Probe Industries STREET FIGHTER Engine Kit - Ford 393W Reverse Dome -19.3cc http://www.coasthigh.com/Ford-393W-Reverse-Dome-19-3cc-Street-Fighter-Kit-p/10676-sf-f393w.htm are thay good?
SOOO..what do you want to know? I dont deal with them, since they F@(K^d a Budy. Banned in my book. Poor customer service, defective parts.
I ran one of their 347 kits years ago, very nice parts. And had good experience with their customer service when I had questions. Mark O'Neil, the owner, is a standup guy. Why a 393? For about the same money you can go 408. Resto, what kind of problem did your friend have?
I use DSS extremely happy with their service and products>http://www.dssracing.com/category_s/101.htm
I agree. Poor oiling in crank shaft, ruined 2 builds before figuring it out. Poor customer service when ordering replacement pistons and rods. 3 tries to get the right piston, wanted me to pay for overnighting the last one after they screwed up twice. Then the right piston didnt come with the spiral locks that I sent back with the first two pistons.
I got their Pro Street kit nothing but high quality pieces with no problems at all with customer service. I can tell you their SRS pistons can take some abuse, trust me I melted a few.
i ran a 347 pro street fighter and it seemed to be a good motor w/ good parts. However they did put the wrong length valves in the heads and I was getting coil bind at high rpm's. I had to fix that.
Well melting pistons doesn,t nessisrily make it the pistons fault. bad timing, not enough fuel and or too much N2o. usually this does it
