87 GLHS looking for info on getting the engine rebuilt. To the best of my knowledge, everything is stock. Plan was to restore the car, meaning everything is put back the way it came out of the factory. I have already replaced the fuel system with stock parts (tank to injectors) and electrical (control computer, coil, sensors,etc), Now I'm thinking of getting more hp (maybe 100) out of it plus looking for advice on using an engine machine shop. But I want the factory look with the exception of exhaust size, I can waiver on that. I've worked on cars for nearly 40 years but the only engine I've built was a 1600cc VW and they're about as basic as it gets. So, things I've learned from the forum and questions
1. Most machine shops don't know our engines and usually want to replace everything.
I've heard keep the original pistons, anything else. Let the shop clean and inspect the block only?
2. Don't let them grind the crank, or block unless absolutely necessary. That's kind of a no brainer to me. I want as little metal shaved as possible. So far cylinder walls look ok but their is always some clean up. Is a mild cylinder honing job going to cut too much? How is the clearance?
3. Head. I've heard use a 16 valve head and I'm not totally against that but do I need it? Is a stock cam enough? Is a roller really better? I've seen both ways debated.
4. For the extra hp, I know stock fuel pump and injectors won't cut it. What size am I looking for?
5. Electronics for extra hp? Oil pump suggestions? Timing suggestions?
Thanks. I'm chronicling the build in the project forum. It's slow going but I try to keep it updated.
