Hello guys I am trying to figure out what heads wise for combustion chamber size to get to run on 87 octane. I am going to build a 350 next year and here is my build so far.
I am going with a 350 4 bolt with a cast steel crank and forged rods with hypereutectic flat top 4 valve relief pistons. The cam I am looking at is a comp xtreme engergy xr 270 with 218//224 duration @50 with 495/502 lift. The intake will be a weiand street warrior intake with a idle to 5500 rpm range.
The heads I was looking at was the world product SR heads. They come in either 76cc or 67cc combustion chambers. Summit also makes iron heads almost the same with 64cc comubstion chambers and I am wanting to make around 325 hp and be able to run on 87 octane. With the 64 cc I would be around 9:8 to 1 and with 76cc I believe it would be around 8:7 to 1.
What would be the right ones to get? Thanks Eric
