Absolutely a must if you get an engine built is to B&B it.
My current engine ( 347 Windsor) revs smoother than any engine I've ever had...Zero vibrations...it's brilliant.
BUT...
I have to admit I did have some probs with engines ...that's for sure.
But they can blow for the dumbest reasons....
I lunched one engine, even though I recon it had been built beautifully, went like the clappers, and was completely balanced and blueprinted.....all it took was a series of little mishaps.
I overrevved the engine , when I lost all grip momentarily accellerating out of the pits onto the track, with slicks on a wet patch at Queensland Raceway....
Poor little 302 Windsor went to about 8250 rpm instantly, and broke a little piece off a valve spring.
That tiny little bit of steel found it's way to the sump.
This is where the second little mishap had happened unkown to anyone.
At the post mortem it was discovered that hidden out of sight in the sump, the gauze cover/ filter over the
oil pick up had broken off....
probably didn't allow enough clearance when the sump was put on...
and with the gauze filter sitting in the bottom of the sump doing F'All , the
oil pick up took that tiny little bit of valve spring up into the
oil pump.
That bit of spring then got jammed in the oil impellar...seizing the oil pump, and turning the oil pump drive into a cork screw....no oil getting into engine...then as I was trying to stop , the corkscrew jammed itself against the conrod ....everything stopped turning instantly.....and within a very short space of time I had a shagged engine.
All that balancing, and using all of the very best ( and expensive ) engine components, all went down the gurgler when that little bit of spring got sucked into the oil pump.
The NEW engine has also been balanced and blueprinted, and there is now a rev limiter always in place, and I triple check everything all the time...and it has been excellent.....
TOUCH WOOD.
Cheers,
Warren.
