For the timing:
Naturally apirated: 35 degrees total advance at 2400 RPM or higher, full throttle
Boosted: 28 degrees total advance is a good ballpark figure to start with

Jetting for which carburetor?

any ideas on jetting and timing settings?

any idea wat jetting ppl ran and wat size emoultion tubes?
need to get that water sprayer in any one have a spare ress bottle and a little time to install for me??:)

I think thats your problem dude. 15psi and no water/methonal, intake temps will be way to high. You could try richinig it right up I guess. What a14_force said is the way to go, just get an a/f ratio meter and go for a drive. At least you will be able to see whats doing. You could even try a bottle of octaine booster and see what happens.

its draw through setup so doesnt need that much pressure but i could do with an elec pump u offering one mik? :) need that cluch i think the one i got either slips under boost or i spun the wheels and didnt feel it ??????

stock pump wont put out enough pressure for boost, you should have gone elec with a pressure regulator.

4psi fuel plus 10psi boost needs 14psi fuel pressure almost from memory

nope no water meth in yet. We have locked the dizzy so it won't advance but no matter how much you retard it it's still pinging. Tommo said we should put a sniffer and see wats going on wit fule, as i'm still running stock pump and all of the motor is standed a12 round port. Lol i'm running 98 and bp5es plugs should i go colder? I'm running about 15 psi lol at 6000rpm no load cant tell i think around 10 at 4000 then it ping's

dont think he got the water meth setup going yet, and that may explain it.

stick a wideband A/F meter on it, and see what your air fuel ratio is. Lean wont help none. I've experienced pinging at the same revs yours begins at too on old motors of mine. A trick you can do is lock your dizzy, and see how much total spark it can stand. Then pop rivit a clear plastic 360' school protractor to an old rotor button. Then hold the bottom of the dizzy shaft in a vise. twist the rotor and see how far it moves. remember that 1' at the dizzy is 2' at the crank pulley. Unlock your dizzy, and build up the slots with weld untill it's only able to mech advance to the max spark it could stand when your dizzy was locked. That way your engine isn't having to contend with too much advance in the lower rev range.

lock dizzy as said ... run 98 octane ... you'll need bigger jets but just turn the mixture screw out and see if that helps the pinging
