Do you know what cam is in it? Tony will get that thing moving I’m sure!
Supposed to be a COME CSBR436. Power is all over by 5300. When he hurt it at powercruise maybe it had something to do with the cam and as a consequence of work done the cam timing is out.
I remember looking at this thing on muscle car sales thinking that power output is not right seems miles too high. Shame you have had dramas with it mate hope it all works out for you

Its prob making 400 ish HP at the fly with that cam.

TK said the same. Oh well like and learn. Will pull it out in July for much more fasts.
rather then pulling it out. Just put a bigger cam.
Relying on TK’s advice. That is unless we know exactly what the specs of the motor are it could be a recipe for disaster. I’d rather know what the setup is to be honest. If its still a 2 bolt setup (likely) go to 4 bolt, more headwork, bigger cam, more comp etc.
But you know what crate motor it is don’t you?
All comes down to budget in the end.
The reality is I have no proof of anything that is in the motor other than words mate.
What gear box you got in this ??
Just be aware if you want power it will all become very expensive, if it’s a entry level come engine and you want a 500-550 hp nearly all of it will be useless beside the crank and a few pieces
how much are thinking of spending on it ??
and what heads are on it ??

Whatever it costs to make decent power. It’s got a t56 behind it so won’t have any box dramas.
apparently come bracketmaster heads
I dare say it will be there entry level 383 motor.
Comp won’t be massive and it will be there ported cast heads.
Could be as cheap as milling heads to increase comp and throw in a bump stick to suit.
All depends what u want out of it. Like manta said (name blank), with
bigger power comes a lot of extra costs. T56 might be good, but is the clutch…
it all all spirals out of control. Hahah
Was told the comp was 10.5:1. See what we find when when its in pieces. I’d like an all day every day 400rwhp. TK can deliver that blindfolded standing on one leg with both hands tied behind his back. Costs what it costs I guess.
It’s not an ls t56 tho only a 215i borgwarner t56 I had lined up to buy the current box from glenn as he was upgrading to the ls style and strapping on CPCs vortech v7 setup from his parted out vr senator build but that obviously fell through lol
I’ll be the one to say the only way to make 400rwhp in a all day every day driver car is with boost
making a holden based 500hp engine to be user friendly just isn’t possible
it will have a massive solid cam in the 250s range, it wont make any power till 3000rpm and keep on goin till 6800rpm
99% chance its goin to to rip your clutch to pieces
spring pressures at the hp are huge and solid lifters don’t last a life time, it produces mass heat and all round a 500hp holden engine will absolutly hate just driving the streets as a daily and will just want to hit rpm and just carnt do that on the streets and keep a licence at the same time
It’s verging on drag car engine in a street car and many people have said iv done it but they are really just trying to convince them selves they have done it because it’s not fun after a while exspecially in a manual
do boost of about 7-8psi and all of a sudden you have a friendly hydrolic cam something similar to how yours behaves now and is user friendly and is nice to deal with and has better street user rpm range
I know it sounds great having a cranky of it’s head engine, but on the street it really isnt and anyone with one will say the same
simple rebuild and blower or turbo if you want 400rwhp in a daily driver
T56 is strong as an ox. Won’t break it unless being an absolute retard. I am absolutely not worried about the box. Clutch will likely need an upgrade.
manta – TK says he can build me a 600hp e85 motor with a hydraulic cam that can be driven around on the street no problems. He is the guru and I trust him above all others.
Not sure where I’ve said or indicated this is a daily driver? It’s a toy. I take it out, thrash it then put it away till I feel like driving it next.

^ I recon your onto it Pete. Only thing I would say is big cubes make realtively easy horsepower for the street as well as boost. Maybe one of those holden blocks I saw that you can take out to 400+ Cubes maybe is an option unless you want to go LS of course
I’d like an all day every day 400rwhp.
^^^ right there is where you said you wanted a all day every day driver
manta – TK says he can build me a 600hp e85 motor with a hydraulic cam that can be driven around on the street no problems.
ok buddy this is absolute crap and if you believe it your just as silly
At 600hp your talking come alloy heads extensively worked in the $5k price tag
13:0.1 comp
a solid cam in the 260-268 range with 0.600+ lift with a rpm range of 4500-8000
a vac pump and evey thing port matched and extensively worked to work in perfection
your cast crank will probley snap after a while, some of the best H beam rod and forged pistons breaching on the custom made end of the market
paying someone to do this will be a $20+k plus adventure and your GRPA manifold might not do it (I dont know that part but I’m guessing it has limit somewhere)
your talking hi rise torque power and 2000cfm throttle body out the bonnet territory
You carnt just magically make a holden engine 600hp and user friendly
i have a mate with a 600hp holden engine and know what’s envolved in doin so and it’s not a walk In The park
i have had a blowen 355 engine with 7psi make 600hp engine and 500 at the treads and even that’s not easy to do
please don’t take offence to this I’m just been honest

Posts: 5 777I know Tk is the man, so no way is what I am saying anything other than a genuine question, or my opinion. Your saying 600, I assume you mean at the crank. That is one small part of the story, especially for a streeter. Two cars can both make 600 totally differently. My car makes 80% of max torque at 2,000 rpm. Another engine might make same power but be peaky as shit and a pig to drive, which is what Pete is talking about. Then you need to factor in lag, I know turbo guys say it’s cured, I say bs, it’s better not cured. You will never beat the throttle reponce of a big cube na ITb or good carby motor, full stop period. But it all comes down to what you want, how much you want to spend, how long you want it to last, and how often you will drive it.
