Thanks for posting. Simliar set up to mine as well. I also agree that the strokers are the way top go to achieve bigger numbers but I am a staunch 308 fan and wanted old skool 308 power as not too many go down that path anymore simply because of the relatively cheap prices for the stoker kits nowadays.

Ta, good read indeed. Fair bit more HP than mine though, 400 out of a non stroked 308 is pretty full on. Some big cam choices in there.

Hi guys just thought I would add my combo. Don't have any hp figures but its best at willowbank is 12.20@110mph.
Stock stroke 308. standard bottom end with flat top pistons .060 over. Heads are red hq hreads, ported to roughly l34 spec 1.94 intake valves and 1.6 exhaust. Crow cams solid. Stripmaster manifold. 2" hvh carby spacer. 750hp street carby down jetted. Roller rockers. comp was 11:1 static.
Before the 750hp street carby I had a 650dp holley with a best of 12.40@108mph bolted the 750 on and dropped 0.2 and picked up 2mph. Had to drop 3 jet sizes all the way around but thats it.
Thanks

Good times indeed. I managed to snap an axle in mine yesterday...Time for some billets I think..More money :-(

[Redslur]

Wow impressive. Must of had some good compression to get those sorts of figures? Any cam specs?

[AbsynthHatch]

boblhslr very similar combo and times to my Hatch, was interested if you knew the cam specs at all?

[boblhslr]

Hi AbsynthHatch, The cam is a crow cam # 5803. Duration 282, duration @ .050 in-246 ex-246, L/C 108 and valve lift is .540 in both.

i havent added to this for a while. been busy with the car.
i`ve rebuilt my engine, just a freshen up, new rings and bearings, i had hurt the mains, but caught it in time.
dont know if a mentioned sprint event i did, i actually got oil surge, 1st time this has happened with the sump i was using(high energy pro circuit),
well after chatting to some people, and some sponsor help, i have fitted a dry sump setup to my engine.
oil pressure is the best it has EVER been.
just finished running in the engine, and have been sorting some teething issues.
if all goes well i plan on hitting the track ( for the perth people, its the twilight sprint at kwinana)
so fingers crossed, been almost 6 months since last event, im hangingfor this.

Make sure you post up some figures if you get ti dynoed...Be good to keep this thread rolling along!

[Redslur]

Good starting point. My only comment though is with the 286 crane you are lucky to develop power after 6k so 7k would not happen. I swaped from the 286 to the 304 Crane (next one up) and the power started rolling over at 5600rpm. The cars certainly revs a lot harder than 5600rpm on the road. Mind you that is what the Performer dual plane manifolds are rated to so perhaps that is why power stopped climbing. Mine made 210 RWKW @ 5600.

Be interesting to see what you end up with. Post up your results. Keen to see.

holden 308 loves fuel,put a 800 holley on it.my friend had a 800 holley spreadbore double pumper.cc300 crane cam.top loader nine inch 3.5 diff gears,ran 11.6 @119mph in a holden hg ute 25 years ago.back in those days most people used manuals.i am a big belever in using manuals as it teaches people how to race a car at the drags.back 25 years ago these were quick times.thanks jason.

Go the STICK SHIFT.

[Redslur]

We have our annual dyno day in a couple of weeks so it will be interesting to compare notes on another dyno. We have some very staunch engine combos in our club so will be an interesting day indeed.

[Redslur]

Nice effort. Surprsising result using the 286 camshaft. Big power jump from your last combo too.

[Redslur]

Any power figures Wayno, keen to see your results.

After seeing my two mates run their cars at the drags yesterday and post good quarter times, I kind of wish i went for a small solid cam now like the CC280. Maybe next time :-)
