304 200rwkw 304??

Roller conversion are good, but as mentioned you need to get the right lifters, they are definitely available. Can be had for reasonable prices these days too.

Cheers mate. So can anyone answer what can be done to the T5 box to make it handle more power. Not sure how much they can handle stock but don't want to break it. Also a single 3" exhaust will work for a 304, 355 or 383? Don't want to have to buy 2 different exhausts

Twin 2.5" with twin cats into singe 3" will support a moderate 355.

The T5 is a reasonable box but has it's limitations and how long it lasts depends on how it's driven also. There are some upgrade parts available, see T5 Transmissions

Cheers mate. Spoke to an engine builder yoday and he gave me a bit of a rundown.
And I drive my car gently.....most of the time haha

Is this any good or do you think the price will reflect in quality?

That's a Procomp manifold. Put the name into google and you'll find the information you're after.

The price certainly reflects the quality and for a good intake you'll probably be looking at spending upwards of $1500.

So the general consensus is they're runbish? I didn't realise they would be so expensive. Are they needed straight away or could it wait till a little further down the track?
So far I've been told to get exhaust and cam and tune to start with

my 304 is making 275rwhp/202rwkw
cam is very conservative, easy to drive in traffic
gets 10L/100km on the highway with a 5 speed

It's nothing over the top - cam, flat top pistons, stock VR heads, aftermarket intake (Trickshift), roller rockers, headers/exhaust & tune

 

[Immortality]

Yep, get some decent compression and things open up performance wise

That's what I'm aiming for. Good to hear it's economical too. Is it a off the shelf cam or custom grind? Also how does it sound? What sort of exhaust, single or twin? Would love some details on parts you've used mate.
