I have a brand new Holley Sniper 550-510 for sale and also a used black one. They sell for $1070 on summit. Save $300 for new and $400 for used $875 plus shipping new $750 plus shipping used. The used Sniper is in perfect shape and boxed in original packaging. Shipping I would say would be 40 to 50 bucks in US. I'm going to put it up for sale locally as well so I keep everyone informed.
What else is needed to use this kit? Just fuel system and exhaust work for the 02 sensor? Will it work with a HEI or do you have to buy a new distributor?
I run mine with an MSD. It comes with a gasket for mounting the o2 sensor on the header or exhaust. Theres a kit that hollley sells that has the fuel filter and hoses that will work with your existing fuel system. I think it's $150 bucks
My existing fuel system is a stock tank and stock mechanical pump. I'll do some research and see how much a setup to handle EFI would run me. I'm definitely interested but don't hold up a sale waiting on me.
I'm out. Not enough money in the play budget right now to buy the Sniper and then upgrade my fuel system to actually be able to use it.
