Just rebuilt myself a 302 and put it in front of a recod T5 in a EF body the modifications are as follows. The driveline including the diff hasnt been touched:

Trickflow heads
Standard inlet lower and upper manifold
High volume sump and pump
ACL flat top pistons
1.7 ratio roller rockers
Mild cam
24lb injectors
Pacemaker extractors
2.5' exhaust with twin high flow cats
Cold air intake
70mm throttle body
Autronic computer

At current it makes about 160rwkw. What you reckon? Does this sound a bit low? The inlet manifold is slowing us down but by how much?

If that's the standard HO inlet manifold it would be absolutely killing it. I wouldn't worry about the power output until you get that replaced.

Sorry mate but thats about right with the std manifold. Go Trickflow or edelbrock & you'll find yourself closer to 260+ rw/hp

Is that a single 2.5in exhaust? Cause youd be loosing power there also

lose the single 2 1/2 and loose the standard manifold, other than that it sounds like a great setup!

Good inlet and exhaust you should get 200 rwkw +..
Atleast a broad power band.
Mild cam ?? What specs 2031 Crane ?

Thats good power considering inlet & exhaust...

Mate thats 5 people with exactly the same opinion (RARE! on the forums), i'm looking forward to seeing the increase with the exhaust then manifold change. i'm sure you'll be much happier when the twin system is in place and very happy when the "choked Budgie" inlet goes!

Just got a recent dyno report and the torque curve is flat all the way from idle. max of 375Nm but at 1100rpm its posting just under 300Nm which my brother said was pretty good. The power curve becomes flat after bout 4000rpm. Suspect cause it just cant breath?

YES... Your cam is very close to crane 2020 cam
208/216 @50 112* .530/530 lift 1.6 rockers
-----------------------------------------------
2030 is 216/220 112* .533/544 lift 1.6 rockers
----------------------------------------------
2031 is 214/220 112* .513/529 lift 1.72 rockers
-----------------------------------------------
2040 220/220 110 .498/.498 1.6 rockers
Same as SVO E303 cam
-------------------------------------------------
Your cam specs maybe with 1.6 ratio valve lift
If it is then with 1.72 rockers it would be
513/540 lift ??? At valve..Better with those high flowing heads anyway....

Lets see the dyno sheet! My ute is the same the curve just flattens out after about 4500rpm my problem in fuel/ignition and cam. Yours is inlet manifold and to some extent the single.

Not yet mate, my cam is smaller than yours (175kw). I'm going the computer change first, then i'm going the cam. So far all i've done is exhaust, extractors, ported the heads... now i need the timming and so on fixed then i'll be ready to open her up and improve the breathing. Perhaps turbo's after but thats a lil way away.

Hows the wedding plans going mate? Due for that cam or ecu upgrade yourself yet or are you going all out on the wed and honeymoon!
