well the engine was put together a year and a half ago now, only done 5k in that time.
And yes I probably should have done the port and polish back then
I just dont like the smoke on startup............compression is "roughly"10.1
Its a f54 block, p90 head shaved 2mm, flattop pistons, stage 4 cam and triple dellortos, and its an NA motor
I thought there was something wrong with cylinder 6 as the reading was much higher than the rest
I'm using 20w 50 oil at the moment.
