this week im getting a cam, edelbrock intake manifold, ported TE50 heads etc in put on, in my 5ltr. I was wondering if i will need a bigger fuel pump, injectors or chip. trying to get it up around 170-180rwkw.

What model V8 Falcon are you fitting this gear too? Which cam did you get?

You may need to get a chip, really depends on how big the cam is.

If its going into an E-series, you'll want to upgrade the MAF and most likely the injectors will be at their limit at 180rwkw.

As xr8ute said, depends on how big the cam is but generally the V8 EECs can cope with most mods. Fuel pump can handle 200rwkw but its always a good idea to replace it with a decent 190 or 255l/hr Walbro one. Chances are you will need some larger injectors and a MAF to suit. The stock 19lbers will handle a max of around 180rwkw but you need to bump the fuel pressure up a fair bit with an adjustable reg to get there, and even then its not a reliable solution. IMO just do it properly with some 24lb injectors and a C&L or PMAS MAF from the US.

Getting it done to my EL Fairmont through Mick Webb. He's already got a cam for me but unsure of specs yet. so u reakon bigger injectors, might as well just ask mick while he's doin the engine. he said i might not need a chip as the factory ecu will gradually learn with all the things im changing.
