From 253/308 to 304

[Kirbs]

Hey guys, I want an old girl but I want a 304 in her. I can't be bothered with the hassle of converting a 202 to 304, So I am planning on buying a 253 or 308 and putting the injected engine in so I don't have to change the box/diff/springs/radiator etc. If I were to change the 308/253 out, I would need to get new wiring/ecu and new fuel lines etc right? Reason I want 304 is because of fuel costs and I am wanting to stroke it to 355, So it would be alot easier to use a VR/VS 304 as they are allready milled out.
Cheers

whats the question? would you need a loom? if so then yes, you will. and yes, you will need a fuel return line.

Plan on changing the box too. Almost all (if not all) 253's were drilled to a trimatic stud pattern to suit the trimatic auto or aussie 4 sp. You can build a trimatic to be strong enough behind a efi motor but the aussie boxes were marginal at best and won't handle the power.

All EFI blocks were drilled to the chev "turbo" pattern and open you up to a heap of other transmission options. Grafting the wiring loom into the stock electrics isn't hard and been covered a heap of times before. You can save yourself some grief in the fuel system by raiding a EFI VL and getting the fuel lines and tank that has a EFI pump all integrated.

You know that mid 85 onwards and all VL V8s are 304s right?

Yeah, Im planning on getting a T5 box and the crossmember from castlemine rod shop. Could I get the tank out of a VN or VS instead?

Yes, I know I'd need the loom but main question was would I need an ECU and stuff because im changing to injected. I'm 90% sure you do but just not sure.

Yeah man.

yes but some vl v8s had t350 or t400 instead of trimatic

yep, not much point putting the loom in without the pooter to run it

Yeah man.

Pretty sure the VN/S ones are significantly different. VL is a straight forward bolt up job and they are very cheaply available.

Add another 10% to that one - you want efi then you will need the ECU.

Thats only the VL Director, had a 4 speed TH tranny. All Vl V8s factory had trimatic. Only time you would get a th350/th400 if someone put it in there.
