With all that you should have a pretty quick motor! Compression ratio has a lot to do with engine efficiency, looks like you are sorting that out with flat tops.
Cars looks #OOPS# hot, if you ditch the chromies it will accelerate and turn a lot quicker too.

cheers mate comp ratio is something like 10.5 -1 or 11-1 something along those lines...

what was the power figure promised?

dont wanna say incase its stupid lol all i wanna know is a rough figure and when i dyno it ill let you all know what i got

I don't reckon you'll get much better than the old engine without a decent electronic ignition setup.

The ignition system along with the head design are the most obvious aspects that hold the 'A' back from producing big power.

If you don't have a healthy fat spark you won't get impressive power figures.

Direct ignition with individual coil packs would have this baby buzzing!

yeah i got a electronic ignition as well out of a cressida i think it is..

just tell me i am interested in the old A14

I reckon 110hp at the wheels.

When it's all bedded in nicely I reckon you might be near 120hp (bit hard to tell without specifications though...)

What was the figure they gave you?

ohhk so its not too far over promised he has promised me 140ish atw
