Hi...

Now I am starting a new project.
I have a small block 350 engine and I will make it 396 stroker.

The pistons that I will use to my engine is Lunati pistons.
The pistons compression ratio:
APPROX. COMPRESSION RATIO WITH "64cc" CHAMBER=14.6:1
APPROX. COMPRESSION RATIO WITH "58cc" CHAMBER=16.1:1

The gas I normally use is 93-octane gas.

My question is : Will the engine works well (with no detonation problems) with these high compression ratio pistons and this kind of gas?

or,,,Should I use a race fuel?

Thanks

Pump gas, no way,
Racing gas, no way
Alcohol, yes.

How are you planning on getting it started? Push start?

Your gunna need a diesel pony motor to start this thing, then maybe you can change it over to diesel after you get tired of the detonation.

That CR is definitely way to high even to consider pump gas. I'm not sure how race gas can go up to, but it might even be a little to high for that.

Is there a reason why you are looking for such a high CR? There are other ways you can sqeeze out gobs of power.

Fastgas has 140 octane around $250? for 5 gal.s
Worked in my drag bike at 17:1.
You have to get the motor spinning then throw the ignition switch.

Not a prob with racing gas. I run 15 to 1 comp with vp112 . Engine spins over no prob with msd locked at 36 to 38 degrees

Some friends of mine used to run VP in a car with a 16:1 and 38 degreees of timming. Went through a few stock starters but eventually changed to a gear reduction starter. It will work just fine.

1BAD80 reminds me of a person I once new who had such small chamber heads and a large pump shot you would have to spin the engine, then blip the throttle to get it to start. If you didn't, hydro lock!

Exactly how do you intend to build a 396 out of a 350 case?
