Hehe, I’m pretty confident it will! The bigger question is how long the poor old Salisbury axle will last!

A quick update on progress, and a belated thank you for everyone’s valuable advice! We have arrived at a final spec, with -24cc pistons, of 9.7:1 compression which will run nicely on our pump fuel over here. The engine is not quite ready for the dyno, but the figures show 590hp and similar...

Hi chaps, A quick update. I decided not to argue the point with my engine builder, so we’ve dispensed with the girdle and he’s just used the supplied studs machined down a bit. I now have a useless slab of steel I can use as some kind of decorative garage furniture!

Thanks Moper, That’s cleared up my misunderstanding. I was just concerned that the motor would be a bit flat (Relatively speaking...!). Luckily, my Crane 689521 cam is apparently a good choice for my application according to my engine builder, with more appropriate pistons. If he agrees, then...

As I’m using aluminium closed chamber heads (Trickflow 240’s), does this mean I get the builder to work to 10.5:1 static due to what I understand to be the one point of compression difference between iron and al heads? Otherwise I will essentially be no better off than the standard 8ish to 1...

Garth, At last the bare block is with the builder! He has measured all the clearances, crack tested and sonic tested everything and declared it sound. As soon as I know all the final numbers I will post again. One thing that came up and slightly surprised me was, even though we’re going from...

I bought the Hughes girdle kit but having presented it, along with my block, to my engine builder he is quite reluctant to use it. To give a bit of background, he has measured the mains fitted with the supplied Hughes / ARP studs and tells me no line hone is needed (I thought one had to hone...

Garth, That’s a hugely helpful description, thank you for that and the link too. I really was wanting what you described with your engine, i.e. smooth idle and lots of vacuum plus plenty of grunt.

Garth, This is the sort of tech that I struggle with! What’s the effect of having the cam straight up instead of advanced in the way the car will drive? Is this a way of ‘bleeding off’ compression as was mentioned to me by an engine builder over here? Your 383 was fitted to the mk2 interceptors...

Hmm. That’s why I’m worried! It is to be a road car, actually not a Mopar but a Jensen Interceptor.

I am going to run premium pump fuel which is 99/100RON here in England, equivalent to your 93/94MON I think, plus an octane booster which will work out to about 97/98MON. As regards thicker gaskets, does that not have a detrimental effect on quench? Am I right in thinking that in itself can...

I’m new on here but would value some advice from you guys. I am in the process of gathering together parts for my 440 but I think I may have goofed in my parts choices in so far as the compression may be through the roof, and I hope you can put me right. I have so far, a Crane 689521 cam...
