors will cut it at 750-800hp… Im planning to be around 850hp to the tires on a turbo and I'm going to use at least 75lbs or higher injectors.

I have some FIC 60lb injectors for sale if you need them pm me

You will need more injector...may as well put k1 rods in with it..and since ur already spending that much money I would get a custom cam.

putting forged crank is a waste of $ imho if your under 1200ish hp

Cliff_z28

Thanks, I'll definitely upgrade too bigger injectors and ya'll are right about just going with k1 connecting rods. Anything else

Don't waste ur money on a fast. Just look and ask around what the big power cars use and why not a fast at tx2k14.

Forged crank isn't needed and you'll want like 80 lbs injectors

I run fic1000 injectors on 800ish rwhp. Will find out this weekend how much they are having to work. I have meth to though. Im on a ls1 stock bottom end.

HexenLord

Is that 750-800 HP to the wheels? If that's flywheel HP, you're over thinking it. That much to the wheels has been made on stock bottom end. Keep the stock crank, run shelf pistons/rods.

80 lb injectors can be found for a little over 300. This combo should be able to push you into 4 digits at the flywheel.

I was talking about rwhp. For tx2k I was hoping for around 800whp and after to upgrade to to the thousands

Cliff_z28

Do ya'll think the stock 317 heads re-manufactured with springs and valves from the cam kit, arp bolts, and ls9 gasket will hold up well to the boost?

You need dual springs indefinitely

So how's the build going? You're running out of time pretty quick. Keep a week or two for problems/testing.

Cliff_z28

I know, only two months... I think I'm just gonna take it to LME and have them build it so I can make 2k14

Anchor

They won't be booked out?
