Hey everyone,
I am restoring my 1993 k1500 blazer. I have had it for 16 years. After tracking down discontinued interior trim pieces and getting way to good at using epoxy on those I couldn't find. I have finally made it to the engine restore.
The stock L05-k has been fantastic. Still running strong with 300k+ miles. But I would like more torque in my new engine. I've decided between a few options. I'm in Cali so "smog"legal only. That means stuff they can't see is OK.
First- a brand new GM L05 crate. Either keep it as is. Or put in a mild cam and take the extra 15-20 lbs of torque. Obviously the easiest, less issues option.
Second- a brand new L31 engine. With the gmpp TBI to vortec intake. Have to plumb EGR but should yield 20-30+ hp/lb for similar price as L05 and cam.
Third- is this engine

I talked to techs at blueprint and went over most issues I could think of with thier 383. They were very helpful and even went over some of the changes needed in the new chip.
Only thing is will it be a lemon or a good engine?
They were confident it would run well with only their chip tune. Maybe a up in injector pressure.
Any helpful hints or opinions? Been searching the interwebs for months now. Read most all tips and tricks.
Looking for 340-400lbs torque. Don't care much about high rpm HP.
Any info be great thanks!
