Mild 360 Magnum Build

Thanks so much for sharing! I will be starting a build just like this very soon. I have the same heads as you, and have been on the fence about what pistons to use.

do you know your cranking pressure in the cylinders?
What octane did you run, and what do you plan on running the engine with? I am also in Canada, and limited to 91 at best.

thanks again for sharing!

It had Co-op 91 in it only because they had another engine to do the next morning and it would save draining the tank...we did no tuning other other than timing and I know it could have went well over 40 degrees and made more power...made 400hp with no spacer and a rich A/F reading...stuck the carb spacer on it which leaned out a bit and went 410hp...and we left the shop...total time on the dyno was under 1 hour
