ok first thing you need to understand is this is not a gen anything hemi, this is not a gen anything small block, this isn't even a small numbers pontiac...
Slants are built buy people who want to build them, you cant "just" build one because. time involved is much like building a hemi, lots of time picking the right cam to make the motor run. my point is there is very little aftermarket for these, so saying my gen III blah wont get you anywhere but frustrated. you'll have the same or more in a 500hp small block but thats not why we build these.
all of us slant guys are more than willing to help as thats our crowd, but its a small crowd and many will tire quickly so tread lightly.
