I am going to be closer to where I need to be with cam/intake changes and some weight reduction, but I am still lacking a small amount of improvement to go 5.80 in the summer heat. Going to run this index this coming year and just don't want to come up .05 short in the heat so looking for a realistic .10 improvement and also need to know what to do with all of this compression if I make the switch. Do I need a front mounted tank and engine driven pump with bypass? Can I use my current trunk mounted tank for alky since it is non anodized bare aluminum? I just hate to jump into something expecting $3k in cost just to have it cost me $5k.
