These engines will produce good torque, not quite like a DI, but they will produce more than enough for our needs, the key with these engines is getting the fuel in past 4000rpm... You can strap on big blowers, but when they only start coming on strong past 3000rpm, you've got 1000rpm to play with...
The ENGINE will rev happily, but getting the fuel pump to play ball is the fun part!
Also, out of interest, where did you get the 78%VE figure from, Jarrus, I'd always seen much higher figures quoted for these engines - the 8v head as stock flows very well - and being an IDI, you're not worried about swirling, so you've not got to worry about the valves doing the swirling for you - just make them pass as much air as physically possible.
