I had a damaged engine come in for a complele rebuild, due to the customer trying to build it himself, twice around, bent crank, bearings shot, water entering from exhaust. So the customer at some point installed Edelbrock Performer 6155 heads, stock cam and so on after 20 hours of time he came to see me with it torn down. The first statement was about the heads and what the A/F ratio was going to be LEAN, put it on the dyno, 15.5-16 A/F called Mark, @ Precision Marine, told him what we had, and that was at 2:00 pm on Thursday, had it the next day @ 11:00am installed the Meth 3, had 12.5- 13 A/F ratio on dyno with headers.
Mark, has always taken the time to answer questions and deliver he hit it right one the money the first time, I completed the job and sent it on the way. My customer couldn't beleive it, over night and correct. THANKS AGAIN TO MARK @ PRECISION MARINE!
