Thread: 434 SBC info needed

Tweet

First, I would recommend using a Dart block rather than a WP Motown block because Dart has had a lot less issues with qualitly control. Secondly, I would call CompCams, Isky, Crane and Crower and see what mechanical roller cams they recommend for your application. Then go with the specs that are the "average" of all four recommendations. After that, call AFR and talk with their tech people. Their CNC 227 heads would be a good choice IMO, but I would get their input as well regarding chamber size and the possibility of some personalizing for your heads. American Speed in Moline, Illinois builds a 434 small block putting out 600 hp, and they use AFR 227 heads in their build. Let us know what you come up with.

Might check with this guy for some very nice heads, He spent a couple years and Mega bucks building a UMP modified took it out the first night and got to run a few laps,spun a bearing and popped a rod. He decided that was the end of his racing career.Plus he got laid off last month so he might be willing to deal. Might be worth checking into. He lives in St.Peters,Mo.

I'm going to be dealing with a company called Ohio Crankshaft. They are a few hours south of me. The block comes part of a short block assembly I will be getting from them. I bought a rotating stroker assembly from them a few years ago and was very pleased. Don't get me wrong I do believe the dart seems to be superior according to what i've heard time and time again but I am confident that they will take good care of me. Not saying I won't decide on the dart but as for now thats what i'm leaning towards.
I ask these questions on here because everyone here are the customers of all these companies and have more feedback towards these companies. Any company i call asking for recommendations are more then likely going to stick with their product being that its their job to.
I was thinking about the 210 cc heads at first thought but more i thought about it the more I started to lean towards the 227's being this will need to breathe like big block.
