So I'm pulling my engine out to fit my new heads, cam etc... and I thought to myself, if I'm going to do that, I may as well freshen up the seals etc, then I thought, If I'm going to do that I may as well stroke it to 331ci... So I've built up a small list of required parts from Summit but I need to know If I'll run into any problems, or If I need any other parts etc.


Can I still run 24lb injectors on a 331 with the twisted wedge heads, cam intake etc? Or do I require larger?

First off, engine bored to 4.030 then fitted with the following:

-Fed. Mogul cam bearings (FEM-1204M)
-Fed. Mogul CP rod bearings (FEM-2600CP)
-Fed. Mogul mains bearings (FEM-4125M)
-Pioneer automotive 28oz SFI balancer
-Summit 4340 H-Beam rods (SES-5-44-05-201)
-Sealed Power file-fit plasma-moly rings (ZR977135)
-Trick Flow 331ci twisted wedge forged pistons (TFS-51404111)
-SCAT 93023 forged crank (SCA-93023)

-Full Fel-pro gasket kit

I already have a Yella Terra 50oz flywheel, but it has removable weights so I'm presuming I can just purchase a 28oz weight from them to replace it......

I'm planning to get the local engine shop to do the machine work on the block, then install the rest myself/my dad. Dad has two garages full of specialty tools and has been a mechanic since the dawn of time... but how big of a job is putting the rotating assembly in?

The bearings, crank, rods and pistons come in at just under $nz2000 delivered, I'm assuming the bore/hone will be around $500.

Just my opinion here but seeing as you haven't mentioned what intake and cam to go with the TW heads, I would consider 30lb injectors for the additional headroom. That would mean upgrading your fuel pump too.

This is similar assembly to mine..
I used a neutral balanced crank..
Which still requires balancing..
what cam are you using ???
TFS 1 ??
Suggest head and mains studs too...
Oh and decent sump or add windage tray, crank scraper
and extended sump to increase capacity...

I have the TFS 1 cam, TFS Track Heat intake, and TW 170 heads.

I also have a Walbro 255 pump and also the TFS fuel rail kit.

The reason I'm taking the engine out is to put all the gear onto it, so i though while i was at it I may as well stroke it if it's not going to cost an arm and a leg to get the machine work done.

Assembling the engine isn't hard mate, you'll be all over it!


Hopefully this place in town doesn't charge much more! I may even just get a quote for putting it together, as looking at videos of piston ring installs, looks too damn fiddly!

If only I had your turbos! Yes I'm using the TFS 1 cam. The kit came with ARP head studs already, So I should buy some new main studs?

What sumps are available to suit our Falcons? I'm trying to buy everything from Summit at once as they charge an arm and a leg for shipping, so I may as well make the most of it. Do I need a new oil pump or will the stocker do the trick?

Planning on using a J3 combined with an Autometer wideband o2 kit.
