That's a bummer to hear about the Pontiac not working for the ExtReme front subframe at all. . .when that came out it had pretty much made up my mind as to the direction I wanted to go with the front subframe on my '67 Firebird. . .

We have had customers put the Pontiac motor in the Pro Touring sub frame but we do not supply motor mounts or have headers. the dimensions on the motor mount is along way back from the SB BB and LS that means custom mounts we can supply the parts needed to build some. Plus the Exhaust ports are really low and working the headers around the steering shaft or the other way around becomes the problem. Like a say less than a hand full of people have done it so it makes little sense from the r&D stand point.
we looked at the model and the Pontiac motor when designing the Extreme sub and there was just no way it was going to work inside our design criteria.
