LOL, You have a good combo against the comp. But, I think we'll just disagree on this. I'll say you have street parts to the day I die.
Cast cranks are not race cranks. I wouldn't want to run around or race 700 HP on a cast crank. You go on ahead and do so. Not me.
Your preety happy that you have 520 HP. And thats good. I'll be straight up honest and say I'd be happy as well. But thats not what I'd call a motor for racing. It's low powered with a cast crank.
In a race arena, it is asking for trouble IMO. And 11's is not fast. If it is for you, then thats great and I take nothing away from that or you.
DO NOT be insulted or come back screaming at me, I'm just trying to put into focus a race car. Not something I'd call a street strip car that I would drive everyday to and from work and anywhere else.
For me, that is what you drive. It is simply a case of different strokes for different folks.
I'm sure your engine builder is capable. Why you bring him up is beyond me. But ask him, would he himeslf build a 700 HP engine to go racing with your parts or would he step up to the plate with better parts?
