Thread: too much compression for daily driver??

Tweet

I have a 350 bored .030 with Aluminum Edelbrock E-tec heads. The specs are 2.02 on the intake with 1.64 on the exhaust. They have 1.6 roller rockers 64 cc chambers. They have 1.6 roller rockers. I'm running flat top pistons with Edelbrock performer rpm dual plane intake. The cam is Edelbrock RPM also. Is this setup too much compression for pump gas?? I want to be able to drive this on the street without using racing fuel. Guys, I really want to keep this setup; please help!

how many cc's are the heads?

Per Edelbrock................

Edelbrock E-Tec 200 heads have 200cc rectangular intake ports and 78cc exhaust ports. They outflow other similar aluminum heads by 10% on the intake and 17% on the exhaust, making power up to 6500 rpm. 64cc combustion chambers produce approximately 10.2:1 compression when used with flat-top pistons in 350-inch engines. E-Tec 200 heads come with 2.02" intake and 1.60" exhaust valves.......should run on 92oct fine.


Still like my trick flows better

Yes you can run it on pump gas

I ran a similar set up as yours in my 69 elcamino with 10:1 compression and was able to run 92 octane pump gas with no problem. I was even running cast iron heads which are more prone to detenation than the aluminum are. That elcamino ran like a bat out of hell, alot of folks sure didn't like being beat by a truck. I got accused of having nitros all of the time.

Stop blowing the horn to get traffic out of your way and they will stop accusing you of using n2o.....

Seems they think the horn button is the n2o button
