Good photos Tim, and the last one is great. Seven cars and no two are the same. :D

Just remembered my Sprint racer became tax and mot exempt this year. I’ll have to figure out how to register it with dvla, then see if I can get a super cheap insurance policy on so I can take it down my road.......very tentatively that is as the slightest uneven tarmac will be a back breaker.

Anyhow, a distraction in the current madness to focus on.

Thanks Lou, it happened at 7000rpm so it’s ‘everything else’ I’ll need that’s the biggest worry. Rod 1 has a slight twist, exhaust valves 3 and 4 bent from looking up the ports, front bearing housing collapsed. First web journal has scored the block casting slightly. No visible scoring on bores 1 and 3, 2 and 4 rods look ok to my poor eyesight as on full down stroke. However I was laid on the drive under axle stands So it might all be bent an oval when stripped. :shock: :cry:

I’ll have to think it over before doing any more. Just took the sump and manifolds off today.

I’ve got a few short motors so let me know what you need and I’ll help where possible are you 8V or 16v
Cranks snapping Across that web Was not uncommon . Was the crank std ? I balance and nitride all my race cranks now

Oh dear, as you feared Tim.
Hope the block is salvageable.
Are you going to do a strip down or swap for your spare engine?

Not sure yet on next steps .

Thanks Lou, it’s a 1500 8v. Original crank was balanced up, not sure about nitride, I doubt it. I’ve got another 1500 block, and I have a couple of 1700 8v old class f type spec engines. I’ve got 3 spare steel rods from a previous engine, not sure if I could mix/match to any that are salvageable ? Can’t remember if they are the same manufacturer or not. I also picked up a steel crank (after the Original engine build unfortunately) but it is slightly stroked, and not a straight 1500. The rules for most classic series don’t allow stroking. I think I have another std crank, I also have some very old big valve flat heads with twin lobe reprofiled cams, 10.9 lift I think......just remembered about those.

If the pistons and heads have survived it might be recoverable if I can use the spare rods, and spare block if needed. However I can’t remember what each block was re-bored to, I’d assume / hope both are +4.

I’ll put a cold towel on my head for a week or so and think it over.
