Hi Bryan, yes, definitely need to get our cars together! When we have our engine back together... :rolleyes: :D

Hi Chris, Bit further south, down near J8 of the M1. We'll have to meet up at Santa Pod if you get your car there when finished :thumbsup:

Hi Bryan, good to see you on here. Its a great place for advice, usually more than you'll know what to do with! See you around, Rob

Hi Chris, I look forward to seeing the finished article! Whereabouts in England are you?

Thats good to know, thanks

Thanks for the quick response guys. Doug - do you know what size o rings you used? Or were they just sized to fit snug under the plug head?

We know we have a vacuum leak on our 63 Polara 500's intake so have got a gasket set ready to fit over the next week or two but are wondering what type of seals are supposed to be used under the 6x access hole plugs... can anyone here advise what's best to ensure they don't cause a leak too? We...

Yes, that much we do know :D

Good answer, thanks :thumbsup: The build sheet we got says the cup depth is 0.320 but that's under the heading of 'tappets'. Would that be the depth in the top of the lifter or under the rocker where the pushrod (hopefully) locates?

I agree, 5/8 turn = 0.026 so well short of the .040 - .050 they said is what's needed :rolleyes:

Best reply so far, thanks :lol:

That is a lot of plunger travel, I was told it was more like 0.140" ! The Hughes info I have says for cast iron heads and block, use .120" -.140" pre-load, which is waaaay more than any other recommendations I've seen.

They are 3/8", 24 tpi, ie 1 full turn = 0.0417", so our 3/4 turn is only 0.03125", so well short of being mid-way thru the lifter plunger's travel :rolleyes:

Thanks. But if (roughly speaking) 1/4 turn = 15 thou and your 1/2 turn = 30 thou, then Hughes' recommended 120 thou = 2 full turns, so something doesn't add up! That's why I'm trying to find some info specific to Mopar Performance.

Hi all, Firstly, yes I have searched on here and I've seen there is already quite a bit of preload info, but I couldn't see any that relates specifically to the cam and lifters we have. Koffel built us a 440 stroker a few years ago and the build sheet says it's a P5007698 cam. Googling only...

Bit of a late response but Uncle Tony is/was a journalist and founded the magazines High Performance Mopar and Mopar Action.

Haha.. confession time... we only have the stock temp gauge, in the dash :( It's only when the needle goes over to the right, near the double-line at the hot end that we start to worry. Even if we just had the electric fan on a switch to enable us to bring the temp down when it starts getting...

I had a look at the fan / shroud overlap and the back of the fan blades are approx 5/8" behind the back of the shroud. So maybe a bit more than 1/2 way inside the shroud but certainly not fully covered by the shroud...

Thanks, The trans cooler is not plumbed ino the rad as our rad doesnt any connections for a trans cooler. It's just mounted there to get max airflow. Yeah, I realise the 22" is a bit small, prob too small for a 440 let alone a 493! We should have changed the core support years ago when we had a...

Hi Don, do you mean the depth of the fan inside the shroud? I'll see if i can get a measurement this evening but I think it's about the recommended 'overlap', ie about 1/2 way inside the shroud. Will check tho. I know the shroud doesn't fit that well where it mounts up against the rad. Its...
