Thanks - but no thanks - I need answers from someone who knows what they are talking about. You obviously have no idea what all the hype I spewed about my block means. Any fanatic can quote scripture - I.e. point to links. I need answers, not another opinion. The question was how much total timing can I run a 6" rod SBC block at. See beginning of thread for specs. The other was which is better for performance (out of the hole stop light to stoplight) the 750 Edelbrock or the 750 Speed Demon.

I am an engine builder as a hobby. It took me two years to design and build the 357CID SBC that is in my Wrangler. The vehicle does 0-60 in 5.2 seconds and weighs 4300 pounds. My 350 makes about 430hp according to Al's Custom Engines, with all the custom machining I have done. Every little thing you do when building an engine from scratch makes a difference. 5 - 7 hp here and there all adds up in the end to big power gains.
