Great to see you enjoy bringing something back to as new condition, top job as usual.

[@graceenginedevelopments]

Thanks Philip I enjoyed doing that

[@kevowski]

It’s amazing how much time and work went into that rebuild!
Would be nice to know what car it went back into and how much power it made as a follow up?
Thank you for sharing 👌🏻

Thanks Kev, I'll try to get more info on it.

Nice! I am doing a head for a 2.5 10.5:1 street engine currently. also, is that a real Parker Funnel web in the background? I'm a small Ford guy as well. thanks.

[@ThabaniTBowseHadebe0909]

Excellent work. Would this head job be suitable turbo setup?

[@graceenginedevelopments]

Yes, it would need lower compression.. thanks for viewing

[@snhongo1]

[@benfrancis4628]

Nice! I like these 12v engines 👍🏻Do you have a preference between M20 and M30 mate?

[@graceenginedevelopments]

Thanks mate, to be honest I wouldn't know the difference

[@benfrancis4628]

@@graceenginedevelopments - older, bigger, chain driven and 3.0-3.5 rather than 2.0-2.5 👍🏻
All of which would be excellent in an Ace rep… 😁😎

[@graceenginedevelopments]

@@benfrancis4628 I'm doing a fair bit of BMW stuff at the moment

[@dolphin8219]

Is bottom engine is prepared too?

[@graceenginedevelopments]

All we did on the bottom end was a full balance

[@dolphin8219]

Is bottom is this with bore increase from 80 to 85?

[@graceenginedevelopments]

@dolphin8219 no it wasn't

[@graceenginedevelopments]
