Ryan Tremblay's 535 c.i. / 820 HP Pump Gas Trans AM
Ryan sent us this email telling us about the engines performance
"Thanks Butler Performance for the amazing combination. 829hp, 700ft lbs. on 92 Octane pump gas, all under a factory hood and working shaker. Over 1100hp with NOS. This combo is insane. The FAST EFI system makes it a true street machine with the drive-ability of a Ferrari no matter what the weather is. Just turn the key, step on the gas, hold on, and scream. You sent me all the parts I needed to build my own engine with the utmost of professionalism all the way. I have already put over 3000 street miles on the engine with no issues and not even a change in valve lash- insane durability and street manners given the high HP combo. I have had the opportunity to do a top speed run on a runway, and I was able to hit an estimated top speed of aprox. 203 mph (325kmh) on pump gas, in less than 20 seconds (The car is good to 180 mph and then starts to float!) I then turned right around and drove home and averaged 20+ mpg."
