Interested in where you found your rod bolts.. That setup should be pretty fun!

Good start, sir. I think it needs more injector, personally. Probably some 80's, at least, maybe some big boy 1000cc injectors and burn some corn.

700+ has to be pushing on those 60's pretty hard. But then again, I think you need to revisit your entire fuel system and run new teflon lined -8 to new rails and -6 back for the return.

Just my opinion, take it for what it's worth. And remember, I don't know ****.

Post up some pics of the setup. I too am surprised the 60lb/hr injectors got you as far as they did.

How was the On3 hot side? Did you do up your own cold side?

It's all on3 , I can't complain it's been on the car a couple years and hasn't given me any grief , there's a couple things I'dlike to do like vband the manifolds and swap some of the cold side piping cuz I don't like where it's run , but all in all its a great kit

Cool. Wasn't sure how much altering of the kit you had to do to make it fit/work. I've read mixed reviews. I'll be looking forward to seeing the pics.

Nice numbers. What kind of rpm did it spin to? Did boost hold all the way to the top?
