Below I discuss why I think this is a great combination for an LS powered street car or boat.
I did take in an order for one that was canceled.
I show it at the bottom of this page. $10,500US or $18,000NZ
Most street cars don't need to rev over 6000 RPM, therefore having a motor that makes peak Hp above 5500 RPM has no real advantage.
This real-world test shows how much torque can be increased by narrowing the LSA.
Vacuum at idle will be minimal, so power brakes could need help.
212 degrees is plenty and will take the power curve to 6000RPM.
The engine below has a Truck Norriss cam in it with a tight 107LSA. Vacuum at 750RPM is 11 in Hg
While stocks remain I recommend starting with a $6100US 19434644 new GM LS3 long block and swap in a better camshaft.
Again because of the lower RPM requirement, I suggest a dual-plane carb manifold. The goal of this combination is to keep the final cost down and not make power where it is never used.
Carburetors are pretty foolproof they will always get you home. Cheap TBI are not so reliable, so I recommend the new Sniper 2 if you want EFI.
Using a $500 MSD box solves the ignition requirement and you can use powerful coils.
I like these $400
Davis Unified Ignition SOS ignition coils.
This is just one combination built on the LS3 long block, many other options are available.
With the addition of a water pump and alternator, you have a complete engine.
You can customize the engine some, eg. swap to nicer-looking valve covers.
Shipping to NZ will cost approx. $850NZ plus approx. $550 in fees after arrival.
You pay that over there.
This is a look inside my shop.
This is me.
