Pulled the head off the 400 and this is what I found. Raised dish pistons? And there's that nick in the piston too looks like detonation. oh well nothing a good rebuild can't fix. But that's for another thread.
Here's that stage 2 necromancer cam. I'm not exactly sure what grind this cam is,but it's got about the right lift pattern for vortec heads since they stall at about 500 to 550 lift.
Here's a little bit of an update on the vortec 350. I ain't had much time to work on it since I wanted to take a break and start messing around with the split bumper again.
So part of the reason the engine failed I think.the knock sensor wire was severed from corrosion and heat. I was wondering...
I'm getting ready to say it looks right to me. I didn't take it apart or anything.i just took it off the other water pump because that one for the truck did not have the hole in the top for the bypass that I needed.
Plus the other one has the pulley for an electric pump set up for the turd gen...
I'm not exactly sure which one it is. I did have a 92 roadmaster motor do it could've been off of that.
But have I no use for that if the crank pulley from the original lines up
I'm back I got the whole engine together finally pulled all belt drive and shoved that on there.
Turns out I didn't even have to change the balancer or crank pulley. I thought the old 350 crank pulley from the Camaro would have to be used. but I didn't realize the balancer on that car was...
Here's the pulley for the vortec motor and then a l98 side by side (l98 left vortec right) I'm not sure if the l98 water and crank pulley will work with the rest of the TBI accessories. I'll have to look and see.
So I got curious about the 400 and this motor is cooked.4 bent push rods. spun bearing and no oil pressure. how this made it 40 miles home is beyond me.
