[Fot] spit 1500 heads

[Norlin Engineering]

Don't know about the heads, but for the cam, I'd suggest the Kastner A-6.
TSI lists it and says it's marginal for the street, but I had a friend that
ran one back in the '70's on the street and it worked fine.

Subject: [Fot] spit 1500 heads


I am working on warming up a Spit auto X motor and am trying to get the
compression up to about 9:1  from the current 7.5:1 with my TKC3239 head on
my '75.  I understand the head thickness on the US market 9:1 head (TKC2748)
is 3.05" vs. 3.10" on the 7.5:1 head.   Was there also a change from dished
pistons to flat tops to get the increase?   Was the thinner head just that?
thinner
but otherwise identical?  I there a factory prescribed maximum amount that
can be milled froom either head.

anybody have a favorite cam for a 9:1 autocross spit 1500 they can recommend

Thanks!
