Remember to start slow with that stuff. Once you install the kit spray fuel only the first time by not opening the bottle. Remember to pull about 2* of timing for every 50 HP you spray. I think for reliability issues I wouldn't cram more than 125-150HP into that setup. I also recommend a good RPM window switch set to kick in about 3,000 rpm and shut off a few hundred RPM below your shift point/rev limit and a WOT microswitch so that it sprays only at WOT or just let the EBL control it if you are running that.

Re: More Power

I am not running an EBL rite now. I am going to have to get it tuned as soon as this is done.
I have the Cam, http://www.summitracing.com/parts/nal-12480002
timing change, http://www.summitracing.com/parts/clo-9-1157
the lifters, http://www.summitracing.com/parts/na, l-12371042
the locking plate, http://www.summitracing.com/parts/nal-12371042
Head gaskets, http://www.summitracing.com/parts/fel-1094
and intake gasket, http://www.summitracing.com/parts/mrg-136g
is there anything else I need besides the timing chain and water pump gasket?
the total comes out the $950 not bad for what it is and what I got. So basically I am making my motor a roller motor. That should free up some Hp.

I won't need to increase the size of the injectors? I know I'll need to bump up the Fuel pressure. The rest will be with the tune. What about using an EBL? I had one before but I couldn't get it rite so I sold it and had a chip burnt. Probably my bad and was no fault of RBob's as he bent over backwards to help me I just couldn't get it. Turns out to have been mech. issue that caused the tune to go in circles. I do admit it as in what the EBL does and can do was a bit over my head at the time. But I am willing to try it again.
