24x SBC conversion starting issues
Hi All,
I've just rebuilt my motor after some unfortunate block, head and cam damage, and I'm back to where I was previously which is getting the thing to start and run properly.
This time around I made sure the motor was at TDC on compression stroke and set the vortec dizzy in place before lowering the motor into the car, so I'm fairly sure that side of it is correct.
Previously the car would cough splutter and backfire when I tried to crank it over.
This time around (I've only tried twice so far) it almost started, and then just wound over without firing, I'm wondering what else I should check before continuing to try?
I've attached the tune file, along with the last scan I did, as short lived as it was.
Plugs are clean, leads are good, crank sensor was working fine prior to rebuild.
Build is a 408 SBC stock bottom end, -12cc pistons, around 10.8:1 compression, AFR heads, Holley stealth ram intake, MAFLess setup, 28lb injectors, XFI280HR cam, 1.6 lifters, 4l60e transmission and 24x conversion, coil per cylinder etc.
