I know similar questions have been asked thousands of times but seem to be engine specific so here it goes...
I just did an engine swap on my '93 ECSB z71. The motor was a 0 miles rebuild with an Isky 256/262 cam and an RPM air gap intake. I swapped over the tbi after rebuilding and all other internals are of stock specs. It has new World S/R torquer heads though.
My question is with regards to base timing. I understand the processes for setting it, just not sure how to dial it in. I have played with it from 10 to as much as around 20 degrees, but haven't seen much indication as to where to set it. I have it set around 16 degrees now, but it seems to run very well from 12 up to 18. Is there something specific to look for? It has great power, no obvious flat spots on acceleration, no backfiring, maybe seems to smell as if its a bit richer the higher I set it (obviously). My concern is fuel economy and exhaust temps I guess so I'm not sure how to dial it in to ensure engine longevity. My truck will be pulling a trailer from here in nevada to Alaska in a couple weeks so wanna get it sorted out.
Any advice or insight is greatly appreciated.
