What am I forgetting?

For those that have gone through the process, what's the one thing that you wish you had done while you had everything apart for your build?

Well in my experience I wish I gotten everything once. I ended up getting 1050x injectors for my procharged 1LE. I ended up doing a cam install on it but I wish I had gotten a forged crankshaft, pistons and rods along with the new and bigger heads. Because now that I am at 700rwhp and I know the block could handle whatever the blower will throw at it. I agree with the people said about the fuel system. I would recommend the dual or even triple pump to get your fuel needs, you don't need a BAP going bad or burning up your ZL1 fuel pump.

Thanks for the input. I'm hoping the LSA bottom end is stout enough even if I decide to dial up the boost a bit in the future. Everybody keeps going back to fuel...maybe I'll stumble across a deal that's too good to refuse.

A lot of people neglect building up the fuel system. Everyone is worried about getting air in and out and not building up the fuel to handle all that power. Just like suspension most people add coil overs and lowering springs and just stop there.

Those are relatively easy parts to replace... what's the one thing that made you say "shit, I should have done this while I had it all apart"?

Going with a bigger cam from the start. Also, if you decide to swap the fuel pump, bite the bullet and go triples. You might be satisfied with the new power, but even new power starts to feel 'normal' after a while...

That's what my wife is afraid of

I don't know about the cam thing. I kinda wish i went with a smaller lift cam just because it's less maintenance i don't like the idea of replacing my springs every 20-25k miles. I woulda stayed under .600 if i were to do it again. Dual ir triple pumps are great. My plan was a dsx aux pump because it will handle 1000whp on gas, if you're gonna run e85 and want that much power need more pump. Also you don't have to drop the tank for the aux pump. Pros and cons. I don't like the idea of drilling in to the tank. Really depends on your end goals which are very hard to determine when you are just starting out. My end goals changed a bunch as i build lol.

The other option is to drop the rear cradle and you have access to the fuel tank and you remove the pump and I guess while you are there you can add all the bushings for the rear suspension

Already have solid cradle bushings and Z28 rear upper control arm bushings. Not thrilled about dropping the tank but I'm not cutting an access hole under the back seat either.

Yes already dropped my tank once to put in the zl1 pump, we're i to go back in time i woulda have done a dual pump right then. Dropping the tank is a pita

Using the valve diameter to lift ratio of .3 guide....

This video is great for valve events and the ratio above - ratio discussion starts at 12:20

LS3
2.65 x .3 = .649 intake
1.60 x .3 = .480 exhaust

But no one would want to buy a cam with .480 exhaust lift

That said the BTR stage III PD cam awesome - he keeps his exhaust about .595 IIRC.
