Was looking at 3:9's as well but want to keep rpm at 100km/hr reasonable ie 2400-2600rpm.The pacies seem the go,I was just wondering if there was something better.

Pretty sure 3.89:1's will put you at about 2400rpm @ 100km/h.

Thats what I'm looking for but everone I've asked before has has come up with different revs.Do all btr boxes have the same ratios?

Pretty sure the ratio's differ between the 4L and 5L's but all the V8 auto tranny's should have the same ratio. Theres a diff gear speed calculator on here somewhere, if ya do a quick search it should come up.
Remember tyre size affects this aswell, but the calculator takes all that into account. Also as chr!s said above, what form of tuning/ecu are you using?

Stock ecu with chiptorque chip.Probally around the same power but I'm more of a fan of N/A.Hoping to get around 210-220 rwkw's when all sorted out plus the sound of the thing through the twin exhausts is great.

I bet it sounds great mate, you able to post up a sound clip? As far as tune goes, i think you'd be better off ditchin the chiptorque and gettin it tuned with a twEECer or a CAPA eliminator chip.

Ixlrate tried the capa elimanator chip and had a lot of probs.Havent heard anything good about them yet.Does the tweecer need the use of a dyno for regular tunning.

I havent heard bad things about the capa chip yet, but then again i havent heard of alot of people using them for the 5.0L's. The twEECer is a much popular form of tuning and i've seen many 5.0L's using this all with great results. Dont think a dyno is compulsory to tune with, if ya have a laptop im pretty sure you can tune while on the fly.

Few minor things were out,valve adjustment,couple of fouled plugs and stall convertor.Hoping to get a bit more out of it with decent extractors and porting lower manifold if needed.

would have thought a stall would make any difference to dyno runs?
when you say porting the manifold, I assume you are refering to match porting/ gasket porting it yeah? |
