Slant 6 Aluminum Performance Head

Charrlie_S said

Disagree.
Have had a turbo 170 slant since 1979, never ate a rod bearing. street/strip car 10-12 lbs boost
Sprayed a 170 a 225 HP and never hurt a rod. Pistons, yes
170 slant at 7,000 rpm never lost a oil pump or gear.
Nothing wrong with the nylon dist gear, very little load on it.
Most problems I have had is head gaskets, pistons/rings. Cause: detonation from a bad tuneup.

I was speaking for the 225, not the shorter stroke 'why bother' 170. Man.. even with a turbo them sons a bitches are SOFT...
See ... the 225 slant 'in stock form' is perfect...with thee exception of the exhaust manifold and induction....great motor... and the aluminum 225 was a great idea, I have one, but the open deck sucks and the liners separate at the tops from the die cast sleeves that capture them .....and then they leak at the head gasket cause of it.


Imho... if you really wanna help the slant, offer a new AL block that has a deck and then a cnc program for the existing head along with valves that gives 200 cfm by .500 lift...Last would be a solid roller...
