Well...if this car's engine was built for Spec911 - it looks to me like it was a 'cheater' engine.
Cams do not appear to be stock SC - they are stamped Elgin "Super SC" - my research tells me these should be SC330 cams.
Pistons don't appear to be stock CIS parts either - any ideas what I'm looking at here:
I don't think these are CIS pistons.
Leakdown test prior to the tear down had some marginal numbers. I will measure everything and see how it looks, then make some decisions. I still think I can go for some bigger cams, pistons appear to already be higher compression than stock, but how high? I'll get the heads refurbed, twin plugged, and ported.
The rockers appear to be showing strange wear:
As for exhaust...anybody ever seen a set up like this one:
The headers are stepped design. Start at 1 1/2" and increase to 1 5/8"
This set up might be a weak link...and its showing some bad cracks. Last season an entire section blew apart and I had it repaired just to keep things rolling.
