I think I found my answer in the force induction section but wanna double check here. 5.3 lm7 supercharged at 6-8psi and prolly a 100ish shot. From what I’ve read using the ngk tr6 4177 the gap should be .025, sound correct? Just looking for a starting gap as I didn’t find a spark gap on a boosted and sprayed engine, only one or the other. Engine is on stand now.
