You have some mounting issues. I mocked mine up w/a 454 and there is plenty o' room... same as Spicer's. Send me a pic... somethign is off, if you're having clearance problems.
I pulled a hydro boost system off a 94ish Chevy K30. Turns out the accumulator is going to hit the engine valve cover (accum. is on bottom left). The pedal would have to be moved a long way to in any direction (up or left) to avoid hitting the engine with the HB.
Can a hydrobooster be mounted upside down?
I've heard some people have remotely mounted a hydroboost system with a bellcrank. does anyone have any pics of this.
