Don't forget E85. Even here in CA it is available pretty easy. It's cheap and will let you run as much compression as you want. I gave up some hp keeping the compression low enough for the raged edge of pump gas. When I switched to E85 Blair found some more hp and torque. If I had done 12 or 13 to 1 (which E85 would easily tolerate) and left everything else the same guess what more power.
I'd stick with the dual quad single plane TP and give yourself some inches. I know you said stock stroke but If 700hp is your goal then get a steel stroker crank and some crower rods and she will last a good long time.
I believe my motor will be every bit as streetable as you are describing.
Contact Blair Patrick. My TP heads flowed better avg numbers and better midrange than a lot of HR stuff. The unkown is what you loose from the rod in the intake. The dyno says not much.
I think Blair taught himself some more about big inch TPs with my build. I know he could lead you to 700hp with those heads with ease. Heck he already proved that.
fetorino,
Thanks for responding, especially about the E85. That is exactly what I wanted to hear, I'd like 13:1 if I can get away with it. I really want to stick with what we would have been limited to back in the 70's/80's and I want to experience that short stroke of the original 427.
I've heard some nasty things about E85 and it's ability to wreak havoc on the fuel system and it's components. Can you speak to that ?? Also, did you try a HR setup on your build ? Just for comparison sake.
Lastly, do you have Blair's contact info ? Thanks, Jim

Please feel free to call me Rob.
I did not try a HR set up. My intent from the start of my project was to build a TP. For reference without the pushrod tube my head flow better on avg and surprisingly better at low and mid lift than some of BPs good HR stuff.
The intake does hurt that some. Blair can speak better to this than I but with the intake manifold things are pretty even from a head flow perspective. Blair like the HR intake over the TP but that does come with hood clearance issues. You could fit a TP under a Mustang hood but a HR with spacers under the carbs, probably not.
The motor Blair did for me was based on some specific goals one of which was sustained high rpm beat downs of road racing. I also wasn't willing to spend the $$ to fix the Ford exhaust ports so my motor is held back because of that.
Speaking out of school because I'm not Blair. I think if you sent your heads to BP and let him go all in on the exhaust side combined with similar treatment to my intake port then 700hp with a 3.98 stoke isn't a reach with those TP heads. Since you aren't road racing your car your cam lobes could be more aggressive than what he used for me which along with the improve exhaust flow would get you where you are aiming easier.
It won't be a daily driver but it sure could be streetable.
As far as the fuel system. With E85 you need 30% more flow so guess what. Your entire fuel system, lines, pump and pickup will all be new and built for the E85. I don't have the long term experience to comment further other than I researched E85 and from that research gathered that the guys that run it would call BS on the corrosion piece.
It is worth noting that many oil manufacturers say due to it's high acidic content you should run a high detergent diesel type of oil.
Feel free to e-mail or pm me with any questions. I think we are both in CA.
