Safe is a relative term . One guys safe isn’t another . Stock head gaskets ? Stock head bolts ? What’s the rest of the combo .
Your combo makes less with an underdrive because the smaller Crank pulley spins the blower slower.
You need to give the engine what it likes . Read the plugs for timing and fuel . Keep an eye on afr etc .
You’re asking about boost id love to know what the afr and timing is at ?
@a91what What ya think ?
Set it at ? That’s one thing . It needs to be pulling timing in boost . If it keeps adding the engine will not last longer then a few more times around the block .The engine is all stock. Head gaskets stock. I have shorties and full exhaust only. My cousin set the timing, I'll have to ask exactly what he set it at. And I still need to get an afr gauge. I've only driven it around the block.

i wouldn’t push it much further then 11 psi with everything bone stock
Is this the original engine that is at least 27 years old?

42lb, not chipped yet, stock ecu. Going to get it tuned probably using that sct chip. Stock fpr. 255lph pump to be installed.What injectors are you running ? Is it chipped or stand alone ? What kind of fuel management do you have ?
