[PONTIAC DUDE]

Jim. Couldn't have said it better myself. X 2

Pushing the envelop is fine for home builders & top of the class racers. But in this business, it's about driveability and customer satisfaction. Most that we build for never see the track and 15 hp wouldn't be felt even by a veteran racer. Especially with the built in torque the stroke and lower end head flow produces out of the box.

The idea of posts is to answer questions & post what works for 95% of the builds. One off or pushing parameters can get a shop in trouble. This IS the street section. I'm not into posting my years of knowledge and pages of technical jargon. LOL. Basic answer to a basic question.

Even if you tell the dude he might have issues, put it in writing, you damn well know that he won't take responsibility for a phucked up engine when the pistons melt. All his buddies will hear how "Quote..... that dude doesn't know what the phuck he's doing."

It's the machine shop s fault.

You want to build pushing the limits of today's fuels and emissions leaning toward lower octane with higher ethanol content in the future to "TRY" and sucker the public into Greenhouse control. Go right ahead and live with your build.

But still hold to my post and been doing such for 15 years.

9.5-1 with 93 and 8.7-1 or under 9-1 with 87 octane. Can higher compression ratios be achieved with carburated engines and chasing all the engine senerios. Yes. But.................

In 40 plus years I have seen just about most of it with ALL Brands.........
