Thanks guys for the info.

Stu Cool: that 405 hp LS6 you recommended would be a blast. It would actually be my first choice in injected engines, but the complexity and cost of the conversion would be out of my league. I would also like to retain my Richmond 5 speed. Used LS1, LS6 engines and 6 speed transmissions are also very expensive in my area.

dr. Bowtie: the ramjet is good for 12 sec. et's? Now you're talking!! What are we saying here as far as aftermarket add-ons to get to the 400hp range (or greater)? New heads, cam, upgraded controller? Do you have any specific parts or vendors you could recommend to acheive that performance level with the ramjet? I was told (by an obviously uninformed friend) that the ramjet 350 could not be modified.
