The porting

The porting

you saying the porting was a 15 h/p gain, how about the reeds and cylinder head and tuner?

[Powerabout]

dont know where you get the horsepower spec but yes
head is shaved and the tuner is different
reeds are stock but the rules allow plastic ones

70hp 56ci makes about 70 HP @ Propshaft.

SST 60, 56 ci make about 100hp @ powerhead = about 90HP @ Propshaft.
Head = 7-10 hp
Tuner = 7-10 hp and helps with over rev.........
Plastic reeds help a little.
No air box helps top end.

That is all.

thanks for the reply, nobody seems willing to speak up... i'm looking for a sst-60 cylinder head thanks again 75 man out

Everything you need to know is on the APBA web site for this engine.
The head is just a shaved stocker.
all the dimensions are there for you to copy

[ima75man]

man we don't copy, we make it better, that's why we are hot rodders.
