Success! Good to see a running engine :) Are you also going for a bit more carburation?
Yes it does feel like a mile stone having a running engine.

"carburation"
Yes, but just want evrything inplace first . I can then start playing and making things shiny :lol:

nice

easy move to turbo after that

boost reference your gas regulator... its basically a hole and a pipe fitting in the right place

yer LPG has a RON of over 100

good catch on the sticky lifter being linked to a push rod that couldn't turn

well i run this in my hemi 6

3.45:1 rear end

1st 2.46:1
2nd 1.78:1
3rd 1.27:1
4th 1:1



a similar cam from the same manufacturer for 318 exists but is 2 further up the list of mild- wild when applied to a 318 v8 with a plenum based inlet

company has just shut down so i can't find the specs.

i while back i posted up some stuff on dynamic compression ratio and a link to some software... really handy

if you can't find it i'll dig it out again

are you pulling the heads off or doing the valve springs in situ?

Going to make a tool out of a spare rocker arm bar and a lever , , dont fancy the rope trick.

So compressed air I think, this gave me the idea :thumbright:

Best done with compressed air, the position of the spark plug doesn't help with rope, though it works fine on a big block. A gutted spark plug makes a good adaptor and can double up as a piston stop if you design it to suit.

Rope trick worked perfectly for me on a small block. I always worried that using compressed air could create an issue if the keeper was sticky and the spring compressor opened the valve a little, then all the air would escape. If the piston was at BDC (which seems likely with the compressed air in the cylinder, the valve might drop.
Having said that everyone uses compressed air so I concluded my fears must be unfounded - either the pressure is always enough to overcome any stickiness and/or the pressure isn't enough to send the piston to BDC.
For that reason I'd probably use air next time, and the gutted plug always seemed like an easy way to do that. (I don't think the adaptors are that expensive if you wanted to buy one?)

i always use rope as it's a mechanical stop for the valves. i wouldn't worry about the valve dropping into the bore when using compressed air though, you'd just put each cylinder to tdc in turn so the valve could only drop slightly 'til it touched the piston.

both processes only work if you remove the retainer on a valve that has rope or air under it..... :) as i found out

new head gasket necessary....

tried a magnet on a rod to pull it back up...... no luck

i'll timed phone call for work, and i lost concentration and my place.

and give all of the retainers a tap on one edge before starting to release/unstick the collets from them too. :thumbright:
