Yeah the GM Bilsteins are nothing like the real German ones. GM loves to cut corners, so I'm 100% certain they told Bilstein to forget everything they know, and just "build them like THIS
" ... which was still miles ahead of any shock GM used prior.
I got 50k miles out of my struts - that's GM quality for ya right there. $30k for the truck for crap ball joints, crap brakes, and crraaaap shocks/struts. But I digress ....
TWIN big blocks! YEAH!!
Lots of fun! Just remember the general rule of thumb on the water is 1 gallon per hour for every 10hp at full throttle .... so if you got 1,000 HP between the 2, that's 200 gallons an hour, wide open.
But man that's sooo worth it!
I remember the general manager of a bike shop I worked at in Phoenix had a boat like that. Thing was like 50' long, low & slender, with twin SUPERCHARGED & MODIFIED 454's out back. He had these 4 blade stainless steel props put on at like $700 each back in '99. Well, he was showin' off for some hotties at Lake Havasu, and ran the props into the dirt!
Base of the blade was like 5/8" thick solid stainless, and it sheared it off like a pulltab on a beer can!! Blew all the gears out of the outdrive too! Man that was funny. We were all laughing at the guy (he was a dickhead). All money and no brains, one mechanic said.
Geesh in my selfishness I didn't even wish you well, Lisa. Guess I should slow down & READ these posts! Hang in there. Your dad is in our prayers.
