I've heard that Tyler has done some work on them. Don't know anything more about it though.
A buddy of mine had a Whipple Charger installed on his 2002 496HO. It lasted about 4 weeks and blew. don`t know what at this time.
He was going to send it to Dereby Marine in Texas.
Who is good with these 496 8.1 motors???
I thought I read here that Tyler Crocket is real good with them.
Are forged pistons available???
Can you give us some more information? How much boost was he running? What blew? Did he drive it "hard"?
Don`t know what blew yet. I`m pulling the motor tomorrow. Boost was mild. 3-4 lbs. Yes, he is pretty hard on it.
Who should we send it to?
Tyler Crocket has been working with GMC and the 496's from the beginning. If they would blow one he would tear it down and report back his findings. He knows this engine through and through.
How do we contact him?
We met at the Miami show at the Clevelander I think My head is still spinning from that week
Tyler is the MAN!! He is located about 2 hours from me in Ruby, Michigan. His website is
Link to Tyler Crockett
If you end up coming to MI let me know we'll get together!! Give me a shout. 517-202-6611
Both Tyler Crockett and Arizona Speed and Marine have worked with the 496.
Both have or know where to get forged pistons for it. They can not program the ECU as they do not have the rights to the 555. However, Dustin should handle that end anyway.
If you think the problem is the lack of forged pistons you may want to contact Dustin. If the fuel curve is correct you don't need forged pistons.
Thanks for the info guys! Looks like Tyler is the guy for the 496
OG, yeah the Clevelander ...Risktaker was trying to bury us!
looking forward to the '04 Miami show!!!!!!
