Anyone know if vulcan engineering modded 1.6 cvh engines with hepolite pistons will have hemi or lean burn pistons as i am looking at one i would like to combine with my current hemi head.

Thanks

I think hepolite made Pistons for both types, so it would depend which engine Vulcan had to start with?

seem to be a few pics of the hemi type hepolite pistons if you google it, was thinking someone might know if vulcan had a preffered type / route for tuning but i know its a bit of a long shot. I asked the guy to look down the spark plug hole but as ive done this on mine (hemi) you cant really tell.

I would be looking at the existing head casting number to identify what that is, hemi or lean burn.

Is there anything particularly special about the engine?
Not that grubby lump that appeared on eBay last week is it?

Yes that's the one, I say grubby as I was remembering the ancillaries and original rocker cover. Which presuming they belong to the engine in question, then it probably says something.

Looks to me to be a tarted up relatively unknown lump. Unless there's receipts or photographic evidence of the spec and any work undertaken, then I would probably give it a miss.

Casting number of the head is above intake ports 2 / 3 can't miss it really. Will start with something like 81SM, 86SM 89SM. Google the full number and you will find out what it is.

What exactly are you after from an engine.
I've had a look on e bay and can't find the engine you are talking about.
Are you after a standard engine to rebuild or one to modify ?
I have two 1.6 engines both from SS1's one with the cambelt gone turns over but locks up with some of the bits to repair 65k miles and I also have another one complete but I haven't seen it running was bought on the proviso that it was a runner.
If your interested let me know.

Cheers

Mike

finished yesterday, i was beaten to it fortunately or unfortunately. i am looking for a modded / race bottom end, 1.9 or overbored 1.6, light weight pisons or something like that. i have a standard one already, dont want to go zvh route as need to keep to historic regs.

Think this may be a very worthwhile gamble.

Consider the ford motorsport alloy rocker covers go for upwards of £150 alone now!

That head would probably look perfect after a quick trip to the vapourblasters.

If you are seriously considered in a 1.9 tall block I may be able to point you in the direction of one....

Many years ago my Noggin got a chance to go round the factory in Bradford, one of the lads who was quite high up management level worked there as a Metallurgist/technician IIRC.
They had just started production of CVH pistons for Ford, and he told us that after jumping through hoops to get the contract to produce the piston kits, Ford came back to them and politely ??? told them to drop the price to less than 2 quid each. :o
They had invested so much I think they must have.
