I've got a Ferriday 1820cc low comp engine on S8 management in my XR2T, Crank and block is a standard Ford 1800cc with Fardon steel rods and 7.5:1 accralite pistons (it's the 1 the Ben Birch from retro ford had build for his old RWD XR2 project), Been running 13psi with no problems, It made 191bhp and 180lbs/ft on 8.5spi, The block on the 1800 is actually taller by about 10mm or so. Just fitted a T34 on a .48 cossie housing, will be going upto 18-20 psi soon as i get the downpipe fitted so should be up the top end of the 200's Bhp.

Only problem i've had was the head lifting when it hit the 6500 rev limiter in 5

to be honest though i only went for this engine as i know how much it cost to build and had it at a fraction of the cost

And the rods are supposed to be worse that the standard RST items.
