Critique my engine build
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!

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.

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.

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.

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...

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

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.

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

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

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