Stretch,

I am finishing one up in an SPF. The engine is the basic terminator with some modifications for strength, some for safety but also some for power. You can see a few of my initial build pictures in my gallery. I hope to finish up in the next month or so and post a bunch of final assy type photos.

If you do it I think you will be quite pleased. Be sure to check out Sergio's Cobra4Me site where he documents his build. Quite impressive!

BTW you don't need to spend a lot of money porting heads and buying cams and such for these engines. The blowers change everything. A Whipple or KB with the stock top pulley and an 8" lower is good for about 600 - 630 HP with great street manners and Massey Fergusson Tractor like low speed torque. With the blower it is not hard to get 500+ lbs-ft of torque at 2000 rpm or lower.

The closer you look, the more I think you will like the combination. Just as an aside the visual WOW factor when you lift the hood is massive. We have not had an engine that fills up the engine compartment the way this one does since the 427 SOHC, and they are light. My complete engine is right at 400 lbs.
