Motor and Drivetrain / Re: I want it i need it.....its time
« Last post by dsrace on April 03, 2024, 01:22:47 PM »I was wanting to go up to 400 hp on the engine, but I did not have a closed deck or good crank. I did a compression test before I tore it down and all were within 2 lbs of each other, but when I did a leak down test, the intake valves on #3 were whistling pretty good. Had them rebuilt and they broke a bolt off in the head and didn't tell me (they might have broke it on the final assy and didn't know?). Got the bolt out but it was a hard bolt to find. Special stepped shoulder bolt to align the cam bearing cap. The new turbo won't fit, the intake manifold wouldn't fit, the water crossover hit a vent tube, etc. Just the joys of new build/ But I am powering thru it. I did get to use my new bridgeport to ream out the heads for larger 1/2" head studs.
I know yours has run great for some time. Best guess where it was 9n hp before rebuild? I know 400 chp is the goal just wondering what the step up might be?
What did the builder say about breaking the bolt OFF?
that all sucksvexcept playing with the Bridgeport!
BrianN enjoys rebuilding the suby engines ..... just ask him
Your def having a challenging time like I have been.
