Car drove well on way home. I couldn’t help myself and drove gently as if running in, even though I know its a good engine. My Dad rebuilt this engine for a Spitfire, including a a new crank. I drove it several thousand miles in that car, somethimes fairly hard, and it never showed any of the issues the old engine had.
I should have given up on the previous engine and fitted a replacement engine long ago – there must have been some fault with the block or crank in the old engine. I did read that a spun bearing can throw the indexing out by causing the crank to overheat and distort so maybe the damage was done right back at the end of the season before last. I guess I put too much faith in the professionals who rebuilt it. Anyway – its gone now!
Anyone know of someone good with twin SUs in Norwich? Could do with balancing I think. It really ought to go on a rolling road as the carbs were set up for the old engine. They are the same spec though so it shouldn’t be too far out.
To celebrate I’ve ordered some new Valvoline racing oil and got my books out (see recomended stuff).
