A got a little 223 228 114, pac valves springs, titanium pushrods and a trunnion bush upgrade for my LS1 when I did the streetable NA thing when I first got it, very drivable as you would expect, it still needed a little stall, 2800, to not want to pull at lights when in gear
It still works well enough with a PB with the unopened LS1 that still has the stock shift points, it makes a easy 500hp at the wheels and pulls like a train from idle
It has a nice little lope on idle as well running through 1 7/8 4:1, 3" to 4" single with a resonator and rear box, not to loud cruising around, no drone, but, sounds like war at WOT
If I knew I was going PB I would have probably picked a different cam and just upgraded the valve springs, push rods and trunnions
The car perfectly suits my needs of a comfortable quite (ish) cruiser that you can sit in comfortably on the hwy (the Mrs falls asleep within 10 minutes), sit it peak hour traffic for an hour without wanting to kill yourself or orhers around you, or hit the drags for some night time fun
Having a quite cruiser was high on the priority list, I've lived with grumpy drone, loud cars before, and whilst they sound good for the first 10 minutes, after 20 minutes they do your head in
Also, as I've said before, grumpy camed and loud cars are fun, unless you are cruising on the hwy or hit any traffic, then they suck balls
When building a car you need to look at the whole package to suit your needs, from the cooling system at the front to the tailpipe
My advice is to get a big white board and start planning every mod, cooling, engine, transmission, tailshaft, diff, driveshafts, brakes, wheels and tyres
Base every upgrade on the power you want, then head out from the engine to support that power that the engine will throw at it, don't forget to add in safety factor to reliability
Even then, budget in overspend and possible breakages
No point in making big power on the dyno if you constantly break parts
Whilst cars are fun, they can be a biatch
Pro tip: always have a backup daily, a slush fund, and a tilt tray on speed dial
