High compression Rapier engines are essentially the same as the HC alpine
motor, niether of which would have flat top pistons. Only the iron head
3 main motors like that of the minx and husky had flat tops due to the
fact
that the chambers had a lot more volume.
What you have is essentially a series 1 motor (1494).
The head is usable, but the valves are smaller than the SII.
The cam can be used in the SII, but that is about it.
The crank and block is set up for smaller journals across the board,
and machining the block for use as a 1592 is just plain silly.
Rods are useless.
Keep the oil pump as they are hens teeth.
The exhaust manifold sounds like the rapier unit, which sould be the
same as the series III and IV manifold.
Just out of curiosity, does the block have "1600" cast under the intake?
If the tranny input has 25 teeth "fine", then what you have there is a
late
SV tranny with OD "very desireable", but the breakdown looks like this.
10 teeth non-sync "S1 to early SIV" uses 8 or 8 1/2 inch clutch "early
flywheel"
10 teeth all-sync "later SIV to early SV" uses 8 or 8 1/2 inch clutch
"early flywheel"
25 teeth all-sync "later SV" 7 1/2 inch clutch only must use late SV
flywheel.
Any of the series alpine trannies will be suitable for use on any alpine,
but
the appropriate flywheel must be used as the different clutch covers have
different bolt patterns.
Hope this helps,
