Hey Kim... Your "timing" is coincidental!! I literally just figured out my cylinder pressure is too high for that Cam, and so will have a new Cam ground and fitted to hopefully alleviate this issue once and for all... Meanwhile I'm running an Octane Booster to give me approx 105 RON Octane and...

Thanks.... What you've said totally makes sense. I have liaised with Gary, and he is of the same thinking; - being that it is not an exotic build, and that Poly chamber design can / should easily be able to accommodate 10:1 CR, and more, as he has proven. Verifying the basics first would...

Thanks!

Thanks again... I also agree it can be a good learning exercise, especially given most everything is new/fresh, and a "known quantity" I appreciate your suggestion to pull heads and replace gaskets etc, but that won't be happening unless absolute worst case scenario we can't get to the bottom of...

Please read original post regarding the distributor... Also, my previous comments regarding accuracy of TDC; Cam was supposedly dialled in from very reputable engine builder; wideband seems correct - however dyno test/tuning should hopefully confirm early November

Yeah I've already done all of above hey... Except post on general forum! Engine builder bump steers me to tuning specialist in Daylseford, but I'm going to try a local dyno tuner in Mornington in about 5 weeks... That way he can verify the timing mark I've had fabricated and set up (I've...

Thanks for your input! I have already tried disconnecting the vac advance and running with 10,8,6 deg.if initial and it still detonates unfortunately... And at 3/4 or full throttle I'm thinking I would have nowhere near 19" of vac for the vac advance to be activated I (should) have approx 12/14...

Okay I'll definitely try those and report back , hopefully in a few days time

Definitely at 3/4 effort, and also floored, from memory

Yeah, plenty... Mild cam and all

Please read the vac adv specs I provided... No vac adv until 19" (light throttle). I'm not having any issues until I push her significantly...

You have higher comp than me, and can run 12 deg initial... That is a very different scenario to mine... I should be able to run 8/10 deg initial I would have thought...

Great question... I just thought of this, via searching the FBBO site. I am currently using the recommended Autolite 85 spec plugs... My ground strap suggests that this plug may be too hot for my application ( I have no timing / colour change until right at/on the base ring) So, I was...

I have a 62 Dodge Dart Sedan (in Australia) which I've had a stroker 318 Poly (now 392) built with mild cam (222@.50, .450 lift, running a 2bbbl Holley 500cfm (AFR's: 12.8 - 13 @ Idle and Cruise, into the 10's under load). Everything is new, and engine is balanced, 10:1 compression, running...

Hey! I'm still at a loss as to why my fuel is "evaporating"/ disappearing so rapidly It's rather frustrating that everyone is saying that's what fuel does these days, yet I never had that issue with the first carb I fitted; nor with the other cars I had Holleys on in the last 2 years Your...
