we've got decent enough fuel here, and our emissions regs are easy enough on something that age
not like the yank v8's, they need to run such low comp ratio's due to their strict emissions laws and crap fuel
high comp, big lumpy cam, nice intake, big carb and stainless exhausts= mega sounding car

I am very tempted by the kb 399 pistons for 11.1 cr but I don't want to end up building a grenade lol im only gonna be running stock crank and rods and crank is gonna be on 30 thou grind, also im running old cast heads aswell.
im undecided yet but those are my options 9.6 or 11 cr.
ive made some more progress with it.
front cover off timing chains a little loose ! lol
crank has some wear and a few grooves I have measured 11 thou under in the worst spot I could find so im just gonna buy 30 thou under bearings and that is that, same with bores 30 thou coming out aswell.
undone the mains cap and number 4 fell in half !
thank god I stripped it and didn't try running it, it wouldn't of been long and it would of eaten itself as bad as the motor in the car now !
crank and cam out on the floor, cam and lifters are all junk im going 268h comp cams kit which is biggest cam recommended for stock conv stall.
piston pins are press fit so I got the all off in my press.
cylinder heads all stripped now soaking in my cleaning bath.
I will clean the heads and block tomorrow with my pressure washer.
I bought some good used mains caps from the states there on there way.
ive contacted ivor Searle who are happy to do all the machineing I want doing.
so im gonna take them my rods, arp rod bolts, 30 over pistons once I decide what I want, 2 heads, a set of valves and the block.
il also take big ends, mains and cam bearings.
im gonna get everything tested for cracks if where all good they can fit the pistons and rod bolts then resize the rods, grind crank, resize all the mains aswell and bore block 30 over and lastly remove and fit the cam bearings as I cant be arsed to make something to do them with lol.
il get a valve job done and block and head faces checked for perfect square and that's it.
I havnt had a quote yet but I hope it should be within £1000 ish.
ive never really have to do a lot of this as the old cats very rarely fail its usually piston failure and there wet liners so its just fitting new pots and plugs. question is how close is my £1000 guess ?
