Winter tidy up ready for new heart

[Mikethepanel]

Regarding your dry sump pan , it's hard too tell in the pics but it looks like it doesn't have the cut out too clear the steering rack so if that's the case then that's why it doesn't fit .

I have changed the sump pan to one with a cut out but its still very close.
Now i have the gearbox in its about 3mm away from the rack

The engine shouldn't move but sounds a bit close on big jumps etc . Maybe you could raise the engine mounts up with slots or something ?

Soon be baaaaaaaaarrp baaaaaaaaaaaaaaaaaaarrrrrrrp
Eh gaz

lol , it will sound the nuts . Try some longer trumpets when it's on the dyno as i'm sure those stumpy ones will lose power .
What's the engine spec ? Looks like a 200 block and multi-shim head gasket too me and the porting looks good .

Briefly its a 2.1 cossie crank,steel rods,woosner pistons.12.4:1 comp ratio,multi layer head gasket,custom cams and 45's

Core plugs won't fly out!?
People use a cast iron water pump off a turbo Yb which produces about 80psi of water pressure at 6000rpm

With the alloy pinto pump you have fitted mike the water pressure is about 55psi at 8000 rpm, and more than enough cooling!

Also the shorter the trumpet/ inlet tract normally would equal more bhp at higher revs!

Longer trumpet/ inlet tract the more low down grunt!
Also choke size is very important, so watch that when she is on rollers
The good things about carbs is that they can self compensate on fueling due to the amount of draw on each cylinder!

Keep us posted how it all goes!

Very interesting . I have a normal pinto water pump and 93mm bore and the core plugs would fly out until i bolted them in . Not sure why but the tuners i spoke to at the time reckoned it's a shock wave through the water jacket at high revs but the jury's out .
I tried lots of trumpet lengths on the dyno and short ones were crap on mine so i used the longest ones i could and even had spacers made to make the inlet tract even longer . Worked a treat on my spec but every engine spec is different so only experimenting will tell . I've had over 150x dyno runs to get the optimate settings etc and we tried most things and some of it is just splitting hairs , lol .
