With that dish you end up with 10.5:1 roughly. I've got the 10cc dish down to 6.5cc and run 11.5:1. Due to the nature of the head design I can run pump fuel without an issue. XB Fairmont sedan : [email protected] |

would it be cheaper to just get a 400 'M' cleveland motor. and go from there. maybe you are after the rod ratio, and intake manifold options? more for drag racing. not the street driven 30000 km a year type that may like to try to get maybe 200000 km out

G'day Cleveland man
You may well be right.
However I have put my money down on what after much research finishes up as the same bottom end as Brenden.
The choice of cam and heads is what will change the characteristics of the two motors.

Set up right with a smallish torquey cam the components will last millions of kilometres if looked after (ie not run with no oil etc). My pistons were decked to achieve a high comp ratio but with my setup I can drop to a much smaller hyd roller camshaft a |

400M might be the way to go if thats what you already have but I think by the time you buy one and rebuild it then you've spent the money that could have paid for a stroker kit!
One of the american mags did a feature on this engine a few months back an

I think autos are the go with a 400 ci. the c6 auto is lighter than a fmx.
Ford increased the deck hight of, the 250 6 cyl over the 221 and 200. same with the 302 windsor and 351 windsor. 351 cleveland and 400M. for a reason? i say it's for a less stress

C6 lighter than a FMX? Are you sure on that? FMX is a car box, C6 is a truck box. I've had to lift both over the years, both clevo ones, and the C6 was a lot heavier from memory.

G'day Brenden
I guess you have been here before but I dropped off my bottom end at the balancers and got the phonecall to say that with a standard balancer we need to remove about a Kg from the crank counterweights.
So my flash "race spec" balancer need

No they used very short connecting rods in essentially 200 blocks. Ford USA did it properly and raised the deck height for the 250.

G'day Brenden
Already gone the Romac balancer route.
I won't machine my pistons now as the assembly has been balanced.
My reason for going for the 2V heads (including the advice from John at CHI) is that I am chasing more performance at a lower RPM ban
