Hey guys just wanted to talk about my engine plans before I open up the bank account and start buying parts. For me it's kind of a talking out loud thing, but this is my first LS build and I truly value others opinions.

LS2 alum block 4.005"
LS3 heads no porting
Callies 4" dragonslayer crank
Callies ultra h beam rods
Gibtech billet aluminum pistons

I've done some research on timing chains and decided on the Manley 73234 because of the Torrington bearing (would like to hear opinions)

Melling 10296 oil pump

i had a custom cam specd out by Brian Tooley

I have an ecs kit with a novi 2200r, at 7500 rpm the blower will be at its max rpm

The car is mainly a street car, but I don't drive it that often. I am looking to get more involved in 1/2 mile racing but it mainly sees trips to Mexico and a few 1/4 mile trips a year. Let me know what you think!

Only thing I would really advise is to have the block dry sleeved or even potentially Superdecked by ERL. Best time to do it right is the first time around.

Unfortunately not in the budget

Unreal

Then that motor won't support a maxed out 2200R. Spin the blower slower.

LSA heads instead of ls3 heads. ls3 heads will lift and have gasket issues a lot sooner.

I would go with a lower end crank/rods and spend the money on the heads/block IMO.

Almost identical to my engine other than I use Wiseco pistons.

Not sure you need to go to 7500. You would be over spinning the blower and as Unreal said, lifting heads might become an issue.

ZincGT

They are technically heads off a G8, probably doesn't make much difference. I ran it to 7k with the stock motor (243 heads) and headstuds. IW 10% overdrive pulley and 3" upper. 20 psi.

realcanuk

I don't remember exactly but with a 3.0 pulley, and 7500 rpm, you are probably over spinning by 4 or 5000 rpm.
Not sure it's worth doing. Pulley it down and stick to 7000 might be safer. Still wouldn't bet against lifting the heads though.

ZincGT

what is the step up ratio 3.4 or 3.45? I guess you are correct, i just switched to a ati balancer and it 8.235 inches and at 7k rpm its 65k with a 3.4 step up...

Unreal

I would stick with a stock crank and compstar rods and put the money elsewhere IMO.

ZincGT

what setup are you guys running?

realcanuk

Not sure the ratio. Vortech has a calculator where you just choose YSI or V7, which is the same as the 2200.
I'm running a YSI with a 3.0 pulley on a 402.

ZincGT

Did you sleeve your block?

I really dont think 1100 hp is to much to ask of the alum block.

realcanuk

I did not, but at the time I built it I was thinking around 700. I have no problems at 1000 now, but it's a street car. If I was going to race it often, and really push it, I would have probably gone a stronger route.

Unreal

I'm running a LSX block setup, but budget wasn't a concern (well within reason).

realcanuk

High roller

Unreal

Yep, but not high enough to run them bling bling gold rockers.

ZincGT

well guys Callies is 11 weeks out on LS cranks, any recommendations on a 4" stroke crank? I'm still calling vendors looking for one.

chpmnsws6

Stick with a stock crank. Good rods and pistons will take you places. Spend the money saved on good heads or other essentials.

ZincGT

Looking to do a 4" stroke, I have to buy a crank either way, I would just like to have the piece of mind.

Unreal

Stock crank will max out a ysi. Address the heads before worrying about a longer crank. Stroke is far far far overrated.
